Hauraki Gulf struggling to keep up: new report

N

ew Zealand’s Hauraki Gulf is struggling to keep up with the effects of population growth and climate change, a new report states.

The State of Our Gulf prepared by the Auckland Council every three years highlights the issues; poor fish and marine life stocks top the list. Species such as snapper and crayfish are now only 20% of what they used to be.

“The pace of change is outstripping the ability of current management frameworks to respond effectively,” said John Tregigda, chair of the Hauraki Gulf Forum of the Council which oversees the report.

“Demand for facilities, infrastructure and resources

are pushing development towards the sea, and fisheries indicators point to significant stress.”

Other pressures are from increasing amounts of chemicals and pathogens due to storm water overflows, septic tanks and livestock, the spread of mangroves, increased littering and the expansion of recreational facilities.

The Hauraki Gulf Forum is calling for central and local government, as well as iwi, to work together on a renewed, integrated programme of action, an approach which has remained elusive for the past 17 years.

Due to climate change the Hauraki Gulf will become warmer and more acidic, and risks associated with invasive species will increase.

On the positive side, the number of Bryde's whales being hit by ships has been reduced. Until four years ago, two on average were hit and killed every year.

Now, after discussions with shippers, virtually all ships travel at 10 knots, and just one has been struck in the past four years.

“Nutrient loads from the Hauraki Plains and heavy metal concentrations in Auckland’s urban estuaries remain elevated but there are signs of improvement, and biodiversity gains are progressively being made on the islands of the Gulf. But pressures are rapidly mounting as the population increases.

Eleven key indicators The report says: “Eleven key environmental indicators have been used to assess the state of the Hauraki Gulf or Tikapa Moana/Te Moananui-a-Toi. “These are: fishing; toxic chemicals; sediment and benthic health; mangroves; nutrients; microbiological contamination; non-indigenous marine species; harmful algae, pathogens and mass mortalities; maintenance and recovery of biodiversity; litter; and, coastal development.

“Of the top 15 finfish stocks caught in the Gulf, only four are at, or above their target levels (kahawai, albacore tuna, baracoutta and gurnard). Snapper are overfished, john dory is Most fish stocks in the gulf are in decline.

“Toxic chemicals, such as heavy metals, affect urban estuaries in Auckland and the coast in the southeastern Firth of Thames.

State of Gulf Report a further wake up call

L

ike a cancer, metre by metre, litre by litre New Zealand’s Hauraki Gulf, the big pond that leads you to New Zealand’s largest city, Auckland, is steadily losing its battle to maintain a healthy environment for all marine creatures, birds, and for people to enjoy.

Many of you would be aware of the recent 106 page Report released on the 2nd March 2018 by the Hauraki Gulf Forum which is a statutory body charged with the promotion and facilitation of integrated management and the protection and enhancement of the Hauraki Gulf.

The media have naturally jumped on the data relating to commercial and recreational fishing.

Stating numbers such as the snapper population is approximately 20% of what it was in 1945, and about 50% of marine life in the Gulf has vanished in the past 93 years, and other depressing statistics. This is the fifth such report. The first being published in 2004.

For me the first part of the report was the scariest.

This section looks at the environmental impact on the water quality and the Gulf’s coastal shoreline as urbanisation of land in Auckland and the Coromandel continues unabated.

The list of the environmental and infrastructure problems facing local councils and central Government due to our expanding population, is mind boggling.

The issues that the report lists just seem so massive you wonder how the creeping cancer can be halted. The momentum of urban development and farming on land and in the sea seems to be unstoppable!

There is a heap of ‘numbers’ in the report; here are a few: • Auckland Council manages around 6,000km of storm water pipes, 20,000km of streams, 150,000 manholes and 370 ponds and wetlands.

• Watercare Services manage around 8,000km of wastewater pipes, 18 wastewater treatment plants and about 420,000 wastewater connections.

• The cost of providing new infrastructure to service Auckland’s greenfield areas (undeveloped land) alone is estimated to be $20 billion over the next 30 years • Development is increasingly sprawling onto the coast. In 2014, 2900ha of marine space had been zoned or consented for mussel and oyster farms, with a further 390ha zoned for fish farms.

Maritime NZ protects Poor Knights reserve A total of 19 infringement notices were handed out last year for ships illegally entering the Poor Knights marine reserve, up from five the year before and 10 in 2015; now Maritime New Zealand has mounted a campaign against their recurrence.

Fishing is prohibited in the reserve and ships longer than 45 metres are banned from the designated “area

to be avoided” which includes the Poor Knights reserve. Maritime NZ Specialist Investigator Nick Dowden says their Maritime Operations Centre actively monitors a digital geo-fence which alerts the centre to ships entering the area. Crews are then contacted by maritime radio and instructed that they must leave by the shortest and safest route.

Mr Dowden says “We take transgressions against the environment very seriously. He says the offenders are generally the operators of visiting cargo ships, which navigate a direct line down the east coast of Northland to save time and cost.

“Breaches can land the operator of the vessel with a $12,000 fine and the master can be fined $2000.”

Elite divers take legal action after deep dives Six elite divers who suffered brain injuries during Australia’s deepest ever commercial dive have engaged a Perth law firm to sue for substantial damages, reported John Flint in Perth Now mid February. (Dive covered the story in our last issue – Claims deepest ever dives led to brain damage) The claim is understood to focus on why divers were pressurised very quickly causing them to feel “fried” during the dives off West Australia’s northern coast in June and July last year. Other divers are continuing to experience bizarre neurological

symptoms and may join the legal action.

During the dives to depths of up to 273m, the divers experienced hallucinations, nausea, headaches and tremors as they worked to repair a pipeline on the ocean floor for Inpex Australia’s Ichthys LNG project.

The very quick compression (“blow down”) schedules are at the centre of an investigation by the federal regulator, the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).

The first three diving teams of nine men were allegedly “blown down” in eight hours, while the fourth and fifth teams were allegedly “blown down” in five hours and 20 minutes.

Their union claims blow down schedules for deep saturation dives of 230-240m elsewhere in world range from 17 to 26 hours.

The DOF Subsea schedule complied with US Navy schedules, but according to saturation diving experts, the faster blow downs allowed by the US Navy are for emergency situations only.

USS Lexington located The wreckage of US aircraft carrier USS Lexington sunk during World War Two has been found at the bottom of the ocean after 76 years.

More than 200 crew members died when the carrier was destroyed in May 1942 during the Battle of the Coral Sea fought between American

and Japanese forces.

The ship was discovered off Australia's east coast by a search team led by Microsoft co-founder Paul Allen.

Pictures and video show the carrier appears well preserved after more than seven decades underwater.

Finally, a couple of quotes: John Tregidga, chair of the Hauraki Gulf Forum, says:

Stephen Hawking, the renowned physicist who recently passed away, was regarded as possessing one of the world’s greatest minds. He said: “We are in danger of destroying ourselves by our greed and stupidity.

Northland man loses prosthetic arm, Paihia divers find it Paihia man Ty-Ray White is giving a "big hand" to the divers who helped find the prosthetic arm he lost while wakeboarding in February, reports the Northern Advocate.

White was wakeboarding off Te Ti Beach when he fell, and during his fall, the prosthetic on his lower left arm "slipped off".

The arm made of carbon fibre did not float and he thought that could be the last he saw of it.

He is reported to have said it was an "I told you so" moment for his wife Karen who only minutes earlier had reminded him he was supposed to have a form of floatation on the arm in case it fell off. Mr White admits his “she'll be right" attitude didn't pay off.

He put two pairs of divers down in different spots - one near the ski lane marker buoys and one where Mr White thought it might be. The plan was to search for half an hour and then resurface and re-assess.

Right at the end of the search pattern, they were just about to give up when Adam Scanlon found it in about three and half metres of water, Craig said. The hand part of the arm was dug into the sand, but the neoprene sock on the other end meant it was floating upright.

Paihia man Ty-Ray White wake boarding near Waitangi moments before losing his prosthetic arm and later recovered by divers.

He said Scanlon was "absolutely chuffed" to make the find. He added it was the first arm the company has ever found.

Mr White was born with only one

hand but says it has never held him back.

But next time he will put a flotation device on the arm while in action on the water ... just in case.

Mr White, a former professional diver, thought the poor visibility in the water and current would make the arm impossible to find.

But Mrs White put a post on Facebook asking for anyone who might come across the arm washed up on the beach by a stroke of coincidence to let her know.

The post was spotted by Craig Johnston, owner of Paihia Dive and he decided to pop out and have a look, free of charge. Johnston said the visibility was about half a metre.

Volunteer divers kill thousands of crown of thorns starfish Volunteer divers have killed almost 47,000 crown-of-thorns starfish on the southern Great Barrier Reef in just seven days, breaking a record in the process.

Queensland Parks and Wildlife were also part of this expedition, surveying the reef and identifying where the concentrations of starfish were.

Scallop sees world with hundreds of eyes (From The New York Times)

While some invertebrate eyes sense only light and dark, scientists have long suspected scallops can make out images, perhaps recognizing predators quickly enough to jet to safety. But scallop eyes, each the size of a poppy seed, are tiny and delicate and scientists have struggled to understand how they work.

