  • Overview of Arctic Fishing

    Traditional fishing in Greenland

    The civilizations of northern Europe commercialized fishing, taking cod and herring in the seas off Norway and European Russia. During the past and recent years the Arctic and the Sub-Arctic was and will be a valuable food production area and has supplied over the years valuable nutrition for the south.

    Historically the Arctic supported the urbanization of the south, providing the cities with oil from whale and shark products that was used for lamp posts, production of soap, and for lubrication of machinery of the industrial revolution.

    Arctic fishermen and whalers of the past are long known for their overfishing and whaling. Oil was a valuable product and in high demand in the beginning of the industrial revolution.

    The cod fisheries in the Canadian Grand Banks became available as soon as the vessels where good enough. Naturally fishing increased with better technology and the when exports were more frequent.

    This even led to over fishing in the Arctic, especially in the Barents Sea and the northern Norwegian Sea, in the second half of the 20th century.

    The fishing fleets in Norway and Russia turned to capelin but déjà vu, the stocks were overharvested in a few years.

    Conservation measures have seen the stocks strengthened but the stock in the Barents Sea has gained ground again.

    Around Iceland, a big fishing nation, the stocks have also collapsed but are not in any danger. Iceland still relies heavily in fishing, but not as much as before.

    Fishing in the Bering Sea has come under scrutiny in recent years because of its potential involvement in the decline in the number of Sea Otters and pinnipeds.

    Traditional racks for the drying of cod

    Historically, fishing for salmon species, herring and halibut have been important.

    Visitors to south-western Alaska need only read the menu if a local restaurant to recognize that salmon and halibut are a source of local pride, and catching of those species are a popular tourist attraction.

    Salmon fishing is also important in the Russian side of the sea as well as for Japanese trawlers.

    In the 1970 and 1980s the fishing of the Walleye Pollock increased dramatically, with annual catches of up to 20 million tones eventually being recorded.

    However catching then dropped sharply n the area, probably because of overfishing and the rise in water temperature.

    Fisheries in the Arctic have changed significantly throughout the history where subsistence based fisheries have been the core value. The catch from the sea has made the Arctic and the Sub-Arctic area inhabitable due to the abundance of nutrition from both fishes and sea mammals. Those species made life in the cold bearable.

    During the recent years, an understanding of the importance of the biodiversity in the Arctic has increased. Regulations, quotas and bans of fishing and hunting have been implemented in order to preserve the delicate Arctic environment.

  • Atlantic Ocean species Catch

    Species in the western Atlantic Ocean

    Five species fill up just over 50 percent of the fisheries in the northwest Atlantic Ocean.

    The Northern prawn is the biggest factor, counting for 17% of the total catch.

    The American sea scallop is the sexond biggest factor, 14% and the Atlantic herring is at 11%. The Atlantic menhaden is at 10%.

    The picture on the rights shows the number for 2008.

    In the northeast Atlantic Ocean, which stretches around Europe, the Atlantic herring is by far the biggest factor. It counts for almost 30% of the total catch.

    The blue whiting, is also popular, at 16% and the Atlantic cod is only at 9%.

    Catch by species in the northeast

    Herring is the biggest factor in the northeastern part. Along with blue whitting and the cod they count up for 50% of the total catch.

    Six other species fill up approximately 25% of the total catch, the Atlantic mackerel, European sprat, aithe (Pollock), Sandeels (Sandlances), Haddock and Capelin.

    Others are numerous but count for much less.

    The Atlantic herring is important both in the east and the west, but other species are not as connected between the two sides.

  • Value of fisheries

    Fish export value by countries

    Fishing is the most important economy in Greenland, and a huge factor in Iceland.

    Although the numbers might not be as big in value as in Canada and Russia for example, fishing in Greenland counts for a total of 94% of the countries economy. Shrimps are 63% of that number.

    Comparison between the numbers in tons can bee seen here.

    Iceland exports fish in large style, but aluminum is another big export value.

    Other Arctic countries are all around 1% of fisheries regarding export value.

    In USA the number is around half a percent, but closer to 1.5 in Russia.

    The picture on the right shows the importance of fishing in the Arctic, where Greenland and Iceland stand out.

  • Catch by Countries

    Fisheries in tons for the past 60 years.

    Here is a graph that shows how much six Arctic states caught. The numbers do not include whaling, but the numbers are in tons.

    The numbers date back from 1950, except for Russia.

    This shows the biggest fishing nations in the Arctic.

    It shows very well that USA is the biggest fishing nation, somewhat a surprise for many.

    Russia is also very big in numbers, especially in 1990.

