NGU is mapping Norway. Our task is to collect, process and impart knowledge about the physical, chemical and mineralogical properties of the country’s bedrock, superficial deposits and groundwater. Since we have been doing this for 156 years, the job should perhaps have been completed?

W OR TH ITS WEIGHT IN GOLD
Norway may prove to be worth its weight in gold. Gold mineralisation may, in fact, arise in zones of crushed rocks in the basement.
The oldest Precambrian basement in Norway is in the north. High-angle shear zones, which may be several kilometres wide, divide the basement into blocks. These zones were formed by plastic deformation of the bedrock deep in the Earthâ€™s crust nearly two billion years ago. The zones eventually reached the surface and stretch for hundreds of kilometres. Mapping shear zones is one of very many tasks in the four-year programme, Mineral Resources in North Norway (MINN), which began in 2011. This government-initiated programme, funded by special, annual grants of 25 million NOK, aims to acquire the basic geophysical, geological and geochemical data that are essential if we are to find and develop the countryâ€™s mineral resources. One reason for this programme is the increasing demand and exploration for resources of metals and minerals worldwide. Technological development is making good headway and densely populated countries in Asia are experiencing strong economic growth. Europe is largely dependent upon importing metals. The Nordic countries are regarded as the most promising area in Europe for future discoveries. In Sweden and Finland, new mines are already operating, existing ones are increasing production and old mines are re-opening. Gold is often closely associated with the development of shear zones. By mapping all the zones running through the basement, scientists believe it should be possible to exclude places where gold is unlikely to be found. The industry would then avoid spending money on unnecessary exploration in barren areas. But geologists face two problems. First and foremost, much of the basement is covered by overthrust sheets of rocks from the Caledonian mountain chain which arose about 425 million years ago. It is therefore not always so easy to locate and investigate these shear zones. The other problem is that when a shear zone is mapped in one place, how can we determine whether it is identical to a zone mapped 100 or 200 kilometres away? The scientists examine the results of geophysical measurements of the bedrock taken from fixedwing aircraft and helicopters. They then carefully study all earlier bedrock mapping before doing fieldwork in the most interesting areas. This is how research and mapping of geological processes are used directly in exploration for mineral resources.

READING THE LANDSCAPE Data acquired by laser scanning in different parts of Norway are provided by the Norwegian Mapping Authority through its cooperation with Norway Digital. Using appropriate software, geologists can remove the vegetation to leave the terrain surface completely free of noise. Smooth surfaces and various formations in the superficial deposits are particularly clearly revealed, as are structures in the bedrock. This enables the scientists to direct their fieldwork at specific problem areas and ignore less important ones, thus enhancing their efficiency in the field. Laser scanning is very useful for mapping and research, and may also have direct socio-economic value. It helps geologists to better identify and demarcate natural resources like gravel and sand, because they stand out with a clear signal in the terrain image. Avalanche courses, alluvial fans and former river channels are examples of features which often are very distinct, and when laser scanning is used it makes no difference if they are in dense forest. The mapping of such landforms helps geologists to understand where avalanches and flood water can go. A wide range of deposits from the Ice Age, like terminal moraines, eskers and drumlins, stand out clearly from the surrounding landscape and show how the ice sheet retreated at the end of the last Ice Age. Many landforms that are distinct in the laser image are so small and diffuse that it would have been impossible to see them on an aerial photograph and perhaps not during fieldwork either. Many places along the Norwegian coast have old, raised shorelines. They are evidence of land uplift and how the sea excavated into earth, sand and clay leaving behind beach ridges and rock incisions which may now be located several tens of kilometres inland from the present coastline. Laser scanning gives geologists an overall view of these old strandlines so that they can distinguish them from one another. In 2013, Quaternary geologists from NGU began mapping the map sheet which covers Kvam, a village severely hit by a flood in May. Over a period of 11 000 years, the river flowing down the branch valley of Veikledalen has built up a large fan of alluvial and flood deposits. Laser scanning can aid scientists in demarcating such deposits more precisely and help them to study how water erodes, transports and deposits enormous quantities of sand, gravel and rocks.