Miniature mirrors made of millions of tiles But recently a team of Israeli researchers reported in the journal Science that each scallop eye contains a miniature mirror made up of millions of square tiles. The mirror reflects incoming light onto two retinas, each of which can detect different parts of the scallop’s surroundings.

Our own eye has been likened to a camera using a lens to focus light on the retina. The new research suggests that scallop eyes are more akin to another kind of technology: the reflector telescope of the sort first invented by Newton and today, by astronomers gigantic reflector telescopes built to look in deep space. They also build their mirrors out of tiles.

Earlier studies had hinted the scallop eye was weirdly complex, each with a lens, a pair of retinas, and a mirrorlike structure at the back. Scientists suspected that light passed through the lenses and the retinas, which are mostly transparent, bounced off the mirror, and struck the retinas on the return.

But no one knew how the mirror works, or why scallops needed two retinas when other animals need only one.

Cryo-electon microscopy Using new cryo-electron microscopy,

…‘Each scallop eye is built something like the gigantic telescopes that peer into deep space, researchers report’…

Photo: Wikipedia

Inside the hinged shell of the scallop lurks a musclebound creature that’s best enjoyed seared in butter. But there’s much more to appreciate about this delicious entree: the scallop sees its world with hundreds of eyes in an array that mirrors microscopically a giant space telescope.

Benjamin A. Palmer, a researcher at the Weizmann Institute of Science in Israel, and his colleagues froze slices of the eyes, making it possible to inspect the tissue down to its fine molecular details. (Last October three pioneers of cryo-electron microscopy won the 2017 Nobel Prize in Chemistry.)

Two retinas

Researchers have long known that the mirror in a scallop eye is made from a molecule called guanine. It’s best known as one of the main ingredients of DNA, but in some animals guanine is packed into crystals that reflect light.

One retina can create a sharp image of what’s right in front of the eye.

The other retina gives a better view of the periphery. The retina that sees the central field of view might allow scallops to quickly recognize oncoming predators, allowing them to beat a hasty retreat by swimming away.

Transparent, flat square guanine crystals Some fish have a silvery tint to their scales thanks to guanine crystals.

Chameleons use guanine crystals to help them change the colour of their skin. But no one knew how guanine helped scallops to see.

Dr Palmer and his colleagues discovered that scallops make a kind of guanine crystal never seen before in nature, a flat square. “We were amazed,” he said.

The researchers found that the mirrors are made of twenty to thirty layers of guanine, each containing millions of squares that fit together snugly like tiles on a wall.

Paradoxically, the guanine squares don’t reflect light on their own; they’re transparent. But their arrangement turns them into a collective mirror.

The model created by Dr. Palmer and his colleagues may also solve the mystery of the two retinas. The researchers found that each retina receives sharply focused light from different parts of the animal’s field of view.

Scallops may pay attention to their peripheral vision instead when they’re searching for a spot on the sea floor where they can settle down to feed.

What’s more, the hundreds of eyes on a scallop all deliver signals to a single cluster of neurons, which may combine that information to create a rich picture of the outside world.

Dr Palmer said that scallop eyes may provide inspirations for new inventions. There’s certainly precedent: NASA has built X-ray detectors to study black holes that mimic lobster eyes. Perhaps an artificial scallop eye could take pictures in dim seawater.

But Dr Palmer is more excited by the prospect of creating materials new to engineering. His study shows that scallops have evolved a mastery over forming crystals, guiding them into shapes that researchers didn’t think possible. https://tinyurl.com/yb6vcvdf

Making a splash in the fight against cancer

South Australia dive for cancer group

A

group of committed individuals sacrificed their pre-breakfast gym sessions, spin classes and morning tv to plunge in the ocean in February, for the noblest of causes: the fight against cancer.

The 5th annual Dive For Cancer was held again at picturesque Port Noarlunga in Adelaide. This year the event sold out in six hours - the biggest ever - attracting 130 divers and hundreds more supporters.

Flippered participants were noisy and colourful as always and their efforts raised nearly $30,000 towards cancer research.

As always, Mark Tozer, the driving force behind DFC, made sure there was plenty of dry land entertainment for anyone within a mile of the jetty.

The Dive For Cancer auction saw more than a hundred items go under the hammer, among them a holiday, a white shark trip provided by Andrew Fox and a stunning Leafy Sea Dragon painting donated by renowned artist Miranda Peta Lloyd. Mark Tozer received an award from Padi for Outstanding Contribution to the diving community.

The money raised brings the total raised in South Australia alone to more than $100,000 since the event was launched in 2014.

“Every year, our footprint grows,” he said. “But I know there is a lot more to be done. And it’s wonderful to be surrounded by people who are up for the challenge.”

Hoki fishery stock healthy for now I

n the annual assessment of New Zealand’s hoki stock last year, National Water and Atmosphere Institute (NIWA) fisheries scientist Richard O’Driscoll and his team measured 71,752 fish.

Hoki is used in fish burgers, fish fingers, crumbed or battered fillets, or fresh. Commercial fishers can catch up to 150,000 tonnes of hoki during the season worth $229m in 2017.

The biennial trawl survey on the Chatham Rise identifies the numbers of juvenile fish from both New Zealand hoki stocks: one that spawns on the West Coast of the South Island; the other in Cook Strait.

The hoki population has undergone some large fluctuations in the last few decades. In the 2000s, the total allowable catch was drastically reduced from 250,000 to 90,000 tonnes following successive years of few younger fish appearing. Since then the quotas have gradually increased as the stock has grown and this year it is set at 150,000 tonnes.

Warmer seas a challenge for tracking whales A two-week expedition to tag blue whales in New Zealand waters for the first time almost came up empty due to warmer sea temperatures causing the animals to change their behaviour.

NIWA megafauna expert and marine ecologist Kim Goetz led an expedition recently hoping to tag up to eight blue whales to help understand their foraging and migration patterns. The tags transmit location data via satellite.

waters are around 13-16°C. But we had water temperatures of 20-22°C and we are currently in a La Niña weather pattern which is not conducive to upwelling of nutrients in the Cook Strait region,” Dr Goetz said.

The original plan was to locate and tag the whales in Cook Strait and off the coast of south Taranaki.

Upwellings occur when deep cold water rises to the surface. This water is rich in nutrients and plays an important role in the productivity of the ecosystem, which ultimately influences the movement of marine animals.

“Usually when whales are found off Taranaki, there’s a lot of upwelling going on and the

“We spent the first couple of days searching the area off Taranaki where we suspected the blue whales would be but came up empty.

While sheltering from bad weather in Westport, Dr Goetz and her team spoke to tuna fishermen who confirmed that the whales were 20 to 30 nautical miles offshore from Westport.

“The whales were feeding at depth - staying down for up to 10 minutes at a time.

“We were able to attach tracking devices to two whales which, on reflection was really good. The tracking devices, which should last for four to six months, show both whales are now heading north.

“This will give us novel information as it is the first movement data for this species in New Zealand waters which is very exciting.”

LegaSea Update

Fisheries review demands priority

L

egaSea has repeated its call for an independent Commission of Inquiry into the state of fisheries management in New Zealand.

In particular crayfish stocks are in crisis. Currently, crayfish in the CRA2 region from Pakiri through the Hauraki Gulf to the East Cape, are at an all-time low.

At the start of the current fishing year the amount of legal crayfish in the water represented five per cent of what was available before large scale fishing.

In the Hauraki Gulf, several scientists recently described crayfish as “functionally extinct”, unable to carry out their natural function. Yet MPI has continued with its laissez faire, hands off stance.

Spokesman Scott Macindoe said: “The Quota Management System is allowing industrial fishing to take place without effective governance from the Ministry that is charged with managing marine resources on behalf of all New Zealanders.

“Instead, MPI has stood back while the fishery has declined to the stage where even experienced divers struggle to find even one legal crayfish in a season.”

what they believe needs to be done to save this fishery.”

“Commercial fishers have doubled their cray potting effort over the past 16 years and yet they are catching fewer crays now than what they were at the beginning of the century.

“By all independent measures the stock is collapsing. This isn’t about recreational and customary rights versus commercial rights, it’s about ensuring sustainability and healthy ecosystems taking priority, and it’s about protecting the resource for our kids and future generations.

“We need to stop this madness in CRA2. We need a total overhaul of the Quota Management System and we need a new way to oversee New Zealand’s fisheries.”

Take the survey at: www.legasea.co.nz/crayfishcrisis

Cameras on boats vital LegaSea also called on Minister of Fisheries Stuart Nash to stand firm against industry pressure to dump cameras and electronic monitoring on commercial fishing boats.

It has challenged fishing industry claims that it uses best practice, and that cameras and other forms of

…“Our fisheries are a public resource we all have kaitiakitanga obligations to fulfil”.… monitoring are not required.

Dave Turner, director of Fisheries Management at the Ministry for Primary Industries has been quoted saying, “We estimate that if we found the golden bullet to stop discarding, we would probably put over half of the inshore fleet out of business overnight…”

This admission alone should be enough to continue with the surveillance cameras.