    It is very interesting to compare this to the importance of fishing for the countries, and the export numbers. It shows that although both USA and Russia are hunting a lot, it is not very important for their economy.

  • Environmental study in Jan Mayen

    Environmental study in Jan Mayen

    Map of Jan Mayen and the Exclusive Economic Zones around the island and the EEZ´s of the neighbouring countries.

    Environmental study of proposed oil drilling near Jan Mayen will proceed in the near future, despite strong opposition of environmentalist, according to Reuters.
    Jan Mayen is a Norwegian archipelago north of Iceland. The Map shows the EEZ around Jan Mayen, which Norway is entitled to.

    Ola Borten Moe, Minister of Petroleum and Energy in Norway, confirmed that formal studies and reports will go ahead.

    “An impact assessment of Jan Mayen is … important,” Moe said in a statement. “It will cast light on important aspects of opening up for petroleum activities.”

    The length of the study is still unknown but if there are no major environmental or other hurdles, oil companies could be licensed to look for reserves across 100,000 sq km (38,600 square miles) of ocean.

    The last time a new area was opened to exploration in Norwegian territorial waters was 1994, the ministry said.

    Oil reserves are thought to be in the area, Iceland is also hoping to discover oil in the Dreki area, close to Jan Mayen. Iceland has invited for bids for oil search in the area, the bidding closes in February 2012.

  • Fishing Graphs

    Division of the Pacific and Atlantic oceans

    The eight Arctic states all catch fish. The species and quantity naturally varies between them.

    In this section comparison is shown between the states, where they are fishing, what and how much.

    Fishing is a part of every nations export value, but the difference is staggering. For example is fishing the backbone of the Greenlandic economy, counting for around 94% of their export value. Most countries rely on other means, where fishing is not very important.

    The map on the rights shows the Arctic. The Arctic Ocean is aligned with the Pacific Ocean and the Atlantic Ocean.

    The northwestern part of the Pacific is near Alaska but the northeastern part goes from Russia and all the way to Japan.

    The Atlantic Ocean northwestern part is around Canada and the USA, but also stretches up to Greenland.

    The Atlantic´ northeastern part stretches to Europe, to Portugal and up to Russia where the Arctic Ocean takes over.

  • Atlantic and Pacific Ocean Catch

    Atlantic ocean catch in total 2011

    The first graph shows the Atlantic Ocean. The blue colour is the northwest and the orange for northeast.

    To see the total number of tons cought gives a good overview of fishing in the Arctic.

    Here is a map that shows the oceans and how they are divided by east and west.

    The numbers are in tons and show comparison between decades. The first ones are from 1950 and the last ones from 2008.

    The colours show how much more is is caught in the northeast. One could say that the northeast is Europe and the northwest Canada and Greenland, but Greenland actually accounts for numbers both in the east and the west.

    In Europe countries like Spain, Portugal and England all catch alot of fish and make up the numbers with many other states

    Catch in the Pacific Ocean 2011

    The graph shows that there is not necessarily a connection between the east and the west in quantity of fish cought. There are of course many reasons for this.
    One can be the dependance on fisheries with the nations. The number of states is also a big factor, one set of numbers is only for a part of USA, Canada and Greenland, but the others for many countries in Europe.

    Since 1970, quantity has decreased in the northwest. This is for USA, Canada and Greenland and could mean that with increased tecnhnology, fisheries are not as important as before.

    One can also see that the difference between the numbers from 1950 and 2008 are very little, which shows the need for fish and his importance.

    The second graph shows the Pacific Ocean. The blue colour is the northwest and the orange colour is northeast.

    The difference between the east and the west is even greater in the Pacific Ocean, but vice-versa from the Atlantic where the eastern nation catch more.

    Again there appears to be little relation between the east and the west.

    But this shows that both the east and the west fish more today then in 1950.

    The numbers in the west grew significantly until 1990, but then started to fell.

    The difference in the east is not that much since 1970 to 2008.

  • Whaling in the Arctic

    Whaling in the Arctic

    Arctic Portal news

    It is assumed from the existence of Stone Age rock carvings of whales that Neolithic folk knew of them, though it is not clear if their knowledge was from animals washed up or stranded on beaches, or weather they hunted whales, using boats to drive them to shore for killing. That technique, still used in the Faroe Islands today, was certainly in use in the 9th century Norway.

    The construction of Whale Alley on Yttygran Island, which dates from a later, though still early, period, indicates that the ancestors of today’s Inuit were also hunting whales many centuries ago.

    By the 16th century Basque fisherman from Spain, who has hunted whales in the Bay of Biscay and were already fishing cod near Newfoundland, began to hunt whales in that area. From written accounts and archaeological evidence they hunted around 450 whales annually. The species were Northern Right Whale and the Bowhead whale.

