ried out by the Americans in WWII on February 17-18, 1944. The result of this action was the ultimate demise of the combined Imperial Japanese naval fleets stationed in the calm waters of the lagoon. To explore the resultant multitude of war wrecks is the reason we have journeyed there.

Trukâ&#x20AC;&#x2122;s barrier reef has a circumference of approximately 225 kilometers encompassing some 19 lush, mountainous islands of volcanic origin and consists of some 225 coral shoals/islands and reef structures all comprising just over 1,300 square kilometers. Substantial increase in the local population after the war and the change to a cash-based economy promoted by administrators under the Trust Territory resulted in less reliance on historical subsistence living through farming and cultivation and a dramatic change to one of dependence more on imported food. All the major islands are fringed with mangroves and the higher, fertile islands support a variety of local plants and trees including but not limited to banana, taro, mango, breadfruit, and coconut... all of which supported the indigenous existence augmented by fishing until after the war. Likely inhabited for over 3,000 years, the culture of Truk (now called by its traditional name: Chuuck) enjoyed (or suffered through - depending on your viewpoint) Spanish, English, French, German, Japanese and American administrators. Germany ultimately purchased Truk and Micronesia from the United States by arrangement following the Span-

Then, by a clandestine and controversial pact with Great Britain, Japan seized most of the island groups in 1914 ostensibly to counter German supply routes during the first World War. Japan never looked back and began to militarize the area after being officially mandated control by the League of Nations in 1919 despite strenuous objections from the U.S., Australia and Great Britain. Japan immediately thereafter commenced an intensive policy of immigration to Micronesia to suit their economic and strategic expansion goals and by 1937 Japanese emigrants soon outnumbered the native population of about 50,000.

By the late 1930s, the Imperial Japanese Navy had established the largest fleet anchorage outside of Tokyo Bay at Truk complementing the natural and protected, deep water anchorage with airstrips, seaplane bases, headquarters (including that for Admiral Isoroku Yamamoto, the architect of Pearl Harbor), repair facilities, fuel tank storage farms, two separate troop garrisons with combined complements of around 40,000 men, and all other associated buildings and centers to supply their combined fleets. This despite the 1919 Treaty of Versailles specifically forbidding any militarization of the area. Because the lagoon is approximately 70 kilometres in diameter, and therefore seemingly immune to naval bombardment from enemy ships, plus with limited access through mined passes in the outer reef, it became known as ‘The Gibraltar of the Pacific’. These facilities were to play major roles in the Japanese expansion in the Pacific including the attack on Pearl Harbor on December 7, 1941. With the establishment of this military and fleet center, the Japanese population in Micronesia grew to over 100,000 souls far exceeding the number of locals. This tsunami of ‘foreigners’ changed forever the cultural heritage of Micronesia.

On February 4, 1944 an American reconnaissance flight 6| Seawords

over the lagoon revealed a staggering array of over 60 ships including two fleet aircraft carriers and the Japanese-flag super battleship Musashi among other major capital ships of the Imperial Navy. The Japanese commanders, alerted by this flight, quickly dispatched as many of the warships as possible to nearby Palau realizing that their stronghold might come under imminent attack, the departure of the warships leaving the atoll nearly defenceless. The rest of the fleet made up of mainly transports and supply ships continued unloading to storage facilities ashore. The reconnaissance also showed the American commanders that indeed Truk was a major supply depot and Wing camera of the destruction of the C Lagoon during Operation Hailstone. courtesy of: The National A

anchorage and had to be dealt with to secure Allied control of the area for the ultimate proposed invasion of Japan.

In the early morning hours of February 17, 1944, the American attack on Truk commenced and was code named ‘Operation Hailstone’. Task Force 58 launched over 500 aircraft from five main and four light aircraft carriers, the flag battleship New Jersey, six other battleships, a full complement of cruisers and destroyers and a variety of associated fleet vessels... the first solely aircraft operation of the Pacific campaign.

On February 4, 1944 the U.S. flew a reconnaissance flight over the lagoon Operation Hailstone was a disaster at Truk.

This adds to the complexity of potential efforts at wreck preservation given a subsistence society with such different values and priorities. Additionally, most of the world dive community always has and continues to view Truk as a significant dive destination rather than an important historical site in need of preservation, and this mindset dictates how the wrecks are regarded from the Chuuk government viewpoint... and most particularly, that of world perception. They are a money generating resource. Hampered by overlapping agencies, lack of funds, corruption, and conflicting preferences, historic preservation is an obvious low priority.

It has been 39 years since I last visited Truk as it was then known. Legend has it that the Germans had difficulty pronouncing ‘Chuuk’... its traditional name... and the easier pronunciation ‘Truk’ became the namesake until independence. I was anxious to re-visit the many wrecks I explored in previous years and view them again through the prism of time. My impressions are bittersweet after recalling my first visits to this living history book of a location every year for six years during the mid-1970s writing and photographing for a variety of publications (National Geographic, Skin Diver Magazine, The Cousteau Society, Oceans Magazine, The Smithsonian, and others). The wrecks are clearly showing 74 years of exposure to the marine environment and its elements and associated over exploration/exploitation by literally thousands of divers per year.

note that they are much more corroded than my memory and earlier camera imagery recalls. Typhoons have taken their toll as well as many of the remains closer to the surface have been degraded or totally destroyed. The superstructures of many of the shallower and thus more popular wrecks for diving have collapsed in on themselves since my last visit in 1979 and the corrosive nature of the underwater marine environment has turned massive steel plates into thin, brittle and dangerous structures... particularly for penetration dives into the interior of some of these vessels. The sheer popularity of the ‘greatest collection of wrecks in the world’ prompted some dive promoters to remove fragile artifacts from their original resting places within to more easily photographable locations... often damaging the ships structural stability and the artifacts themselves. The results of diver’s bubbles tend to degrade the integrity