“Fisheries Management can’t quantify the tonnages involved but we suspect they are significant to the point that they are impacting on stocks,” said Turner.

While many boats are run professionally, some fishers operate illegally. They are difficult to catch because offending is easily hidden far out at sea.

LegaSea spokesman Scott Macindoe said: “We know from the ‘Sea Around Us’ research that the industry dumps more fish than it lands.

“We know that the industry was happy to have cameras when they were run by its own privately-held company, and we know that the industry lost the footage recorded in the early trials.

Last year 78% of survey respondents told LegaSea that the size and availability of crayfish in the CRA2 region was either decimated or close to it. There was majority support for a seasonal or total closure to rebuild crayfish stocks. In response to public pressure the then Minister brought a management review forward by a year in an acknowledgement that current management had failed.

“Last year we said the situation was reaching crisis point,” Macindoe said. “Now we have the Ministry conducting a consultation process that gave the public only 18 working days to respond.

“LegaSea and the New Zealand Sport Fishing Council are asking members of the public to tell the Minister just

Gold & Oil: The legacy and menace of the Niagara

By Dave Moran, Editor-at-Large

M

any of you who are regular readers of Dive will be aware of the watery grave of the 159m luxury liner RMS Niagara which was a casualty of mines laid by the German Raider Orion in the Hauraki Gulf during WWII. Her sinking just north of the Mokohinau Islands in the early hours of the 18th June 1940 was the beginning of various successful attempts to salvage most of the over eight tons of gold bullion on board.

For the voyage to Vancouver, Canada, it is conservatively estimated that between 9–15 tons of fuel oil was on board.

The blast from the mine released tons of oil that smothered many kilometres of New Zealand’s North Island coastline, mainly from Whangarei harbour southwards.

It is believed that the amount of oil on the coast was larger than what was deposited on the beaches in the Bay of Plenty when the MV Rena grounded on Astrolabe Reef, south of the city of Tauranga on 5th October 2011.

Interestingly, you can still find remains of Niagara’s oil along the coast today!

On the 10th February 2018 at the Mangawhai Artists Gallery, artist Nicola Everett opened to the public her year-long work titled ‘Gold & Oil – The Legacy and Menace of the Niagara’.

Nicole Everett proudly presents the truth of what an oil release will do to the living environment

Her obvious passion and commitment to bring to life what occurred 78 years ago off the coast of Mangawhai and the possible environmental ticking time bomb within the wreck can only be loudly applauded.

Her work is stunningly creative and her message to her local community and the New Zealand Government was very clear! We need to act now, not wait until we have to clean up the suffocating oil deposited along our coast.

Her collection of woodblock and collagraphic prints tell the story of the mines being laid, Niagara striking

the mine and sinking, as well as the recovery of the gold and the death of marine and bird life as the result of the oil that was released at the sinking. The artwork that made a strong statement to those who attended was a visual representation of what you could expect from a new release of oil from the wreck.

Hanging from the ceiling over a patch of oil-impregnated sand were the real remains of birds and fish covered in black oil!

Nicola is creative enough to know she needed something that really confronts people in an artistic form of what may happen.

delivered; Mike Lee the Waitemata and Gulf Ward Councillor, and Belinda Vernon from Maritime New Zealand.

Belinda Vernon from Maritime New Zealand explaining it’s all under control

Over a period of a year she had collected dead sea birds and fish skeletons from the shoreline. She then slowly dried these remains in an oven and then coated them in black bitumen which represented the Niagara’s thick smothering bunker oil.

This very visual artwork clearly shows Nicola’s commitment to awakening people’s awareness of the results of an oil spill.

Guests included Kaipara’s deputy mayor, Peter Wethey and author Keith Gordon, whose book, Deep Water Gold, details the history of the Niagara’s sinking, the gold recovery and the subsequent first dives by remote operated vehicles (ROVs), followed by the first modern day technical mixed gas divers exploring the wreck in 120 metres of water.

Two contrasting speeches were

Mike Lee is absolutely passionate about the Gulf’s marine environment and has actively been notifying Government departments, as Keith Gordon has also over many years, re the necessity to survey the fuel tanks’ condition and the amount of fuel oil remaining in the wreck. This means being able to evaluate the possible environmental hazard that the ship’s oil represents.

The response to their warnings have largely been ignored by Government departments.

Belinda Vernon’s speech for me, and I’m sure others in the gathering, made it clear just how much Maritime New Zealand have their heads in the sand. Oil-free sand, of course! We were informed that they are fully capable and prepared to take care of any major oil spill from the wreck! Well, unless Maritime New Zealand has invested millions of dollars in vessels capable of containing and removing the oil since the Rena disaster, I would say “you must be dreaming!”

I got the impression they are fully aware of the situation but just want it to go away. Why? My guess is money!

There is a realisation that what needs to be done in the first instance is a non-intrusive investigation of the ship’s fuel tanks to calculate how much oil remains.

Councillor Mike Lee expresses his concerns re the possible environmental risk that the wreck represents This can most likely be done with a combination of ROVs and divers.

Once this is done, the Government will know 100% how big the environmental threat is. What we do know 100% is the wreck is steadily decaying and it is not a matter of WILL the oil be released but WHEN. Let’s hope the Government heeds the warnings and advice from experts and opens its cheque book to have the required investigations done.

As we go to press I understand that Conservation Minister the Honourable Eugenie Sage is considering a meeting with Mike Lee & Keith Gordon.

The oil’s time bomb is ticking 24/7.

Freediving depth champs celebrate with records, and inclusive community

P

eople say freediving is about inward power, discipline and control, and this was acutely evident at Lake Taupo during the 2018 Freediving New Zealand Depth Nationals in March.

Both competitive and recreational grade freedivers took part in the three day competition. Many were hoping to walk away with a strong international ranking to take to future competitions.

Others, like New Zealander Ryan Hansen, are newer to competitive freediving, and though competing in the same disciplines the rules are more relaxed; they are after the experience without too much pressure.

Ryan said: “Having never been to a freediving competition before, going to the depth nationals was quite daunting. However as soon as I arrived I was welcomed and put at ease. The atmosphere was supportive throughout and I learned heaps. I will definitely be back next year.”

The stage set this year was at Lake Taupo boasting fresh water visibility around 15 metres and 19 degree C temperatures. The boat was anchored between Motutaiko Island and Moutere Bay to provide shelter from all but the worst weather.

Competitors could enter up to

three disciplines all completed with a single breath of air:

…the truly great thing about competitions such as this is the sense of community…

FIM – Free Immersion. You can use the rope to propel yourself down/ up.

CWT – Constant Weight, allowing the use of fins, and you must maintain a constant weight for the duration of your dive.

CNF – Constant Weight without fins, with a constant weight and no fins.

Competitors could choose a different discipline every day, or focus on one and submit the best for their final result. You are required to announce the discipline of your dive and nominate the depth you are attempting to reach.

Day One saw almost all competitors perform faultless dives including a National Record for Zimbabwe claimed by Matthew Woods in the Constant Weight No Fins discipline.

Tania Rounthwaite, the only female competing, was amongst the most successful, reaching a depth of 41 metres in Free Immersion.

Day Two and the judges again witnessed several strong performances.

Competition grade competitor Phil Clayton had another successful day with a dive to 55 metres in the Constant Weight discipline.

“I’m really pleased to have been successful again after missing out for a couple of years due to injury.

I love the national freediving competitions, especially the depth nationals, catching up with freediving friends from all around the country.”

Competition organiser Nick Rhodes believes that while it is incredible to see the competitors’ perform, the truly great part about competitions such as this is the sense of community.

“We have freedivers from different parts of the world, and completely different backgrounds, all here with a shared passion for the sport,” he said.

“For a sport that requires you to turn inward for strength while diving, there’s a real community vibe at competitions like this.”

PADI Regional Manager, Jen Clent, agreed. “In freediving, rather than competitors feeling like they’re competing against one another, there’s a sense they are competing against themselves,” she said.

…In freediving, rather than competitors feeling like they’re competing against one another, there’s a sense they are competing against themselves…

Jack Hamilton being congratulated by fellow Auckland Freediving Club members, Anthony Hafoka and Nicky Toothill of the Safety Team on his 40m FIM dive.

“It is so great to see everyone sharing one another’s successes and just as strongly, the disappointment of an early turn or a red card.

“It’s really exciting to see the growth of the sport here, both competitively and recreationally, and to play a part in training more PADI Freedivers to dive safely.”

At the end of the event, first time competitor, Bryan Bailey said: "Competing was a huge amount of fun, and watching for the first time how a freediving competition was run was an education and enjoyable. I was able to put my PADI Freediving training into practice from pre dive mental rehearsal through to good technique, even reaching a PB on my CNF dive.”

Bryan Bailey smiling to the audience having had another white card for his last dive of the competition 30m FIM.

The months of planning and organisation for the three day event paid off with a smooth run helped by having an experienced safety and medic team onsite.

Head of safety Gemma O’Brien said: “We conducted many hands-on training sessions prior to the competition to ensure we were in the best form to respond to all scenarios. It was also great to see women represented in all aspects of the competition, from competitor to judge and the safety team”.