    Harpoon is actually a Basque word and the Spaniard techniques were used by others because of their success. Around Bear Island and Svalbard many nations flocked to hunt whales, among them British and Dutch ships.

    Large ships transported men to the whaling area, from the ships the men used rowing boats to get to the whales. The men killed the whale and towed it to the shore where the blubber was rendered and poured into barrels. The barrels were then loaded back to the big ship.

    The shore station became larger and larger; a famous one on Spitsbergen in Svalbard can still be seen today, Dutch station Blubber Town. The infamous station is thought to have portrayed everything a town of 10.00 people needed, a bakery, a dance hall, a gambling hall and a brothel. The Archeological evidence suggest that this view is far from the truth, portraying a small town of 200 people at most, housed in barrack-like rooms, and an absence of clergy and women.

    The Danes, French and Germans all sent ships to Svalbard to hunt whales. With British and Dutch ships growing as well, the whale stocks soon depleted. By the 1640´s the catch barely covered the cost of the voyage and Blubber Town was abandoned. Whaling in Jan Mayen also soon depleted after British and Dutch hunted until the stock fell immensely.

    These meant greater distances had to be covered to hunt the whales. That resulted in more dangerous voyages and both ships and men were lost. In 1830 a total of 19 of 91 British ships were lost during whaling, 12 more were seriously damaged and 21 more failed to kill a single whale. Further loss of ships in the near future put an end to British whaling in the area.

    Bowheads were also found in the Pacific. Because of huge amount of whale killing the Bowheads in the Bergin Strait found in the 1850´s were left in peace. At the same time Americans were hunting Sperm Whales both in the Atlantic and the Pacific. They had problems as well as the British and the whaling was dangerous for the Americans as well. Their losses and the development of petroleum industry that offered cheap alternative to whale oil meant an end to American whaling.

    But better ships and a call for whale products for fashion meant that whaling did not stop at all. Americans put up a whaling station in Alaska, hunting Bowhead.

    The figure how many Bowheads were killed vary between sources, but the most likely number is 120.000 to 150.00 in the whales eastern range (The Atlantic and Hudson Bay), around 20.000 in the Sea of Okhotsk and also around 20.000 in the Bering Sea.

    The result was disastrous for the whale stocks. The Atlantic stock was counted in hundreds after whaling stopped but Pacific numbers were higher.

    Today it is estimated that the Atlantic Bowhead population is still no more than 500-6000 animals (perhaps 450 on the western side, no more then 100 in the east). In the Pacific the number of Bowhead whales is thought to be around 6000-8000.

    For the Northern Right whale the numbers are even worse, only around 400 animals are thought to live in the Atlantic and only around 100 in the Pacific. Stocks of the species are growing very slowly.

    Treatment of the whales was thought to be very cruel. Some were towed for days while still alive and harpooning did not always kill the animals immediately.

    For the whales in the waters of the Arctic fringe, the pursuit was equally relentless. The Sperm whale was the main target at first, Rorquals are another specie that was hunted after development in equipment, Steam boats and explosive harpoons, invented by Norwegian Sven Foyn, helped. Rorquals were mostly hunted in the southern waters but also in the Arctic fringe.

    In 1986 the International Whaling Commission halted whale hunting. Japan, Norway and Iceland have issued scientific permits as part of their research programmes and therefore still hunt whales.

    Recent discussions have centered on accusations that such permits have been issued merely as a way around the moratorium decision; these have been countered by claims that the catches are essential to obtain information necessary for rational management and other important research needs. All proposed permits have to be submitted for review by the Scientific Committee following Guidelines issued by the Commission but the ultimate responsibility for their issuance lies with the member nation, according to the IWC website.

    The Scientific Committee comprises around 200 scientists, some nominated by member governments and others invited especially by the Committee itself.

    Disputes arose but Iceland, Japan and Norway claim that stocks in their waters is sufficient for harvesting without endangering the populations. Opponents disagree and say that population numbers are disputed, and they whales should have the benefit of the doubt.

    The main species the three whaling nations hunt are Minke whale, Fin whale and Humpback whales.

    In Iceland in 2007, 39 common minke whales were caught under special permit in accordance with the original research proposal. A total of 200 common minke whales have been caught since the start of the research programme in 2003.

    Japan has issued scientific permits every year in recent years. In the current year, permits are for the JARPA II programme (850±10% Antarctic minke whales, 50 fin whales and 50 humpback whales) and the JARPN II programme (340 minke, 50 Bryde’s, 100 sei and 10 sperm whales) are allowed.