Most of all the remains of Japanese sailors have been removed from the wrecks and re-repatriated to Japan... some in the early 70s... most of the rest in 2002.

day. Moorage buoys are in place on most of the wrecks now but more robust and secure anchorages are sorely needed in order to prevent further degradation of these historic artifacts. Estimates suggest anywhere from 3,000 to 6,000 divers per year journey to Chuuk. This equates to nearly 250,000 divers maximum since my last visit and literally millions of hours of dives on the remains since then. Many of the wrecks contain munitions and the locals have been known to remove them for use in dynamite fishing... often to the serious detriment of the marine environment and the wrecks themselves. Of particular interest is the coral growth, which seems to be thriving on most of the wrecks and mimics what the screen of my memory recalls. Interestingly and scientifically significant is the fact that we know almost to This beautiful invertebrate was found on the wires in the radio room of the minute how old the coral is on each of the Kensho Maru.

In the past, often I and my small groups of adventuresome divers were the only ones in the water... anywhere in the lagoon. New since my last visit are three charter, dive, liveaboard vessels working the lagoon each with from 8 to 12 divers per week aboard and literally dozens of smaller outboard craft visiting the wrecks daily from shore-based operators often ferrying up to six to eight divers per boat... every day, often three times per

However, particularly on the shallower wrecks, I note the infestation of massive algae growths on the exteriors... scientific classification - lobophora variegata. I wonder... is this because of the increased effluent being discharged into the lagoon waters from the increase in population

ashore and from the liveaboards, plus the number of shore-based divers impacting the basically closed circuit of the lagoon ecology, or could it be some change in the ocean currents and therefore content entering the various passes into the atoll? Is it because there are still no ‘grazers’ to dine on this growing feast? Spear fishing?

Dynamite fishing? Marine life in the form of coral reef fishes and invertebrates is still abundant and appears to be thriving. But again, no larger creatures were observed save a curious grey reef shark and several spotted eagle rays cruising by just off the perimeter on two of the wrecks. Sea urchins and algae devouring ‘grazers’ were noteworthy in their absence.

As I slowly swim down the interior of a ghostly passageway aboard the Fujikawa Maru, a 433-foot long, 6,983-ton passenger/cargo ship whose keel rests in 120 feet of water, I can’t help but think of what a curious and mysterious blend of life and death are these wrecks. I am driven to reflect on the melancholy nature of death this ship represents despite its abundant and vibrant marine life all around me. Again, I think of how nature is absorbing these instruments of war on the one hand, yet on the other strangely preservLionfish on display. Yamagiri Maru... this is one of the larg- ing them.

obvious deterioration since my last visit, that it will be centuries before the vestiges of manâ&#x20AC;&#x2122;s folly completely disappear from wrecks of the Ghost Fleet in Truk Lagoon. I see the issues of war here slowly fading away, yet the consequences of war will remain long after the tangible has been consumed. I am big on perspective when it comes to my affect on life and how I interact with those around me and this passageway strikes me as eerily macabre, the overriding sensation I experience perhaps because my presence here makes me realize that those who have passed on are Christopher at work imaging on the Kiosumi Maru.

As I exit the passage and slowly swim for the surface I bring with me the rueful memories of what I have seen over the 45 years I have dived here and can only imagine the sights and emotions of those living along this corridor during the attack. I begin to understand what these wrecks truly represent. They are not just to show the individual man merely the consequences of war, but for him to understand and evaluate the choices that can lead to war... or peace. With this knowledge comes awareness and from awareness there can be understanding... and for me with understanding there is hope.

pril 21, 2018 marked the Thirty-Fifth Annual MOP Student Symposium held at the beautiful Windward Community College on O‘ahu. 15 students from campuses on O‘ahu, the Big Island and Maui attended the symposium to present their fascinating skill projects. The symposium consisted of four oral presentation sessions and one poster session. Each student’s presentation was remarkable and inspirational on every level. After everyone had presented, the panel of judges faced the unbelievably difficult decisions on who would win the awards: Best Poster, Best Research, Best Internship, Sherwood Maynard ocean Impact, John P. Craven, PACON and the Anna Toy Ng Award.

The symposium started off with a bang from Professor McCoy’s talk on the discovery of a buried city on the Greek island of Santorini. The newly found city of Akrotiri was buried in ash due to a volcanic explosion 3,600 years ago. Amazingly, the ash preserved the re-

mains of the city and unbelievable discoveries were found in this buried city. Massive vases and sculptures were completely preserved and showed the technological advances of Akrotiri.

Beautiful paintings and intricate art pieces filled the city and walls. There were even paintings of antelope, which Professor McCoy informed us meant that they were importing these animals 3,600 years ago! Jewelry pieces such as earrings were found with astounding designs and beauty. The city was obviously ahead of its time and if anyone needed further proof, a sealed sewer system was found. The ash had preserved food, clothing, tables, plates and much more, allowing geologists to closely study every aspect of Akrotiri.

For the first part of her project, Mckenna evaluated water systems and curing times for the concrete coral modules in the ex situ Coral Restoration Nursery. Her results included two very important findings: coral in an open water system (sandfiltered water, flow-through tank) had greater growth rates than coral in the “closed” watersystem (sand-filtered, UV-sanitized water) and there was no statistical difference between coral grown on cured concrete in seawater for one week vs. one month. In the second part of her project, Lewis assessed the DAR Corals of Opportunity nursery and focused on location and environmental conditions.

Once all approvals had gone through, she began building her tank. She met many setbacks but one that stood out the most was when the 7,200 pound tank began to bow and she had to build a new stand. After the extensive work she put in and her outstanding patience- Nason had built a complete coral system tank. Her tank will be utilized by the public, researchers and students.