30 year old FF Seisma is still undertaking survey cruises in the fjords.
COMBING THE FJORD Hardly anything characterises Norway more than the long, narrow, deep fjords along the coast. Tourists come from all over the world to get a taste of the fantastic scenic experience you can enjoy in a fjord flanked by precipitous mountains. Nevertheless, they miss most of it, and perhaps the best: the unbelievable underwater scenery and wildlife.
When NGU's research vessel, FF Seisma, sails into a fjord to uncover and survey the landscape beneath the water it is not only with a view to tourism. It is also essential to obtain a thorough knowledge for good management of the natural resources. Commercial life in coastal communities is largely linked to fishing and aquaculture. Six municipalities in the two Astafjords in the southern part of the county of Troms are keen to pave the way for successful commercial life. At the turn of the millennium, these two fjord arms were full of aquaculture plants and the municipal boundaries were an obstruction to developing good plans to use the area jointly. The solution was to draw up a joint municipal land-use plan and pave the way for the aquaculture firms to operate jointly. Some years ago, NGU was commissioned to carry out detailed mapping of the sea floor in these fjords, and later in most of southern Troms. By degrees, as good maps were prepared showing the relationship between the underwater landscape, the bottom sediments and the biology, it became possible to develop the businesses in a more efficient and environmentally friendly manner. Good information was provided on where conditions were favourable for anchoring aquaculture facilities, where the current is strong enough to ensure oxygen for the fish, and where a facility can be located without obstructing other commercial activities such as trawling. The basic marine map was a valuable tool for managing the local resources. The Astafjord project ended in 2012, and the target was achieved. Southern Troms is the best-mapped stretch of coast in the country. The municipal councils and business community have now a valuable tool. The local communities are very enthusiastic to use the knowledge that has become available, and to recruit people to their businesses. To a large extent the key to success has been the local initiative some years ago, and the keenness to press ahead with the Astafjord project. However, an important element has been the effort put in by NGU and its expertise in mapping the sea floor. With its equipment to acquire seismic data, a multibeam echo sounder, sampling gear and video cameras, FF Seisma can go right up to the shoreline in its hunt for knowledge of the sea floor. So far, only a very small part of the shallow Norwegian coast has been mapped. We hope to put this right in the years to come.

HUGIN: This remote controlled underwater vehicle has found bombs and ammunition in Trondheimsfjord.
DUMPED IN DEEP WATER Furthest out in Trondheimsfjord, an underwater dump of ammunition, bombs and wrecked ships lies on the sea floor. Because the dump is so open, there is a potential risk that contaminants will spread in the sea.
Ammunition and other war equipment were dumped in many places in Norwegian fjords after the Second World War. One of these dumps is between Rissa and Agdenes, in the deepest part of Trondheimsfjord, at a depth of more than 600 metres. Frequently, the seabed at such great depths is dominated by soft mud. Things dumped there will thus disappear into the mud and eventually be covered by new deposits. But this is not always the case. In some places, strong currents flow just above the sea floor, and this is the case at the site in Trondheimsfjord. Here, the current is so strong that the sediments are being eroded and removed from the area, and no new sediment is being deposited there. Consequently, the materials dumped there about 65 years ago are still clearly visible on the sea floor. Photographs show large numbers of cylinders, some of which are very rusty and corroded. This means there is a risk that contaminants may disperse into the water. The scientists have acquired extremely clear images of the sediments and objects on the sea floor using HUGIN, a self-propelled autonomous underwater vehicle. The images show that the wartime rubbish lies on the sea floor without being covered by mud. These investigations are part of NGU's efforts to use the best available new technology to map and document geological conditions and processes on the sea floor. This technology will be used to tackle environmental problems, which have wide interest for Norwegian society. The investigations in Trondheimsfjord are part of a cooperative project with the Norwegian University of Science and Technology (NTNU) and the Norwegian Defence Research Establishment, which enables NGU to help develop new technology and methodology that can give still better results. NGU and NTNU plan to study the dump in more detail in 2014. A remote-controlled mini-submarine will be used to obtain new, even more detailed, images and data, and to take samples which can tell us whether undesirable contamination is leaking into the marine environment.

ly say they want data on the superficial deposits and bedrock in their area. This is valuable for finding out where there is a potential for exploiting resources. It is important for coastal municipalities to learn about the geology of the coastal zone. Municipal planners are also keen to obtain information that is relevant for landslides and rock falls so that they can undertake obligatory risk and vulnerability analyses. All this
Just before Christmas 2013, a well sunk in bedrock in Ringsaker, in the county of Hedmark, was recorded as number 80 000 in Norway. Probably more than 150 000 wells for water and groundsource-energy have been drilled on land in Norway. Even more information about subsurface Norway will now be registered and collected in databases.
RIGHT TO THE BOT TOM The subsurface is being used more and more. Many road and railway tunnels are being driven, waste dumps excavated, and sewage plants, various kinds of storage halls, hydroelectric power plants as well as industrial and defence installations are being built. There is a great need for good knowledge of the subsurface, preferably in three dimensions. Vast amounts of drilling data already exist from various kinds of subsurface investigations, including geotechnical drilling in superficial deposits, all the wells and numerous investigations of bedrock quality. The problem is that such data are largely unavailable, because they are in the hands of many different owners and users. NGU, for instance, manages the national groundwater well database as required by the Water Resources Act. Drilling companies have to report all drilling that takes place on land. After the Act became law in 2001, the number of new wells reported has increased greatly. In the last four years alone, 30 000 new ones have been reported. The last one recorded in 2013 was that water well in Hedmark. However, the demands are growing. NGU, in close cooperation with the Norwegian Public Roads Administration, the Norwegian Water Resources and Energy Directorate and Jerbaneverket (the Norwegian agency for railway services), has therefore started to build up a national database for subsurface investigations. This database, with the acronym NADAG, will provide a full overview of investigations that have been carried out. Such facts are of great value to permit the best possible management of land areas, both above and beneath the surface. At the same time, data can be re-used to save society a great deal of money. The first version of the database, containing data from a test area in Oslo, was prepared in 2013. The NADAG database will gradually be expanded with more functions and adjusted to the requirements of the users. The location of the well, the type of drilling, the depth, the name of the company, the date and the report number are minimum information in the database. In some cases, much more data will be available.