Successful dives ranged from six to 55 metres across both competition and recreational grades; the competition welcomes all levels of diver, and with the rapid growth of freediving, it’s only natural more athletes will join the community of passionate freedivers. www.freediving.co.nz/freedivingnew-zealand-depth-nationals-2018 https://tinyurl.com/ydc937fs

igures for the first 10 months of 2017 show the Solomon Islands have enjoyed the best year ever for tourism numbers.

The islands attracted 21,087 international visitors in the period, 13.4% more than in 2016.

While 39% of all visitors are from Australia, the Solomon Islands Visitors Bureau (SIVB) is delighted with the ever-growing number of Kiwi arrivals which increased by over 12% for the period.

SIVB CEO, Josefa ‘Jo’ Tuamoto released the figures at a luncheon reception in Auckland in March.

He said Kiwi numbers were still relatively low, but their considerable effort in 2017 was starting to pay off.

“Connecting flight schedules from Auckland to Honiara via Brisbane have never been better,” Mr Tuamoto said. And later this year Solomon Airlines will commences a direct Brisbane-Honiara-Munda schedule, thanks largely to the support of the New Zealand government which has played a major role in bringing Munda Airport up to international flight standard.

“This will have a major impact for tourism in our Western Province and particularly Munda, Gizo and the Marovo Lagoon, Mr Tuamoto said.

“Add to that 2018 is the year of festivals in the Solomon Islands and New Zealanders visiting our Hapi Isles will be able to experience some of the most colourful and unique cultural celebrations to take place anywhere in the world.”

As well as diving events these include spear-throwing and shell money festivals, the Roviana Lagoon Festival, fishing, and cooking events.

The biggest event will be the Solomon Islands hosting of the Melanesian festival of Arts and Culture in July over two weeks.

“Add to that our world-class diving and surfing, some of the best sports fishing to be had anywhere in the world, our amazing WWII history and a unique living culture, there can be absolutely no doubt whatsoever that the place to be in 2018 is the Solomon Islands,” Mr Tuamoto said. www.visitsolomons.com.sb

Tara Oceans expedition discovers over 100 million genes from the marine world

T

he Tara Oceans expedition (2009-2013) has collected plankton samples from the world's oceans and the creation of catalogues of species and genes on a scale never before undertaken.

And two articles just published in the journal Nature Communications, (22 and 25 January 2018) explore the role of the genes present in the plankton.

Teams from the CEA, CNRS (French National Centre for Scientific Research), EMBL (European Molecular Biology Laboratory) and the French graduate school ENS, among others, have analysed the expression of over 100 million genes belonging to these complex organisms, from microscopic algae to small planktonic animals.

cycles essential for the survival of organisms, including our own.

Made up of millions of different species, the complexity of plankton presents a challenge for the understanding of these flows of matter and energy on which all terrestrial life depends.

Largest gene catalogue

To address the challenge the researchers at the ‘Genoscope’ have created the largest gene catalogue ever compiled for a planetary ecosystem comprising 117 million different sequences created by isolating the genes expressed in over 400 samples collected during the expedition.

Half of the genes found were previously unknown, indicating that the ocean, a marvellous breeding ground of biodiversity, harbours an enormous potential of genetic functions awaiting discovery.

Plankton is made up of very different organisms, the most simple of which (bacteria, viruses) are starting to be genetically recognised. More complex organisms such as algae, parasites or microscopic animals are far less known, even though they represent the vast majority of ocean species.

We depend on it

Plankton, which is the basis of the oceanic food chain, constitutes the largest ecosystem on the planet, and ensures the proper functioning of the biogeochemical

Individual cells were sampled and preserved during the expedition, with their DNA sequenced using 'single-cell' genomics methods.

Consequently, it has been possible to attribute numerous genes to very tiny organisms (less than 20 micrometres) feeding off algae and bacteria, and forming a fundamental intermediary stage in the food chain. This analysis has revealed a diversity of unexpected functions, and is an indicator of the specialisation within this compartment of the plankton.

How the oceans work?

They found that genes express themselves very differently depending on the water temperature or the concentration of nutrients in the oceanic areas studied.

Enormous variation

organisms in the environment but which, for the moment, are impossible to cultivate.

The massive DNA sequencing has enabled the observation of genes in specific ecological conditions, for example, to demonstrate that numerous organisms use different genetic responses depending on the concentration of iron in the environment and to determine the genes involved.

Role of millions of genes unknown

The study reveals the biological functions of half of the catalogue of genes obtained remains unknown, and it appears these genes express themselves first and foremost in a small number of environmental conditions.

Which genes for which life functions?

In a second article, the Tara Oceans researchers characterise the genomes of several major

It seems these small organisms are more complex than the bacteria that form most of the oceanic plankton which is only beginning to be identified. The research opens up numerous opportunities to understand oceanic ecology with the help of sentinel genes. For example the research makes it possible to study the major biogeochemical processes of the ocean based on the expression of these markers. As a consequence an understanding of the evolutionary and ecological mechanisms of the ocean ecosystem now seems within reach.

The upshot is the Tara Oceans Expedition is providing major elements that describe the role of the ocean as the global climate system or 'machine'. But in order to connect these oceanic genes to global physical phenomena such as the climate, researchers still need to understand under which conditions genes will express themselves, and to which organisms they belong. The horizon is still opening up. www.embl.de/tara-oceans/start/

Wakatobi's coral kingdom The story behind the pristine and protected reefs

S

ome know Wakatobi as a luxury dive resort while others refer to it as a region. It is both, but that wasn't always the case.

A Swiss national Lorenz Mäder spent years searching the Indo-Pacific for just the right place to build his dream resort. When he came across a small island in the Tukang Besi archipelago of Indonesia’s Banda Sea he knew he'd found the place. The surrounding reefs were among the most dramatic and fecund he'd ever seen, and just inshore, there was a white-sand beach fronting a coconut

palm grove. Here in 1995 Lorenz built his dive lodge in the style of a local Indonesian longhouse. He named his dive outpost Wakatobi, a word created by taking the first two letters of the four largest islands in the archipelago: Wangi-Wangi, Kaledupa, Tomia, and Binongko.

Ocean were falling victim to destructive fishing practices such as netting and dynamiting. Rather than quietly sitting by and hoping the local fishermen didn't damage the reefs, Lorenz negotiated an agreement designating a six kilometre section as a no-fishing zone in exchange for lease payments made directly to 17 local villages. This was the beginning of the Collaborative Reef Conservation Programme which has since been expanded to cover 20 km of reef, won numerous awards, and become a model for proactive private sector conservation.

Even as construction began, he was working on a plan that would ensure the future health of the reefs he'd come to love.

Negotiating for conservation At the time, areas of the Indian

… In 2002 the Indonesian government expanded the area … to create the Wakatobi National Park encompassing an expansive 1.39 million hectares of the Tukang Besi island group…

services, private beachfront dinners and a range of water sports and land-based activities.

A fleet of custom (21m/70ft) dive boats depart daily to more than 40 premier sites within the resort's private marine sanctuary where underwater landscapes range from shallow reef tops to dramatic walls and pinnacles covered in luxuriant growths of sponges, and hard and soft corals. These sites are home to thousands of fish species and invertebrates. In fact, the region is known as the most bio-diverse marine environment on the planet.

Rich diversity Divers and snorkelers can experience this rich diversity right off the resort's beach - Wakatobi's House Reef has been named the world's best shore dive - and it can be accessed day and night. The reef line transitions from grass beds to a coral wall just 80m from shore stretching more than a kilometre east and west.

Many guests have spent entire days exploring the House Reef, making treasured finds such as ghost pipefish, leaf scorpionfish, broadclub cuttlefish, six species of clownfish, and a plethora of unique marine

creatures just metres from the resort jetty.

…Wakatobi's House Reef has been named the world's best shore dive…

Lorenz's vision for Wakatobi not only set a precedent for private sector conservation initiatives, it set broader plans in motion, and actually changed the map. In 2002 the Indonesian government expanded the area created by the resort's conservation programme to create the Wakatobi National Park encompassing an expansive 1.39 million hectares of the Tukang Besi island group. Less than a year later these islands became an autonomous region and in the

process chose to adopt a new name: Wakatobi. In 2005 UNESCO listed the Wakatobi National Park as a tentative World Heritage Site which, in 2012, was eventually added to the World Network of Biosphere Reserves.

Many see Lorenz as a visionary and forward thinker who initiated one of the world's largest privately-funded and managed marine protected areas. But he often attributes his motives to a more pragmatic goal.

As he tells it, “You can’t pack up and move your resort when the diving is no longer good. So it’s better to do what you can to protect it to enjoy it now and in the future.”

Stingray city Return of the ‘annual’ ray aggregation Story and images Dave Abbott

Short-tail rays reach a massive size and often come extremely close to divers!

T

his summer has seen the return of the famous Northern Arch stingray aggregation at the Poor Knights Islands, a spectacular occurrence that has seen divers flocking to the iconic site.

When it comes to seeing stingrays underwater, it doesn’t get any more impressive than diving with the Northern Arch aggregation, something I last experienced between 1999 and 2001.