She chose brown rice coral because it is a “dominant reef-builder” in Hawai‘i and TLRs play a vital role in disease defense and symbiosis (Stewart). Stewart used mechanisms such as the Basic Local Alignment Search Tool (BLAST) in Genbank and other bioinformatics tools for her studies. These instruments allowed her to gather TLR genes, quality control the sequences and generate phylogenetic trees.

Her results found that there were five TLR genes in the “transcriptome of healthy and Growth Anomaly-afflicted M. capitata colonies”, including TLR1, TLR2, TLR6 and TLR11 (Stewart). She discovered that TLR1 AND TLR2 work together and that TLRs and proteins work in tandem.

for the display of captive bred fish and coral at UH Hilo. Her objectives when she began the renovation were to create a refugium, correct water quality, replace lights, remove scratches on the tank, involve other students and exchange current fish with Hawaiian captive bred fish and coral. Ehlers wanted to house captive bred fish and coral because it is more sustainable than housing wild caught fish and coral. She also wanted to increase algae growth by creating the refugium. Water quality was very important to Ehlers so she used water test kits to test the calcium and alkalinity levels. Her next step was to carefully replace the current lights with blue spectrum lights. Ehlers strategically replaced two bulbs a week to not disturb the marine life in the aquarium. Her restorative efforts resulted in MOP students and coordinators talk story while eating lunch.

Casey Taves gave an outstanding presentation on her experiences as an intern for National Marine Fisheries Service (NMFS) in the Hawaiian Monk Seal Research Program. Taves has been part of the program since June of 2017. Her presentation led us through her daily routine as an intern for NMFS. A usual day is spent receiving emails of Hawaiian monk seal (Monachus schauinslandi) spottings and it is her job to identify the seal in the photograph that was sent to her, and then input that data into the NMFS database. During her photo analysis, Taves must determine the sex of the monk seal, any particular scarring, look for natural bleaching that is unique to each seal and tags that identify the seal and she must keep track of the condition of the seal’s body. Taves found that she has learned an abundance of knowledge and skills throughout her time as an intern.

She improved her time management skills and extended her professional network. She now also has extensive knowledge about monk seals and the island of O‘ahu.

Hawai‘i Maui College - Internship Lorrie Francis-Profio kept the Hawaiian monk seal (Monachus schauinslandi) theme going with her presentation on her extensive work as an intern for NOAA fisheries on Maui, specifically the Hawaiian monk seal recovery program. Lorrie started out volunteering as a monk seal responder which entailed two hours of class training and 20 hours on the field training before she could become an official responder. Some of her duties included taking photos of the seals, identifying marking, scars and behaviors, documenting male and female interactions and finally, setting up seal resting areas. After her work as a responder, she began working the 24 hour hotline.

Lorrie then took her volunteering to the next level when she made her own monk seal family tree which she calls the “Maui County Monk Seal Lineage.”

POSTER PRESENTATIONS

“CONSERVATION AND OUTREACH EFFORTS FOR WAI ‘OPAI TIDE POOLS ON BIG ISLAND, HAWAI‘I” Wheatley Crawley, University of Hawai‘i at Hilo Internship Wheatley Crawley, winner of “The Best Poster” award, really deserved it! Crawley focused on conservation, outreach and education efforts for the coral reefs in the Wai ‘Opae tidepools. Crawley explained that the tidepools are a Marine Life Conservation District (MLCD) but because it is frequently visited, there has been some stress on the reefs due to anthropogenic and environmental factors. Her project consisted of three parts including coral health surveys under Dr. Takabayashi, a conservation poster and an outreach sticker. Crawley surveyed for trematodiasis, bleaching, predation, growth anomalies, pigmentation response, macroalgae and endolithic algae cover. The conservation poster was a group effort, with Crawley receiving help from the Wai ‘Opae Neighborhood Community Committee (WNCC) and volunteers. The poster targeted tide pool etiquette and common species identification.

“SUMMER BY THE SEA PROGRAM, BY THE WAIKīKī AQUARIUM: EDUCATING THE YOUTH & ENSURING OCEAN SAFETY” Shelby Dolim, University of Hawai‘i at Mānoa Internship Shelby Dolim spent her summer educating and working with children to enhance their relationship with the ocean and better their understanding of ocean conservation. Dolim spent a total of 270 hours on her project.

Before she began working with the children, she had to go through lifeguard training and spend many hours researching the subjects that she would be teaching the children. During the program, Dolim worked from 9am to 3pm taking the kids out snorkeling and teaching them about what they had seen, including why it is important to respect marine life and the ocean. At the end of the program, the children were able to identify 20 marine species and give their parents a tour of the Waikīkī Aquarium!

“ASSESSING THE VALUE OF INFORMAL OCEAN EDUCATION WHILE OBTAINING MY DIVE MASTER CERTIFICATION IN HAWAI‘I” Bethany Raypold, Kapi‘olani Community College - Internship Bethany Raypold spread knowledge and awareness of our current ocean issues by working with Waikīkī Dive Center to reach out to scuba divers before their dive trips. Raypold made four infographic slate cards that focused on such topics as turtle conservation, pollution and marine debris, coral bleaching and coral reef and fish identification. Her project consisted of giving educational briefings to divers before their dive trip. Before she gave the briefings, she asked the divers specific questions to get a feel for their knowledge on Bethany Raypold, KCC MOP Student, stands next to her ocean and marine animal conservation.

When Carly Corbisiero’s family came to visit Hawai‘i, she was surprised to find out that while they were snorkeling, they had touched a Hawaiian green sea turtle (Chelonia mydas). Corbisiero was very confused as to why they hadn’t seen the sign specifically saying not touch or disturb the Hawaiian green sea turtles. She decided to go investigate how her family could have missed such an important sign. What she found was a very easy-to-miss sign that lacked boldness and attention grabbing features. Instead of getting frustrated, Corbisiero got motivated and did something about it.