    Norway has not sent a scientific permit for a few years.

    The IWC set catch limits for stocks subject to aboriginal subsistence whaling.

    That means native people in Alaska (USA), Chukotka (Russia), Washington State (USA) and Greenlanders cam hunt whales, along with St Vincent and The Grenadines.

    Alaskans and the people in Chukotka can land 280 bowhead whales in 2008-2012 (67 each year at the most) and a total of 620 gray whales in the same time period (140 each year at the most).

    In St. Vincent and the Grenadines the number of humpback whales in the four year period is 20.

    Greenlanders can land in these four years 12 east common minke whales, 2 west bowhead whales, in the time period of 2010-2012 they can land 16 west Greenland fin whales, 178 west common minke whales and 9 west Greenland humpback whales.

  • UArctic funds slashed in Canada

    UArctic funds slashed in Canada

    Lubov Radnaeva, secretary of the UArctic council and Lars Kullerud, president of the UArctic.

    The Canadian government has slashed its funding to the University of the Arctic from 710.000 to 150.000. Subsequently Canada will lose the office it hosted at the University of Saskatchewan, which was staffed by UArctic’s dean of undergraduate studies, Hayley Hesseln.

    Since UArctic’s launch in 2001, Aboriginal Affairs and Northern Development had contributed more than $4 million a year to UArctic – money that went, among other things, to develop its undergraduate circumpolar studies program, now offered through Nunavut Arctic College.

    Hesseln said the flow of money stopped when territorial governments expressed interest in pursuing their own institutions, and the vision of what a northern university should be.

    “We’ve reached a point where the federal government is interested in funding the University of the Arctic, but the territories want to do their own thing,” she said according to Nunatsiaq Online.

    The result is that Canada will have little say in the UArctic network’s curriculum development, she said, while Canadian students will have a more difficult time accessing its programs, offered through 33 Canadian universities.

    Founded in 2001, the network now boasts 121 institutions, 33 of them Canadian. UArctic has had more than 10,000 registrations for its courses since 2002, said Hesseln.

    “You have a lot of aboriginal students in the North and they don’t do as well when they come to a large southern institution. They will be more successful taking these courses online in their own communities.”

  • Rock and roll satellite

    Rock and roll satellite

    ice saltellite

    ESA’s ice satellite is collecting data in the two poles, and the project is going well. The satellite is to give precise measurements of the vast ice sheets that blanket Greenland and Antarctica.

    Since its launch 18 months ago, CryoSat-2 has been collecting data to improve our understanding of the relationship between ice and climate, according to ESA website.

    For the first time a map of the Arctic sea-ice thickness was released, by ESA. The ice-satellite is to thank for that map and it is still colleting data.

    To ensure the precision of the measurements, an operation is under way to roll the satellite from side to side as it flies over the flat oceans. This maneuver is to calibrate CryoSat’s radar altimeter for measuring ice thickness, especially over the margins of ice sheets.

    The altimeter has two antennas mounted on a bench about a meter apart. When it is working in the ‘SARIn’ mode, both antennas are used in parallel: one emits a signal and both receive the signals that bounce back.  

    Normally, this bench is parallel to Earth’s surface. But at the edges of the ice sheets, the ice surface is not always flat and the slopes affect the return signals.

    Harsh conditions in space – with huge temperature differences between Sun and shade – can lead to the deterioration of CryoSat’s instruments, which can also lead to measurement errors.

    ice satellite

    In order to quantify these errors, ESA ground controllers are working to recalibrate the altimeter.

    They are rolling the satellite to simulate the ice slopes and holding it in this position for several minutes. This must be done while CryoSat is over large, flat surfaces. For satellite altimeters, oceans are Earth’s largest flat surfaces.

    It will also check whether errors are related to CryoSat’s varying thermal conditions – like when exposed to the Sun or in the shade.

    “With the results from the different sets of rolls over different ocean surfaces and at different ambient conditions, we are aiming to characterize the instrument to a precision better than we thought we could make at the time of the launch,” said Tommaso Parrinello, CryoSat mission manager.

    During several maneuvers on Monday and Tuesday, the satellite is rolling 0.4º to both sides while over the Indian and Pacific oceans, before returning to its original position.

    “The preparations for the roll activities have been quite challenging,” explained Nic Mardle, spacecraft operations manager.

    “Although we had experience of these activities from the commissioning phase, we had to iterate a few more times with the planning and mission control teams so that we could support exactly what was required.”

    Satellites have already shown that the extent of sea ice in the Arctic is diminishing. In fact, this year’s minimum has set a new record low.