The return of the rays after nearly 18-years even made the news, and in contrast to the usual summer media reports of people being 'attacked' (read ‘stepping on them and getting 'spiked'), the coverage this year was all positive.

…The prevalent theory is that this is a meeting place for males and females to find a mate, a sort of speed dating site…

Stingrays are actually mellow creatures that tend to mind their own business, and incidents involving injuries are usually a self-defense reaction to being crowded or stepped on. Underwater, where both animal and diver can see each other, rays are a relatively safe creature to encounter, and getting close to one is usually painless and enjoyable.

28 Dive New Zealand | Dive Pacific

This is a surreal experience drifting through the middle of the narrow 40m deep archway, the silvery surface 20m above, the bottom 20m below and the whole blue space filled from top to bottom with large black stingrays stacked layer upon layer like squadrons of stealth bombers gliding back and forth.

Why do they congregate there?

The prevalent theory is that it is a meeting place for male and female rays to find a mate, a sort of speed

dating site! This is backed up by the number of females we see with fresh mating scars, scrapes and bite marks on their wings. Strangely though, despite diving in the Arch a lot over the peak years, and even doing several night dives hoping to film rays mating, I never saw a pair in the act. I did notice however that the rays dispersed out from the Arch at night, so perhaps mating happens out over the deep sand or reef terrain.

Interestingly during mating season the teeth of mature male stingrays change shape and become sharper to aid in gripping the females during the act of copulation, a clever adaptation for a creature built like a slippery frisbee.

The closest I came to seeing rays mate was while filming for ‘Our Big Blue Backyard’ in 2014 when a male was attempting to mate with an unwilling and bad-tempered female.

After being rejected the frustrated male then swam over and rubbed up against me until he realized his mistake…luckily for me!

In the peak year, 1999, I witnessed upward of 70 rays stacked in the Arch on days with a good current; the summers of 2000 and 2001 were

…During mating season the teeth of mature male stingrays change shape and become sharper to aid in gripping the females during the act of copulation… also big stingray years. After 2001 however the numbers dropped off dramatically to only 10 to 15 rays at a time, then subsequently down to just

5 to 10 on a good day. Until January this year with up to 30 or 40 rays back in the Arch.

There are lots of theories why they have not been around in large numbers for the past 18 years. One of the favourites is that Orca scared them away after several occasions during 2001 where Orca stopped by

the Poor Knights to feed on them.

They definitely left a few scared rays and a lot of ‘ray apple cores.’

But undermining this theory is that they returned to normal numbers in subsequent years everywhere else around the islands, other than in the Northern Arch. I think it is a safe bet Orca have hunted rays around

Encounter with an extremely rare white ray (not an albino) in Northern Arch nearly 20 years ago

the ‘Knights on and off for a very long time, and the sporadic times they pass through the reserve is not enough evidence to say they drove the rays away for nearly 20 years.

A more likely-factor is the disturbance caused by concentrated diver numbers visiting Northern Arch to dive with them during their aggregation period; it doesn’t take many divers blowing bubbles to turn the archway into a 40m deep spa pool with a bubble curtain from top to bottom! The rays react to bubbles quite strongly tending to move out of the arch until the bubbles thin out again. So it is possible that after a few years of this they sought somewhere else to meet up.

…the whole blue space filled from top to bottom with large black stingrays stacked layer upon layer…

Naturally with the stingray aggregation such a spectacular sight it is a major attraction for divers to the Poor Knights – myself included! It’s an event none of us want to miss, so implementing a few simple measures to minimize ‘diver disturbance’ at this one, specific dive site would help ensure the rays continue to come back year after year for us divers to enjoy.

Perhaps it’s worth trying things like spreading out the timing of dive boats at the ‘Arch so there is an hour or so between dives to give the rays some ‘alone time’; encouraging divers to hang in

Long-tail rays are the other common species seen at the Poor Knights and are generally seen on sandy patches in ones and twos

the archway entrances rather than right in the middle of the Arch; suggesting divers do this particular dive in small groups, and making people aware that freediving/ snorkeling with the rays can be just as spectacular as scuba diving with them. Actually it can be a more interactive experience than on scuba as the rays barely move aside for divers who are not blowing bubbles.

Something I filmed back in1999 and 2000 and haven’t seen in this latest recurrence of the stingray aggregation at Northern Arch are the two pure white rays that used to occasionally show up amongst all the regular dark stingrays – a surreal sight! I often wonder what happened to them and whether we will ever have another white ray show up at the ‘Knights…obviously they are an extremely rare morph.

Black or white, I’m crossing my fingers the rays show up in big numbers again next summer!

The rays at Northern Arch are Short tail rays, the largest of the three common ray species in New Zealand at up to 300kg and 2.5M across. They are viviparous meaning they give birth to live young, and feed on a variety of benthic invertebrates - shellfish, crabs etc.

The other two species frequently seen by divers are Eagle rays and Long tailed rays, though there are also a number of other ray species in our waters including Skate, Torpedo (electric) rays, and in the summer months the two visiting pelagic ray species, Devil rays and Manta rays.

Tourism Fiji moves to revitalise its dive tourism Story and photos by Mike Scotland

My buddy, Laura poses near the mast of the wreck of the Tasu Two off Waidroka resort

L

ast month I was lucky to be invited to sample seven resorts in a wonderful whirlwind tour of diving and resort living.

Our group of 11 from New Zealand, Australia, Singapore, Hong Kong and Germany met in Nadi to head off on the massive Captain Cook cruise boat early on Day One. They run four, seven and 11 day cruises with one or two dives a day. The 11 day cruise heads east to the Lau group and looks like a grand adventure!

The golden dreams of Voli Voli Our first dive - Golden Dreams at Voli Voli - was with Ra divers on the north side of Fiji and we were promised five Ghost Pipe Fish but got lucky and found eight, including one of the rare Hairy Robust Ghost Pipe fish.

Voli Voli, owned by the Darling family from Christchurch, is being rebuilt to an even higher standard after cyclone Winston hit it, with more luxury family units and accommodation catering for groups of up to six in total privacy and luxury. The gardens on each Vale are very beautiful. Nick, the manager, says they are still celebrating their Excellence in Tourism award for quality accommodation.

Dreams. It’s a real knockout dive with swim throughs and caverns and walls of soft coral. Even with overcast light presenting a challenge, these stunning soft coral gardens were hypnotic; so colourful and attractive. In full sunshine this is an underwater photographer’s paradise.

In the morning we dived on Rob’s Rock, and while, Gerldine and the author at the new reception at Voli Voli thankfully, I am not me was the Pygmy Sea Horse, especially OCD, there were Hippocampus severnsi, found by our fish here in the many millions. dive guide.

In the morning we set off for the famous Mellow Yellow dive site with its stunning coral gardens and coral windows and where, nearby at Chile, I found a coral Window of Dreams.

For keen underwater photographers, Chile is a dive to capture those stunning model photos. It has so much colour and fish life, a vivid reminder of the incredible underwater panoramas Fiji is famous for.

These reefs are so beautiful and photogenic.

Wananavu Resort We took the bus to Wananavu Resort just a few kilometres away, a lovely garden resort in the shelter of a bay. Without drawing a breath, we headed out for a dive. The first was Amazing Maze, west of Nanuya Island and not far from Golden

The Pearl Resort Pearl Resort is just a few kilometres along the road, and here we stayed in the brand new wing. Sheer luxury!

Outside is a massive metal sculpture of a giant Bird of Paradise about four metres tall and holding a pearl. I thought it one of the most impressive sculptures I have ever seen.

There we dived with Aqua Trek Shark dive in 20m. Everyone liked this one because we had longer bottom time and the chance to have more time up close and personal with loads of Bull Sharks, Lemon Tawny Nurse and Silver Tip sharks. I am a strong advocate of shark feeding as it benefits the sharks as well as educating divers while creating a platform for a lot of invaluable scientific research.

Brandon, the owner, informed us about the individual personalities of the Bulls. One, a timid girl, loves a

pat; another is a surly gruff bovver boy needing constant reprimands.

The dive guides keep the sharks in check constantly and the whole operation is very safe. In fact they have maintained a perfect safety record for more than 18 years.

Waidroka Resort Back on the bus we’re off to Waidroka Resort, a beautiful garden resort with fabulous views on the

South West coast. Lorna and Andy ‘made’ us do an afternoon dive.

Actually the truth is that we begged him to take us out and so they did.

Canadian dive instructor Christine is very positive and enthusiastic and really good at what she does.

Next day we dived the Seven Sister sand the Tasu Two wreck. Again, we were reminded this is an underwater photographer’s paradise. The walls and caverns are simply splendid, filled with whip corals, soft corals and Fan corals - a Disneyland bright cartoon in the raw.

Christine had told us to look out for the jet Black Giant Anglerfish on the Tasu Two wreck which I found almost immediately, so I signalled my buddies to come in for a photo.

The wreck is covered in formations of bright coral, especially on the mast.

Dive Fiesta It was a bit sad washing up the dive gear for the last time. We were off to Denarau for the formal dive fiesta meetings, but we managed to fit in

a PADI Instructors update seminar with New Zealand manager, Deb. The final day was given over to practice speed dating - we interviewed 10 dive resorts on their diving operations, and they gave us their best!