First, Corbisiero decided to make an educational video to show to tourists before they entered Paradise Cove.

This video resulted in every tourist feeling more educated on the laws regarding protected species. She is cur-

DIVE SAFETY

No Buddy, N The Pros & Solo D By: Tyler Phelps, UHH MOP Alumnus

“From birth, man carries the weight of gravity on his shoulders. He is bolted to earth. But man has only to sink beneath the surface and he is free.” These accurate words from Jacques Cousteau are perhaps the most highly quoted in diving because it holds true for so many of us. Diving is a release, an escape from the surface and all the problems we face under normal atmospheric pressure. Most of us are trained to enjoy these undersea therapy sessions with a buddy while others prefer going alone. Diving by oneself or “solo diving” has been around since practically the advent of our sport. With that comes the age old argument: to solo dive or not to solo dive and is solo diving dangerous?

Across trade shows and online community threads you will find ongoing heated debates on the merits of solo diving. By “heated” we mean truly passionate. In one corner of the ring, we have the Buddy Team. Buddy Team consists of divers that are out to convince all the solo divers they need to start diving with a buddy because it’s safer. The Solo Team argue the opposite because you only have to worry about yourself and the training you acquire to become “self reliant” actually makes you safer.

This article offers opinions and evidence on the safety of solo diving that will also be referred to as “self-reliant” diving interchangeably. Is this article your comprehensive guide to everything related to solo diving? Certainly not. As mentioned, the internet is full of arguments lobbying for each team and it would fill an entire Seawords issue to mention them all. Regardless if you are pro-buddy or pro-solo there is one universal truth that applies to everyone that we cannot deny. Diving is supposed to be fun-- that’s why we all do it in the recreational 22| Seawords

creased focus. Have you ever heard of,

Even with considering the pros of solo diving, it is never recommended to push yourself past your level of comfort.

Your buddy is your backup brain and your backup gas supply. We can offset not having a buddy by incorporating some sort of redundant system such cylinders with Y-valves, H-valves, pony bottles or completely independent systems such as in side mount diving. This way if we did have some sort of failure, we have the redundancy to get out of those situations. However unless you have a drone following you underwater, which do exist nowadays, you do not have your backup brain.

During training to become a self-reliant diver, you would learn how to handle emergency situations by yourself, such as running out of gas. Some problems, like getting out of entanglement, are much easier to resolve with a buddy. If you have line caught around your first stage, it’s certainly do-able to free yourself but a buddy with an unobstructed view can help more easily.

However, there is one category of failures that only your buddy can solve. HuMAY 2018 |23

to get in or out of the water. Other examples could include navigation mistakes that perhaps a buddy could have caught.

At the end of the day, solo divers can take care of a lot of problems. Until… you are placed in a situation where your survival is dependent upon your teammates. If you are of an older demographic, you might not be able to recover from an underwater myocardial infarction, a heart attack. Or if you experience Central Nervous Systems (CNS) oxygen toxicity from a high partial pressure of oxygen and suffer a convulsion, your best chance of survival is with your buddy’s help, assuming they have been trained to manage a convulsion. Your value as a buddy and as a diver is limited to your amount of training.

Learning from Solo Diving There are many agencies that now offer self-reliant certification courses due to the high demand. The skills that you would learn in a rescue diver course or self-reliant program will build your confidence and competence even if you are still diving within a team. It is important to be able to take care of yourself in the event that your buddy or teammates aren’t able to. Some pro-solo divers argue that all instructors are in a way “solo divers.” If an instructor is with Solo diver at Ras Mohammad Park.

n ali‘i among cone shells, the abbreviated cone has the special honor of being Hawai‘i’s only indigenous cone shell that reproduces solely in Hawaiian waters, although it has been occasionally found in the Marshall and Line Islands. When the abbreviated cone does reproduce at home in the Hawaiian waters, it lays its eggs under stones where they resemble tiny pieces of sliced bread all lined up in rows.

Small and tubby, this cone shell is less elongated than most of the others in its family and is a distinct, bright yellow color when it is alive. After the animal inside the shell dies, the yellow color is stripped along with the thin periostracum and the shell appears to be a bluish-grey. Both in life and in death the cone has faint spiral bands and spaced out brown dots. The top, thicker end of the cone is coronate (bumpy around the full perimeter like a crown) which may be worn down depending on the age of the shell.

Highly sought after for bracelets and other jewelry, the abbreviated cone can often be spotted on local bangles, as well as in its “puka shell” form - a form of all cone shell spires that get serrated, perforated and worn down while rolling around in the surf. These “puka” (a Hawaiian word meaning “hole”) shells are also often made into bracelets or necklaces.

Like most cone shells, the abbreviated cone is capable of stinging in self-defense - to avoid injury it is best to avoid picking these shells up. Although painful, the toxin of the abbreviated cone is not known to kill humans. Like many other cones, the abbreviated cone uses its venom not only as a defense mechanism, but also to hunt its prey - namely the bristle worm in this cone’s case.n MAY 2018 |25

Pohaikealoha’s poem was chosen from a collection of poems submitted to us by Eric Paul Shaffer, an HCC English Professor, and written by his English 201: Creative Writing class.

As a kid I loved the beach Every aspect of the beach reminded me of my Hawaiian family.

My first sight is always sand gathering in pockets between my toes.

The sand is warm and inviting, Like how my uncles and aunties would be.

I shiver as warmth replaces cold in my body.

The sun is overhead showering me in sunlight.

I can imagine that the sun Watches over me with quiet observance, like how my father would.

The water beyond sand is green and blue.

The green-tinted water curls, rolls over the water’s surface, then hits the sand bank and foams.

The waves could seduce a passing surfer.

The ocean could provide me with food and entertainment, like how my grandmother would.

As a kid I loved the beach, but my perspective changed.

The sand that invited me, held dangers beneath the surface from my knowledge.

Thorns, shards of glass, and coral rocks hid from my sight.

The sun that warmly watched over me, now scorches my skin with a hate-filled stare.

My back reddens at the contact with the sun’s hate.

The ocean that once took care of me, is now a raging tempest seeking vengeance on me.

In the ocean’s domain, I stumble through crashing waves determined to strike me down. n

Marine Entanglement By: Kayla Palmer, UHM MOP Student

A

s the body of a decaying Laysan Albatross lays on the floor of the Northwestern Hawaiian Islands, its revealed stomach displays plastic bottle caps and various other types of plastics. Marine debris and debris ingestion is a global issue affecting 200 species worldwide and 115 in the United States. These 115 species include sea turtles, sea birds, fish and various invertebrates. According to NOAA, the endangered Hawaiian monk seal (Monachus schauinslandi) has a 0.7% rate of marine entanglement which is the highest since 2004. Ingesting marine debris can lead to health issues such as gut blockage, starvation, nutrient deficiency, secondary infection and disease, and immune impairment.

Based on NOAA’S research in the U.S., marine entanglement has occurred in “44 species of sea birds, 13 species of cetaceans, 11 species of pinnipeds, 31 species/taxa of invertebrates, 6 species of sea turtles, and a few fish species.” Even though many marine animals may survive entanglement their injuries such as loss of limbs or deep wound openings may affect their ability to swim, feed, reproduce and can shorten their lifespan.

Before the 1950’s fishing gear and single-use items were manufactured out of biodegradable materials such as hemp rope and paper bags. As the use of plastic became more popular for fishing activities and land-based items, the use of biodegradable products plummeted and marine entanglement and ingestion became a new threat for marine life. Land and ship pollution are the two main contributors to marine debris. During the 1980s the scientific community became increasingly worried about the effect of pollution on sea life, which prompted the start of marine pollution research programs.

Since the early 1800’s through 1900’s Hawaiian monk seals become nearly extinct due to hunting practices. In the 1950’s their population level began increasing but soon declined because of entanglement debris collecting in coral reefs and beaches

which are mostly occupied by monk seals. In effort to protect the Hawaiian monk seal species, efforts have been made to remove debris from the Northwestern Hawaiian Islands.

Cetaceans are most likely to be entangled on their flippers, mouths and tails by fishing gear. Entanglement for pinnipeds usually occurs more frequently from land-based debris rather than fishing gear. The overall data for marine entanglement for cetaceans, sea turtles, pinnipeds and many more species show that juveniles have the highest mortality rate from entanglement because of their playful and curious nature.

“U.S. pinnipeds were generally observed to be entangled around the head and appendages in net fragments, monofilament line, packing straps, rope, and rubber products. While entanglement can affect all age classes, juveniles and subadults appeared to be the most susceptible”, said NOAA in 2000.

Due to the buoyancy of some plastics, many of them get caught in surface currents which leads to a large accumulation of plastic in ocean gyres, which is the same occurrence in the “Great Pacific Garbage Patch.” Surface currents can also cause plastic to collect in convergence zones, which are zones that are high in nutrients which encourages a high food source for a variety marine animals. With plastic mixing in feeding areas, the chance for marine animals ingesting plastic increases. As small organisms or bacteria attach to plastic, animals with a non-selective eating behavior like seabirds, grazing fishes or invertebrates may view marine debris as food and consume the plastic.

Marine mammal research is often limited to stranded, deceased or captured animals so there is little data pertaining to marine ingestion in wild marine mammals.

NOAA states, “Since baleen whales filter extremely large volumes of water while feeding, it is possible that they encounter (and consume) plastic sheets at higher rates than other animals.

There are many health risks associated with consuming debris that can lead to infection and possibly death. Ingested fish hooks are known to pierce the lining of the digestive system causing infection, ulceration, parasitism and inflammation around the area that was wounded. Some marine debris can also contain toxic chemicals “The sheer amount of de- and when consumed by marine mammals can induce bris collecting on beaches, health risks such as cancer, endocrine disruption, imin ocean gyres, and on the mune impairment, and neurological damage. ocean floor suggests that Commenting on how to prevent marine debris pollumany types of marine wild- tion, NOAA concludes that, “Broader policies, both life cannot avoid encoun- national and international, established to reduce the tering with debris,” claims amount of plastic debris entering the oceans will likely NOAA. be the only effective approach moving forward.

ell, fellow surfers--the time has come to officially hang up our winter guns, slather on some extra sunscreen and break out the summer boards. May is traditionally the month where we wave the winter swells goodbye until next October. Even with this year’s strange and abnormal spikes in NPAC swell activity well into April, there is simply no climatological data (neither through NOAA nor through Surfline) to disprove the sad prediction of a winter season passing us by. To heap some more unfortunate news onto that prediction, it appears that both March and April significantly underperformed in terms of SPAC swells this year, suggesting that, if the pattern holds, the South Pacific might join its colder sister in hibernating this month. On the bright side we will all have fewer distractions for final exams. On the downside, it doesn’t look like May 2018 is going to be any better than last year. Perhaps this is the perfect time to go take that Mentawais trip you’ve always wanted (the swell reports coming out of there for May look pristine).

The South Pacific has been severely lacking in powerful activity for a couple of years now, however, we can still plan on some fun, localized surf this summer, and meteorologists do foresee a possible bump in activity this summer compared to the abysmal one last year.

The predicted wind patterns look fairly typical across all of the main Hawaiian Islands for May with a foreseen ENE trade domination throughout most of the month. So if and when we do get some waves, at least they’ll be clean.