Topping off the trip was a cocktail hour at the Sheraton followed by dinner, a 95 course meal of wonderful Fijian food.

The dive fiesta was a great success, well organised and highly professional. A huge thankyou to Josefa Waivou and Salman Aziz from Tourism Fiji for putting on such a good show.

foam, giving the illusion something important is happening, and more essences to make everything smell and taste nice and clean, so you can imagine emerging from the experience newly born.

Lemme see… Doesn’t look too bad…

www.divenewzealand.com 37

Ah, here’s the place, let me get to it

There may be a little spot down there. Wait…

Good news! Help is standing by!

There are alternatives to this chemical assault for divers!

Frogmen and women can entrust their choppers to cleaner shrimp, in the certain knowledge that these tiny sanitary technicians will make their teeth shine, mopped to perfection. Even places where no toothbrush can reach will not go undetected by the pinhead eyes of these tireless wee helpers.

Moreover the procedure is ecologically sound; it leaves no harmful effluents. And it is absolutely painless and costs nothing. Not a cent.

Dare devil dwarves You have probably seen these cute little critters during dives in tropical waters applying their tiny tools to the teeth of large fish like morays or groupers, without displaying the least hint of fear. They know - if shrimp can be said to ‘know’ anything - that their hosts are very happy with the treatment they get, and never think (if they can ‘think’), that their host might snap at that easy-to-get morsel at their mouths.

For the shrimp a tooth it seems is a tooth. It doesn’t necessarily have to belong to a big fish. As soon as a diver flashes a grin, minus a mouthpiece of course, an eager servant will appear on the scene, attentive and fearless.

Neither does the patient have to worry about the little animal getting lodged in his gullet; they won’t enter those deadly recesses even when working on a fish.

Whenever the diver needs to take a gulp of air, the shrimp will politely move aside, get out of the way, and be right back afterwards.

In the end the result will be a radiant smile, augmented even more by germ-killing seawater.

Scientists should perhaps consider how we might transfer and resettle these useful little helpers in our bathrooms. They are very cheap to maintain and only tickle a bit.

TAHITI

Tahiti, slice of paradise Story and Images by Dave Abbott except where otherwise credited

T

ahiti really is a slice of paradise.

Sculptured mountain peaks draped in lush green jungle fall away to turquoise lagoons so clear it’s hard to believe they have water in them.

Ring reefs separate white sand from the cobalt blue water just outside, the darker shade hinting at the depth of the water even this close to shore. In fact the average ocean depth throughout French Polynesia is 2900m and even the short 16 kilometre passage between Tahiti and Moorea reaches 2000m. Oceanic water so close to shore means whales cruise by in season within sight of the airport, not to mention sharks and other large pelagics.

French Polynesia has 118 islands divided into six archipelagos, most with airstrips and small dive resorts, all with clear water teeming with life, and many, many sharks. The whole of the country is actually a shark sanctuary, the largest

protected area for them in the world, so it is no surprise the diving in Tahiti is some of the best I have ever experienced anywhere.

They have Nitrox fills at all dive centres and good quality equipment available. All the Top Dive staff I met were competent, friendly and laid-back ...one of their Tahitian skippers even played his ukulele for us in the surface intervals!

My first introduction to Tahiti was two years ago while filming for a National Geographic documentary about shark aggregations. On that trip we spent 10 days in Fakarava at one of French Polynesia’s most famous shark diving sites, filming in the Tetamanu Pass where 800 sharks congregate!

The WWII Catalina flying boat was sunk in 1964 on a sand bottom in approximately 15m of water; 55 years later it’s still in great condition.

Just a short swim away from the Catalina is an older wreck, a cargo

schooner largely rotted away, leaving just an eerie timber skeleton like the ribcage of a dinosaur. Ranging between 12 and 25m deep this wreck has good schools of fish around it and even a couple of grumpy-looking resident Stonefish, not something you want to put your hand on by mistake.

I had some unforgettable free-dives with whales off Moorea, both with solo ‘singing’ males, and with females and calves. Humpbacks calves are often very curious and it’s very special to have an animal weighing several tons come over to ‘play’!

There is also some nice reef diving around Moorea with turtles very common. I saw two or three on nearly every dive, and loved the way they peered around like bleary eyed old men that have just woken up.

One of the best dives in Moorea though was the Lemon Shark Hole which, no surprise, is famous for its Lemon sharks. I really enjoyed diving with them; there is something about their twin dorsal fins, cold cat eyes and fixed toothy grin that gives them a sneaky look. Staying behind with the sharks to film while the group went off, I ended up with

Although sorry to leave Moorea I was also excited about what was next on the agenda, flying to Rangiroa in the Tuamoto’s to dive the famous Tiputa Pass with its roaring current.

etting there: Air Tahiti Nui is the national airline and has a direct flight from Auckland G to Papeete which takes 5 hours, just enough to watch a couple of movies and have a nice meal.

My flight with Air Tahiti Nui was one of the best ever: amazing food, super friendly staff, and very roomy comfortable seats. If you fly a lot you know that is a big deal.

One of the great things about Air Tahiti Nui (and a policy I would love to see all airlines adopt) is that on top of the normal baggage allowance, you can check-in an additional dive bag up to 23kg free of charge. This is a huge advantage for dive travellers because, as you may know, keeping dive gear, camera and other equipment under 23kg is next to impossible. The airline also has a partnership with Tahiti's domestic carrier, Air Tahiti, and consequently can offer the best value flights to those smaller islands dive destinations within the archipelago.

This year is the airline's 20th anniversary, and in November they are introducing a new fleet of B787 Dreamliners. I am really looking forward to my next trip to French Polynesia with Air Tahiti Nui!

Major Paper Nautilus invasion captures photographer

ack in the seventies and armed with a commission from National Geographic I met a squadron of Paper Nautilus swimming in a cul de sac by the Northern Arch (at the Poor Knights). They just started to wobble and didn’t flee. Others, at the Pinnacles, were nestled among the rocks, squirting babies out of their syphons. I had a camera orgy. (see images on these pages).

I began taking undersea photos with a Rolleimarin in the late fifties up in New Caledonia. Today my ancient, 40-odd year old image archive consists of two and a quarter inches square (6x6 cm) pictures taken on something we called 'film.' I used an expensive Rolleiflex twin lens reflex camera in a tough and heavy Hans Hass Rolleimarin housing made of thick metal and I had to crank the film forward after each shot.

On each dive, and I worked to around 200 feet, I could expose only one dozen images. I lit them by exploding magnesium wire coiled

Christmas Island A gift that keeps on giving for divers

Y

our first sight of Christmas Island will likely be from the plane - steep volcanic slopes bedecked with lush green foliage rising from a turquoise sea. You can tell it’s going to be special even from this height, but it’s at sea level you’ll quickly find the wildlife and the scenery, above and below water, is something else again.

While Christmas Island is famous for the mass migration of millions of red land crabs moving en masse from the forest to the ocean once a year it has plenty of other marine action to sink your claws into.

Christmas Island is the top of an extinct, steep sided volcano that rises 6,000m from the sea floor located 360km south of Java in the Indian Ocean, 10° south of the equator, with abundant sunshine and nutrient-rich up-wellings. Steep-sided walls are covered in pristine coral reefs down to 20 to 30m where great gorgonian sea fans take over.

Conditions like this are perfect for all kinds of fish; from the smallest to the

48 Dive New Zealand | Dive Pacific

largest, the whale shark. Christmas Island boasts about 650 identified species.

…On the near-vertical walls, the fusiliers stream up and down in search of plankton, and in the pocillopora coral heads, humbugs and hawkfish play hide and seek with divers…

The coral reefs are home to great shoals of herbivores, and parrotfish, surgeons and unicornfish working their way along the corals on every dive. On the near-vertical walls, the fusiliers stream up and down in search of plankton, and in the pocillopora coral heads, humbugs and hawkfish play hide and seek with divers.

Dive sites are all the way around the island; not all are steep walls. Some bays have shallow reefs sloping down to the drop-off. In sheltered areas feather stars congregate creating small and colourful meadows, and it’s here that turtles are often found

resting. Giant morays hiding amongst the corals and rocks keep watch, as wrasse, rabbitfish and titan triggers cruise by.

Christmas Island has its share of caverns and caves easily explored by divers who can surface inside the caverns to see great stalactites hanging above them.

There is no urban pollution from the island; being 300km from any neighbour means the waters are exceptionally clear. It is often possible to see reef sharks and eagle rays patrolling 20m below.

Being steep-sided allows deep water pelagics to come in close to the shoreline where divers are often treated to some exceptional, though often brief, encounters with ocean going manta rays, scalloped Hammerhead sharks and whale sharks. This occurs particularly towards the end of the annual red crab migration when the abundance of crab larvae in the water attracts them to the island.

At the surface, the local pod of spinner

dolphins seem to recognise the sound of the dive boat’s engine and will come over to play for a while in its bow wave, usually hanging around long enough for you to grab a mask and snorkel and join them in the water.