As always, be safe, have fun, hope for waves and book that Southern Hemisphere trip (their winter is coming!).

How safe is “reef-safe” sunscreen?

By: Kelsey Loenhorst, UHM MOP Student

H

awai‘i’s lawmakers are currently debating a senate bill proposing a ban on sunscreen containing the chemicals oxybenzone and octinoxate (except under medical prescription). This bill is an attempt to further protect Hawai‘i’s delicate coral reefs which are currently declining at an alarming rate. Oxybenzone and octinoxate are known to contribute to coral bleaching and possibly stunting the growth of juvenile corals; but is sunscreen contamination really the sole driving force behind coral reef decline in Hawai‘i and other coastal areas of the world?

Hawai‘i’s economy runs off of tourism. Tourism is the largest single contributor to the state’s gross domestic product, representing about 21 percent of its entire economy. Breaking a record in 2017, tourism raked in $16.78 billion in visitor spending and another $1.96 billion in generated tax revenue. Hawai‘i’s crystal waters, pristine beaches and lively coral reefs drive this high volume of visitors. Researchers are concerned that this mass amount of tourists are using sunscreens containing oxybenzone and octinoxate, visiting our beaches and therefore greatly affecting the health of Hawai‘i’s coral reefs.

32| Seawords

Other reef scientists are more circumspect about the role of sunscreen chemicals in coral reef destruction due to the lack of research done. The predominant study that reports reef effects of oxybenzone and octinoxate (by Henry Lim in 2016, Sujin Kim in 2014, and C.A Downs in 2014) were conducted in a laboratory setting and do not factor in natural settings on the coral reefs. One study even states that the sample obtained for testing from Hawai‘i’s coral reefs had minimally detectable levels of oxybenzone and octinoxate (Downs 2014). With minimal detectable levels one must consider the other components influencing the health

of our coral reefs.

“Many factors damage coral reefs”, says Jörg Wiedenmann, head of the Coral Reef Laboratory at the University of Southampton, UK. “Banning sunscreen will not solve other problems: for example, temperature anomalies, overfishing, coral predators and the big issue of coastal runoffs that pollute and destroy reefs,” he says. “But if you have places with a high load of tourists going in, it is not unreasonable to stay cautious and say, ‘yes, there may be additive effects.’”

Researchers agree that damage to coral reefs is precipitated by human interaction; but maybe placing a ban on sunscreen in Hawai‘i is distracting from other pressing issues that have a much greater impact.

Some researchers are This ban also brings up some possible health concerns concerned that placing a ban on sunscreens containing for beach-goers. More people are diagnosed with skin oxybenzone and octinoxate will give sunscreen a negative stigma as being environmentally unfriendly – putting the public even more so at risk of skin cancer.

However, switching to reef safe sunscreen is an extremely easy, affordable and accessible step in the right direction in aiding the livelihood of our coral reefs. The Hawai‘i Skin Cancer Coalition members suggest that Hawai‘i’s legislators put forth efforts and resources to utilize the scientific expertise at the University of Hawai‘i to provide sound evidence concerning the effects of sunscreen on coral before placing a ban.

Shipwreck of the Month: Queen Anne’s Revenge By: Jeremy Gasta, UHM MOP Student

P

erhaps there is no ancient ship more famous than that of the Queen Anne’s Revenge, the very ship that feared pirate Blackbeard used to terrorize the seas. Despite the pirate - whose real name was Edward Thatch, or possibly Teach - only owning the ship for six months, it quickly went down in infamy as one of the most feared vessels among 18th century merchants.

The vessel was originally named “La Concorde” and was a French slave ship, transporting captured slaves across the Pacific to the New World. Blackbeard, who had been known to free slaves in the past, was apparently having none of this and captured the ship in November 1717, dropping its French crew and captives off on a nearby island. However, it’s highly doubtful the pirate did this solely out of the goodness of his heart - slave ships at the

time were known for being heavily armed and boasted ample deck space for extra cannons and weapons, meaning La Concorde, soon renamed to Queen Anne’s Revenge, was the perfect property for a pillage-happy pirate. Despite his bloodthirsty reputation, Blackbeard had a habit of using intimidation instead of brute force to convince crews of targeted vessels to give up their possessions, and not much would be more intimidating than a heavily-armed ex-slave ship captained by the area’s most infamous pirate heading in an early seafarer’s direction. This worked out perfectly for Thatch - much of his pirating required little bloodshed of his crew or his targets, yet he was heavily armed should the need arise. And contemporary excavations of the Queen Anne’s Revenge’s remains have shown this to be true, as 30-40 cannons have been uncovered so far, many more

After this incident, BlackAfter appearing as an omen to all seafarers for six beard promptly took several of his crew and possessions months, Thatch’s use of the famed vessel came to an and made away on a smaller vessel, leaving several of his men stranded with the Revenge. However, it’s been proposed Thatch did this intentionally, as he accepted a government pardon soon after and had a short stint of trying to live a peaceful life, not to mention he had a past habit of stranding crew members when he felt things were getting too crowded. However, the siren call of a pirate’s life was apparently too much for Thatch, and almost immediately he was back on the water capturing Navy ships, before being killed in combat that November.

The remains of what was thought to be the Queen Anne’s Revenge were found in 1996 by a private research firm a mile offshore of North Carolina, but it took fifteen years of excavations and rigorous study before its identity was officially confirmed in 2011. Many artifacts have been pulled from the wreckage, including cannons, swords, jewelry, coins, bells, medical supplies, and dining utensils, many of which are on display in North Carolina’s Maritime Museum. Many more artifacts continue to be pulled from the wreck to this day and the ship continues to provide valuable insight into life aboard a pirate vessel. n MAY 2018 |35

he Chinese white dolphin, or Sousa chinensis chinensis, is a subspecies of the Indo-Pacific humpback dolphin (just Sousa chinensis) that resides in the coastal areas of Southern China.

There is some contention as to whether this Chinese variety should truly be considered a subspecies of the larger Indo-Pacific grouping (which has been found throughout Southeast Asia, Australia, and South Af-

Whether a proper subspecies Chinese white dolphins are a coastal species and are or just a population that tends to keep to itself, the Chimost often associated with estuarine environments, where freshwater meets the sea.

The range of the Chinese white population is generally regarded as that of the Pearl River Estuary, which spans several miles along the South China coast, and encompasses Hong Kong, where white dolphin watching has become an important tourist industry. An estimated 2500 dolphins can be found in this population.

Unfortunately, the South China Sea - and especially the area near Hong Kong - is one of the most heavily trafficked ports of the world.

Boat traffic, pollution, and overfishing present great threats to the dolphins living in the area. Toxins from pollutants are especially harmful, as the dolphins’ milk in recent years has been found to be toxic, making newborn calves unable to live very long. Furthermore, the pollutants also affect dolphin reproductive systems, meaning many are unable to have any offspring in the first place. From a ten-year period of 2003-2013, Chinese white dolphins living near Hong Kong dropped from a population of 158 creatures to merely 61. Other threats include overfishing, vessel strikes, and the usage of highly-destructive gillnets.

The animals are medium-sized for dolphins, with adults reaching 6.5 to 11.5 feet in length, and have been recorded living up to forty years old in the wild. They are social, but perhaps not quite as social as other dolphin species, and seem to prefer living in small groups of five or fewer individuals.

Cape Town Water Shortage D

By: Kayla White, UHM MOP Student & Former Seawords Editor ue to environmental degradation and climate change, droughts and water shortages have become more frequent and harsh around the entire world, causing many cities to take drastic measures. Global warming over the last century has created many problems, but one that many people aren’t paying attention to is the extreme weather conditions that changing climate brings. Most of global warming is human-induced, but regardless of the cause, extreme weather events, like heat waves and droughts, are the biggest indicators of the effects of a warming planet.

gling to distribute their water, despite the government’s efforts. Because of their rapidly growing population, most rural areas are left out due to the urban area’s overprivatization. Much of this water shortage is blamed on the government’s poor planning and corruption, and if this continues, the country’s water problem will worsen as the years progress.

A drought in Somalia killed up to 75% of their livestock in November, 2017 because of a harsh El Niño in 2015.

The country suffered two years of poor rainfall that led to widespread crop failure and much of their livestock dying.

come drier. Many scientists predicted that the drought would get very bad, but the government didn’t put anything into action which caused their reservoirs to become increasingly shallow. Now, their water levels are at 22.5% with the last 10% unsuitable for drinking. When the reservoirs reach 13.5%, Day Zero will commence, leaving the entire city under strict regulations.

Although some people think desalinization can be the solution to all of Cape Town’s problems, others understand that this is an expensive process. Desalinization is the removal of salt and minerals from oceanic saltwater to make freshwater. Growing up, we were always told in survival guides that if we boiled a pot of water, it would become safe for drinking; doing this on a large scale for four million people isn’t quite as easy though.

Spaceship Breaks Apart Over South Pacific Ocean orbit it was still able land near the spacecraft graveyard.

On April 1, 2018 debris from a Chinese spaceship named Tiangong-1 scattered thousands of square miles above the South Pacific. Tiangong-1 translates into “heavenly place”, and was launched by China in 2011 as a prototype to discover new ways to operate a space station in Earth’s orbit. According to officials, Tiangong stopped functioning in 2016 and as the 18,000 pound spaceship was pulled by Earth’s gravity causing its acceleration into a lower orbit, researchers were uncertain about its specific landing location. As Tiangong-1 fell farther into the Earth’s orbit, researchers were then able to determine its general landing area between California and Hawai‘i.

Seychelles Swaps Debt for Ocean Conservation

The Seychelles is an island archipelago located in the Indian Ocean, 800 miles off the east coast of Africa that has agreed to a marine conservation plan that will pay for the country’s sovereign debt if government officials protect one third of ocean area. Seychelles depends on fishing and tourism for economic stability, but due to climate change reducing fish populations and the borrowing of finances from other governments has led to the Seychelles’ $400 million national debt. A non-profit organization named Nature Conservatory bought 21 million of the nation’s debt. In exchange, Seychelles will protect 210,00 square kilometers of ocean around Aldabra atoll by 2021. The atoll is a UNESCO World Heritage Site and has very unique marine biodiversity, containing the highest population of leatherback sea turtles (Dermochelys coriacea), endangered sea cows (Sirenia), and is a spawning area for rare fish species. Seychelles has agreed to stop many human activities such as fishing and oil exploration in their marine protected areas.

Some of the Seychelles conservation plans will also include restoring coral reefs, protecting endangered species, restoring mangrove plant populations and Sylvanna Antat, Marine Research Officer with the Seychelles providing sustainable tourism. n National Parks Authority, maps coral reefs.

Actions for the Ocean

GENERATION

BLUE

By: Kayla White, Former Seawords Editor and UHM MOP Student

M

any people spend lots of time in their kitchen and would prefer a home cooked, healthier meal, to a night out at a fast food restaurant. Fast food gets a bad rep for being wrapped in plastic and producing up to 50 percent of the trash found on the streets, but in our kitchen at home we are still producing more waste than we think we are. There are many little things we can do to help eliminate waste when cooking at home so that we can be even more environmentally friendly and “blue-minded.” n

1:

Switch Plastic Bags for Reusable Bags The average family takes home around 1,500 plastic bags in a year and the majority of those are

thrown away and never used again. When in a landfill, they can take anywhere between 15 to 1,000 years to break down but lots of them end up in the ocean and are ingested by marine animals. Many grocery companies have started offering their own line of reusable bags that can be used in the store, or you can bring your own. By bringing reusable bags, we are able to efficiently transport our groceries, while reducing our impact on the environment.