Even snorkelling from the beach in Flying Fish Cove it’s possible to count 60 species of marine life in 60 minutes.

…Being steep-sided allows deep water pelagics to come in close to where divers are often treated to some exceptional encounters with ocean going manta rays, scalloped Hammerhead sharks and whale sharks…

Christmas Island can be dived year round as the waters are warm (26-29°C), there’s very little current, and there’s always a lee shore somewhere if the wind is blowing.

Signature dive sites Spend a few days on the island and you are bound to visit these signature dive sites.

Perpendicular Wall Perpendicular Wall falls away almost vertically a few metres from the surface with corals leaning out as far as they can to catch the sunlight.

Large gorgonians extend at right angles to the wall to catch as much as they can from passing currents, in a riot of colour teeming with fusiliers which seem to take great pleasure in vertically schooling up and down the

wall while the other reef fish travel horizontally along it.

The dive starts under an overhang with fantastic sea fans then falls away towards the north-west tip of the island. The wall literally teems with life: great coral and shoals of fish both small and big. Keep your eye out in the blue; whalesharks, hammerheads, reef sharks and other pelagics love

Perpendicular Wall as much as divers!!

Thundercliff Cave In fact there’s more than just one cave; it’s a system of caves you can follow deep inside the island. But most divers visit the first two: a big open chamber with stunning blue light streaming through the entrance; and a second cave beyond and accessible via the first.

Surfacing within the air-filled cavern, stalagmites and stalactites cast silhouettes on the walls. A rocky platform serves as a handy exit point - divers can remove their gear and walk back through the underground cave following a brackish water stream where, after 50m, there’s a pool of water and, turning off the torchlight, a milky way of light is revealed.

Lantern fish create a spectacular light show making it appear as if the night sky is being reflected upside down.

Step into the turquoise water from the beach of the boat ramp, and within a few metres you are surrounded by

pristine coral gardens. Or for a more adventurous dive, drop in at night.

Jump off the end of the jetty, and follow the sand patch out until you hit the drop off. Turn left and work your way along the reef down the drop off to about 18m. After 20 minutes work your way back along the reef until you reach the sandy floor, then turn sharp right towards the shore line, working your way back along the sandy shallows and navigating back to the jetty, which at night, is lit up like airport landing lights to guide you back in.

The grey moray eel ~Gymnothorax nubilus

By Paul Caiger

Moray eels are a very diverse family of fishes found worldwide in tropical and temperate locations, and in New Zealand there have been at least 12 recorded species though only five are common. The grey moray is usually found north of East Cape in New Zealand, and mostly around the offshore islands, indicating its tropical origins. They are also found in the subtropical islands north of the country: the Kermadec, Lord Howe and Norfolk Islands.

The grey moray possesses – a characteristic of all morays – large fanglike (canine) teeth, and a scale less bodies covered in mucus. Of the several rows of teeth, some are hinged to allow them to fold backwards; which can also lock vertical to hold prey trying to escape.

The vicious reputation in grey morays is undeserved - they don’t react unless provoked - and is largely due to their wide gape and exposed teeth. In actuality, the opening and closing of their mouth is required to oxygenate their gills, though to humans this may look like they are baring their fangs aggressively. Their gill openings are reduced to small, hardly visible pores. Like other eels and primitive fishes, the grey morays possess a lengthy, pelagic leptocephalus larval stage. However, little is known about the biology and life history of these eels.

Most morays are nocturnal in behavior though the grey moray is reasonably active during the daytime and is seen far more often out in the open than other species of both morays and other eels in general.

They are also frequently seen draped around kelp and sponges, rather than in holes and crevices like all other morays. The grey is also the

most slender of the morays found in New Zealand.

Grey morays are generally carnivores, mostly eating crustaceans and cephalopods though they will readily eat small, slow or sick fish they can catch, and they are known to be scavengers, also being found in crayfish pots.

Novice diver continues diving despite ear pain

By DAN's Brian Wake Since my very first dive a year and a half ago I've always had trouble equalising my left ear and I can equalise it only by swallowing

O

n my recent trip to Cozumel I was participating in the first dive of a planned seven-dive series over four days. During the descent, I had difficulty equalising, and between 6m-9m I felt pain in my left ear for a few seconds to a minute. I halted my descent and told the divemaster about my problem. I ascended a bit and equalised my ear pressure by swallowing. When my ear felt normal, I continued my descent.

Photo credit: Stephen Fink

56 Dive New Zealand | Dive Pacific

At about 4.5m I experienced the same problem again. I stopped, ascended and tried to equalise. Suddenly I heard a loud "explosion" in my left ear followed by strong pain, dizziness and nausea lasting for about one minute.

…Suddenly I heard a loud "explosion" in my left ear followed by strong pain, dizziness and nausea……

Symptoms disappeared almost as suddenly as they appeared, and I completed my dive without problems.

After completing one more dive and returning to shore I started feeling very dizzy; this lasted until the next day. For three days I also had blurred vision when reading. I experienced mild pain in that left ear occasionally during the following days. It felt like I was very drunk.

Immediately after the first dive I told my divemaster about the equalising problem and the symptoms I experienced, but no one suggested that I abstain from diving for a while. I continued diving as scheduled without any other problems. However, the mild pain in my left ear remained until the end of the trip.

I decided to consult a doctor to be sure I could fly back home. He found middle-ear barotrauma and a bacterial infection of my left ear. There was no discharge from the ear. I received one shot of corticosteroid, antibiotics for five days, Advil for pain, nasal decongestant in tablets and nasal spray.

…After completing one more dive and returning to shore I started feeling very dizzy… For three days I also had blurred vision when reading… It felt like I was very drunk…

When I was back home I saw a doctor skilled in dive medicine 16 days after that ear explosion event.

She said some blood was still visible behind the eardrum, but the otitis had healed.

Six weeks later I saw the doctor again, and she declared that my ear was completely healed — no more barotrauma.

She checked my ears, did a couple of tests and told me that I could dive again.

Since then I have dived 14 times in cold water at depths between 7.5m – 20m. I still have some difficulties equalising that ear, which has always been the case, but no recurring of symptoms.

Insights provided by DAN Asia-Pacific Founder, John Lippmann Failure to adequately equalise the ears results in ear barotrauma (pressure injury), which is a common diving injury. This is often apparent by a feeling of pressure, soon followed by pain, during descent, or sometimes ascent.

If the pressure is not equalised, swelling and bleeding of the lining within the ear will occur, which helps to equalise the pressure and relieve the pain, although this can often lead to infection. In some cases, the eardrum can rupture and, in very severe cases, delicate membranes within the inner ear can tear, enabling fluid to leak from the inner ear and creating the potential to damage this delicate organ, possibly affecting hearing and balance.

Bubbles from decompression can also form in or around the inner ear and so disrupt its function - inner ear decompression illness. In addition, a variety of other non-diving-related conditions affecting the ear can cause symptoms in divers during or after a dive.

Signs and symptoms associated with inner ear dysfunction may include hearing loss, vertigo (spinning), dizziness, ringing or other ear sounds (tinnitus), nausea and vomiting. While symptoms of barotrauma vary, rarely does a diver experience a loud explosion as this diver described.

An inner ear barotrauma …Bubbles from or decompression illness decompression can also needs to be managed form in or around the swiftly and appropriinner ear and so disrupt ately to minimise the its function - inner ear potential for permadecompression illness… nent injury. As such, any diver with these signs or symptoms after diving should refrain from any further diving and promptly call a DAN-supported diving emergency hotline (www.danap.org/emergency.php). The doctor or medic will take a thorough history including the dive profile, the mode of equalisation, any equalisation issues, and the time of onset and progression of symptoms so a suitable course of action can be determined.

Who should have dive medicals?

Professor Simon Mitchell. University of Auckland.

Most people who have trained as a recreational diver in recent years probably did not have a diving medical consultation with a doctor prior to their training course. Most would tell you that they completed a health screening questionnaire and if they did not tick yes to any of the questions, they were allowed to continue with their course without further medical input. Some who did answer one of the questions in the affirmative would have had to see a doctor for a more careful look at the potential problem identified by the positive answer.

ensures ongoing health surveillance for aging divers. A diver who starts at the age of 35 could quite conceivably still be diving at 55 having never interacted with the medical system at all over that period. In some people that will be fine, but in some it will not.

Recent research by DAN in America has shown that 28% of diving fatalities have a cardiac event (like a “heart attack”) as the disabling injury. This tends to be true of older divers, and it is worth remembering that the hazards associated with suffering a disabling medical event underwater are much greater than on land. If you are a diver who has not seen your doctor for a while, particularly if you are over 45 (maybe 50 in women) and have risk factors such as high cholesterol, smoking, diabetes, hypertension, or a strong family history of early onset coronary artery disease, then you should see your doctor. Some degree of common sense can be exercised here. For example if

…Recent research by DAN in America has shown that 28% of diving fatalities have a cardiac event (like a ‘heart attack’) as the disabling injury…

you are 53 and ran a marathon last week, then it is extremely unlikely that you have significant heart disease.