THE OCEAN SPANS OVER 70 PERCENT OF OUR WORLD. It is responsible for regulating temperature, food production, sustaining numerous species, and is a source for inspiration for many people.The ocean gives us so much and it is time for us to return the favor and take actions to make the ocean ecosystem healthy again.

Almost every action that we take affects the ocean in some way. Our everyday choices can be tailored to support a healthy ocean. Here are some examples of green acts that will keep the ocean blue.

2:

Produce is Healthy but the Plastic It Comes in Isn’t The change to reusable grocery bags is becoming more and more common and is helping a greater cause, but the plastic bags we buy our fruits and vegetables in usually are gone unnoticed. Produce bags do the same harm that plastic grocery bags do so to help reduce waste, many companies have started making alternative produce bags that are even better for your fruits and vegetables than the plastic. Some are cotton, netted, or cloth and each have different benefits for different types of produce. With a little research, you can figure out the perfect reusable produce bags for you and continue to reduce your impact on the environment while still enjoying fresh, crisp produce.

3: 4:

Let’s Talk about Leftovers 1.3 billion tons of food is wasted every year, so saving leftovers for dinner another night can greatly reduce waste. As you go to pour your delicious spaghetti dinner into a plastic container that only gets a few uses before getting tossed to the trash can, is it really reducing waste? When packing a lunch for the day, do the sandwich, chips, cookies and fruit all go into plastic bags? These are things we don’t always think about, but thankfully there are many alternatives. Beeswax wrap is a booming product that can help with your leftovers and food storage. It is a piece of cloth covered in beeswax that can seal, wrap, or cover anything and keep it fresh for days, like any plastic bag or saran wrap. Glass containers offer a more sustainable option than the plastic Tupperware for leftovers and help keep your food even fresher.

What the Heck is Composting?

Compost is decomposed organic matter that can be recycled into soil conditioner that is rich in nutrients.

Composting is a sustainable way to help your garden and soil, while reducing landfill waste. Up to one third of landfill waste is made up of compostable materials. By removing this from landfills, it means that we can create more space in our landfills and help them last longer. There are many general rules for composting and most of them are specific to each person’s preference and living accommodations. If a yard is available and you would prefer to keep your compost outside, this works great so that it can easily be transferred to the soil or garden. If in an apartment or small home, composting in the kitchen is an equally beneficial option. This means it is easily accessible when in the kitchen but will need to be transferred to soil when ready.

There are many different options for each person and it is up to you to decide which is best, but in the end, you are still helping eliminate waste while creating a healthier soil environment.

FLASHBACK: MAY 15, 1987

I

By: Jenny Johnson, Editor

n May of 1987, MOP students toured four aquaculture facilities. These four facilities which included a shrimp, bullfrog, tilapia and limu farm, were described as “experimental” at the time. Students were taken to Kahuku, O‘ahu, where all of the facilities were located.

The first stop for MOPers was Marine Culture Enterprises (MCE). This farm is no longer in existence today, but in 1987 MCE was using high-tech farming techniques and machines to pump out mass amounts of shrimp (Penaeus stylirostris). Students witnessed the use of “raceways.” Raceways are tanks that are continuously pumped with saltwater and were thought to be the most efficient and cleanest technique for farming shrimp.

The manager of the hatchery facility, Dee Montgomery, was a former MOP student out of Leeward Community College, who actually did not have a marine biology degree but was thankful for MOP opening doors for her.

In a quote from the 1987 article, Montgomery said, “I feel I owe a lot to the Marine Option Program. It’s great for contacts and experience.” Team members like Montgomery were dedicated to the success of the farm, but eventually it was bought out.

as expensive feed were just as prominent then as they are today. The farm raised a certain type of tilapia but named the fish Hawaiian sunfish in attempt to distance its farm and fish from the negative connotation that tilapia has in Hawai‘i.

Hawai‘i Marine Enterprises (HME), a limu farm, was the last stop of the tour for the 1987 MOPers. HME grew ogo seaweed (Gracilaria parvispora). This limu is still a very popular food in Hawai‘i, especially in poke bowls.

The limu farm was run by co-founders Rick Spencer and Fred Mencher and just one employee. Spencer and Mencher allowed students to sample the limu while at the farm. Spencer explained the demand for ogo at the time, “The demand is more than we can satisfy: about 5,000 pounds a week.” This farm does not exist presently, but thankfully there are still limu farms in Hawai‘i, including Marine Agrifuture that is also located in Kahuku. n

Bullfrog (Rana catesbeiana) farming is likely not something people expect when thinking about Hawai‘i, but in 1987 Malia Crump, owner of the only bullfrog farm on the island, was trying to make bullfrog farming happen. The farm was extremely small, being described as “smaller than the MOP student study center” by Brett Lomont, author of original 1987 article. The small area housed around 5,000 bullfrogs. At the time, the farm had not yet begun making a profit and was still in an experimental stage. Crump was very hopeful for its success, however, today we can see that Rana catesbeiana farming on O‘ahu did not flourish.

Tilapia has been on the minds of many scientists as Oceanic Institute is currently trying to create an affordable feed for tilapia farming. When MOPers visited Oceanic Institute in March of 2018, they were informed the feed prices were “killing” tilapia farmers and causing the practice to barely be profitable, running the risk of losing local tilapia farms. In 1987, MOP students visited Fowler Co. Hawaiian Sunfish Farm and issues such MAY 2018 |45