In answer to the question about “who should have recreational diving medicals?” I would suggest that someone who answers an entry level screening questionnaire positively is one. Someone returning from a diving related injury will also usually be advised to have diving a diving physician review.

If a new health issue arises during a recreational diving career, then its significance in diving should be discussed with a diving doctor.

Similarly, those of us who age whilst continuing to dive should take note of the increase in risk of coronary artery disease as we get older. If you are over 45 and have risk factors (see above) them it may be wise to undergo a focussed investigation of heart function and electrical activity during exercise.

I lowered the strobe’s power so I would not blow out the subject.”

Alex receives an Ikelite Gift Voucher for NZ$75.

Judges’ Comments: Great sharp focus. What make this image stand out is its lighting effects. The combination of the strobe’s flash bringing out the snapper’s reddish skin tones and the refracted bluish light from the surface and filtered green light in the background. A small amount of cropping off the bottom and the right side would have made it even more impressive.

Novice Highly Commended: Congratulations, Mathew Kempton, NSW, Australia.

Well done Mathew in taking out both categories in the Novice section.

As mentioned above Mathew was enjoying his diving in the waters around the Sipidan Island, Borneo when he decided to check out the amazing colourful symbiotic relationship between an anemone and a clownfish family.

Mathew receives an Ikelite Gift Voucher for NZ$50.

Judges’ Comments: The ‘lighting up’ of the anemone body with a burst of light from a flash provides the anemone image with a very pleasant glow! The darker background really makes the image pop.

We suggest the image could have been improved by cropping it from the bottom and sides so that you don't see the full extent of the anemone. This would also make the three fish the strongest subjects in the image.

Mathew was diving at a location that most divers have on their bucket list; the waters surrounding Sipidan, Mabul and Kapalai islands off the coast of Borneo.

Judges’ Comments: This is a brilliant image and deserves to win. A splendid example of an anemone about to capture its dinner while a clownfish looks on.

One of the judges commented: “Look at the texture differences between the body and the tentacles. The body looks like a bunched-up duvet. Almost comfortable, if it weren't for the close proximity of the stinging tentacles!”

The image could be slightly improved at the time of taking the image by slightly twisting it to the right so that the subjects were not so central.

DIGITALIMAGING Hans Weichselbaum www.digital-image.co.nz

Editing RAW files In the last edition of Dive we looked at the pros and cons of shooting in RAW. Most folks are fine with JPEG files, but professionals and serious amateurs demand the very best. If you read this column you are likely to have a camera with RAW capabilities, and nowadays even the high-end phones let you take RAW images!

However, if you decide to go with RAW you’ll need a RAW converter to translate your shots into image files.

Which platform? Laptop or tablet?

There are plenty of RAW converters around, but I am going to use Adobe Lightroom Mobile for my demonstration. A few issues back we had a brief look at Lightroom, but mainly as a tool for archiving your photo collection, ranking your shots and synchronising your edits between laptop, tablet and phone.

Yes, the latest Lightroom Mobile for tablets and phones can handle your RAW shots, and more and more people are leaving their laptops at home. Adobe has been keen on joining the tablet craze and I want to show you what you can do on that new platform.

However, keep in mind that the desktop/laptop version of Lightroom is far superior, offering you heaps of additional tools. If you make money out of photography, I certainly recommend a laptop with a separate (calibrated) monitor, just to get the colours perfect.

The second issue with tablets and phones is the data transfer from your camera. With wireless photo transfer still rough around the edges, you’ll need to have the right cable to connect your camera. Another problem is the limited memory capacity. RAW files love eating storage space and there’s not much on a tablet or phone. You’ll seriously need to look at cloud storage.

Adobe Lightroom CC for mobile

One of the main benefits of working with RAW files is that they allow you to utilise the entire dynamic range of your camera sensor. The original photo in Image 1 is flat looking and

64 Dive New Zealand | Dive Pacific

Image 1 - Recovering Highlight Detail from a RAW file (Samsung Galaxy S3 Tablet) badly overexposed, taken shortly after sunrise in Rarotonga. There wouldn’t have been much hope for rescue if it was taken as a JPEG, but you’ll be surprised on how much more highlight information one can tease out from a RAW file!

…Yes the latest Lightroom Mobile for tablets and phones can handle your RAW shots, and more and more people are leaving their laptops at home…

When you open a RAW file on your tablet or phone you’ll get lots of options, but we are just going to look at the editing facilities. Lightroom will offer you the following groups for adjustments: Crop / Light / Colour / Effects / Detail / Optics and Geometry. On top of that you can also make local adjustments using a paintbrush or a gradient mask. Most of the tools are self-explanatory and we will only look at the some of the most important ones.

I recommend that you start with the Colour group, nail the colour temperature (if it needs adjusting) and trim the overall colour balance and saturation. It is also a good idea to have the histogram open in front of you while editing (Image 1, top left). It shows you the distribution of dark (on the left) and light areas (on the right) of the photo and how they are populated. You can see the peaks shifting while doing your editing adjustments. The histogram tells you when you start losing shadow or highlight detail. In our case you can clearly see the shadows hitting the wall on the left. This is fine because this shot does not need any shadow detail.

After adjusting the colours you move down to the six sliders you’ll find under the ‘Light’ tab (Image 1). The controls are labelled as: Exposure, Contrast, Highlights, Shadows, Whites and Blacks, and I suggest you’ll go through them in the following order:

1. ‘Exposure’ should be your starting point for the overall tonal adjustment

pher the chance of being more creative. The professionals probably won’t go near them.

2. ‘Whites’ and ‘Blacks’ allow you to establish the brightest and darkest areas

Another powerful tool is the ability of masking part of your image. Image 4 shows you the linear gradient in action on a Galaxy S7 phone. I protected the foreground with a mask to increase the colour saturation of the sky without affecting the beach with the boats. You can also use a circular mask or paint with a brush.

3. A djust the ‘Highlights’ and ‘Shadows’ to your liking 4. U se ‘Contrast’ to optimise the overall contrast.

In this example I pulled the ‘Whites’ slider all the way to the left to recover any detail in the highlights. In addition, I also used the ‘Curves’ command. This is a very powerful tool that allows you to seamlessly adjust the tonality from the darkest shadows to the lightest areas. This tool requires an entire article on its own, but you can learn it quite easily by pulling the whole or part of the curve up and down and see what it does to your photo. Note that you can switch to the individual colour channels; for example, you can enhance the reds in the highlights and the blues in the shadows.

The Effects Tab

Next I want to demonstrate the Effects tab (Image 2). The ‘Clarity’ slider increases the local contrast which comes handy if you want to bring out more detail in an overall flat photo.

…The main beauty of shooting in RAW is that you can confidently utilise the full potential of your camera… they allow you to utilise the entire dynamic range of your camera sensor…

Image 3 - The Presets There are lots of editing options we haven’t touched on.

For example, the sharpening and noise reduction adjustments in the ‘Detail’ tab – these are very important tools and merit an entire article. Then there is the ‘Optics’ tab to enable lens corrections and the ‘Geometry’ section to eliminate distortions.

The main beauty of shooting in RAW is that you can confidently utilise the full potential of your camera. Also keep in mind that the RAW converter does not touch your original files – they are kept pristine; only your adjustments are stored and used to create the photo you like.

And you can come back to your RAW files at any time to produce a different look!

Image 2 - The Effects Tab On the other hand, pulling the ‘Clarity’ slider to the left adds a kind of dreamy look to the image. This is often what you want in a portrait, but it also added a soft touch to my beach photo.

On this tab you’ll also find a ‘Dehaze’ slider and a couple of controls to add an attractive vignette.

Lightroom does offer you a vast choice of presets. Image 3 shows you the ‘Creative’ presets, but there are other groups as well, including black & white options. These are the common filters that give the amateur photogra-

BOOK REVIEW

“From the first nail-biting story of up-close encounters with crocodiles to the last heart-warming description how to make Pecan and Pear Bread by first growing a pear tree, Dining with Divers had me hooked from the first dip,” reports Monica Tindall, Editor of the Yum List.

It's often said that the next best thing to being underwater is being able to talk about it. And there's no better time or place for producing stimulating conversation and wonderful stories than when gathered around a kitchen table sharing good food and wine with a group of like-minded friends.

ADVERTISERS’ INDEX

In Dining with Divers Simon Pridmore and David Strike invite you to join them around their kitchen table to listen to stories and try dishes served up by a gathering of some of the great

Airtec Boatshow NZ DAN FantaSea Inon Nauticam

and the good of the scuba diving world: explorers, record-breakers, innovators, designers, entrepreneurs and raconteurs all compete for your attention and taste buds in this first volume of a unique series of diving story cookbooks.

Simon and David know that divers generally love to eat but they didn’t expect to find so many that had such impressive culinary skills. The dishes their contributing divers propose vary from cookouts to curries, from Thai salad to Flemish stew, from jellied eels to vegan cupcakes - there really is something for everyone.

The book mingles the recipes with personal accounts of underwater adventure ranging from shipwreck discoveries to iceberg exploration and encounters with big marine animals.

Each dive is a delight, and you won’t know whether to keep the book in your kitchen or on the bedside table.
