    Arctic Christmas, Christianity and beliefs

    The Coke Santa-clausNow in the Arctic region, as elsewhere, the time of Christmas has started, except for in the Russian Arctic. In various regions in the Arctic, Christmas is a quite new idea which was introduced by western missionaries. The North has been a periphery for western civilization for numerous years and western Christmas traditions do not root so deep within Arctic communities.

    Everywhere along the Arctic, Christianity was brought upon, pronounced or forced to the residents in the Arctic region. As a result, vast majority of all Arctic residents are affiliated with some form of Christianity. Various Protestant churches dominate in northern Fennoscandia, Iceland, the Faroe Islands, Greenland, Alaska, and parts of northern Canada, while the Russian Orthodox Church is prevalent in the Arctic regions of the Russian Federation and in addition has limited presence in Alaska and parts of Finland.

    Finally, the Roman Catholic Church is particularly strong in parts of Canada and Alaska. There is considerable variation as to when Christianity reached different parts of the Arctic. While it happened almost 1,000 years ago in northernmost Europe, the inhabitants of the Chukchi Peninsula in the Russian Far East had little first-hand experience with Christianity before the 1990s. Generally speaking, the 18th and 19th centuries were the major periods of religious conversion in the Arctic. There have been various attempts to explain the rapid conversion of Arctic peoples to Christianity. Most authors agree that a combination of several factors is responsible. The adoption of Christianity rarely, if ever, resulted in the simple replacement of one religious system by another. Instead, old and new beliefs were reintegrated within a new system that was both Christian and local (Arctic Human Development Report).

    Even though Christianity was brought to the Arctic region, old pagan beliefs persist among Arctic residents. All northern indigenous peoples believe that there is a close relationship between humans and nature. Humans and animals are said to be able to understand each other. Animals were said to have spirits which affect the fortune of humans.

    Angry spirits caused illness and benign spirits helped the hunter by guiding animals into his path. Traditionally, the wishes of the spirits could be found out by a spirit medium called a shaman. In a special ritual performance, the shaman would go into a trance. It was thought that the shaman’s soul had left his or her body and flown to the land of the spirits. Here, the shaman would try to get back the soul of a sick person which had been captured by the spirits, or to get the spirits to promise that the hungry community would catch an animal (The Arctic Is). These believes are called shamanism and animism.

    However, Some of these beliefs have grown weaker during this century under the influence of Christian missionaries, teachers and government officials. For a long time, indigenous peoples themselves turned their backs of these beliefs in order to appear ‘modern’. But many ideas about the relationship between humans and animals remain strong. Some Inuit in Greenland still whisper ‘thank you’ to a seal they have just killed (The Arctic Is).

    Winter Solstice

    The complexity of modern Christmas celebrations should be seen in a historical perspective. In the early Christian Church, Easter, not Christmas, was the most important religious feast. Christmas celebrations only gained importance in the 4th century AD. The Roman Church adopted the date of December 25, celebrated by the Romans as the winter solstice. The choice expresses the close connection between Christ and the sun in early Christian religion. Christ rapidly adopted striking features of the sun god Helios such as the halo. In the Roman Empire the celebration of Christmas replaced the feast of Sol Invictus, the rebirth of the sun at December 25.

    The seasonal significance of the winter solstice is in the reversal of the gradually lengthening nights and shortening days. How cultures interpret this is varied, since it is sometimes said to astronomically mark either the beginning or middle of a hemisphere’s winter. Winter is a subjective term, so there is no scientifically established beginning or middle of winter but the winter solstice itself is clearly calculated to within a second. Though the winter solstice lasts an instant, the term is also colloquially used to refer to the full 24-hour period of the day on which it occurs. Worldwide, interpretation of the event has varied from culture to culture, but most cultures have held recognition of rebirth, involving holidays, festivals, gatherings, rituals or other celebrations around that time (Wikipedia).

    However, by a description of Franz Boas, the celebration of winter in an Inuit community in Qiqirtat (Kekerten Island, Canada), feast was not connected to the winter solstice, but prepared the hunting of the winter season. In the course of the ritual the success of the hunt is assessed in various divinatory games such as the tug-of-war of the ptarmigans and the ducks. Thus we may infer from the structure of the ritual that the relationship to the spirits of the dead is decisive in determining the success of the hunt. It is remarkable that the animals themselves never are partners in the ritual interactions between the Inuit with either the spirits of the dead or Sedna and her representatives, the qailertetang (Le Journal de la Société des Américanistes)

    BeiweThe Saami, indigenous people of Finland, Sweden and Norway, worship Beiwe, the sun-goddess of fertility and sanity. She travels through the sky in a structure made of reindeer bones with her daughter, Beiwe-Neia, to herald back the greenery on which the reindeer feed. On the winter solstice, her worshipers sacrifice white female animals, and with the meat, thread and sticks, bed into rings with ribbons. They also cover their doorposts with butter so Beiwe can eat it and begin her journey once again (Wikipedia).

    In Scandinavia and Iceland the arrival of Juletid (Christmas) came to refer to the midwinter celebrations. By the late Viking Age, the Yule celebrations came to specify a great solstitial Midwinter festival that amalgamated the traditions of various midwinter celebrations across Europe, like Mitwinternacht, Modrasnach, Midvinterblot, and the Teutonic solstice celebration, Feast of the Dead. A documented example of this is in 960, when King Håkon of Norway signed into law that Jul was to be celebrated on the night leading into December 25, to align it with the Christian celebrations. For some Norse sects, Yule logs were lit to honor Thor, the god of thunder. Feasting would continue until the log burned out, three or as many as twelve days. The indigenous lore of the Icelandic Jól continued beyond the Middle Ages, but was condemned when the Reformation arrived.

    The celebration continues today throughout Northern Europe and elsewhere in name and traditions, for Christians as representative of the nativity of Jesus on the night of December 24th, and for others as a cultural winter celebration on the 24th or for some, the date of the solstice (Wikipedia).

    Modern Christmas Celebration

    Even though the traditional Christian belief of Christmas is predominant, many local customs and traditions live along the culture among the Arctic and they root to their old pagan roots. In Scandinavia the equaliant for Santa Claus is the Tomte or Nisse. It is a mythical creature of Scandinavian folklore originating from Norse paganism. Tomte or Nisse were believed to take care of a farmer’s home and children and protect them from misfortune, in particular at night, when the housefolk were asleep. Tomte is a common Swedish name, derived from his place of residence and area of influence: the house lot or tomt. The Finnish name is tonttu. Nisse is the common name in Norwegian and Danish.

    HurdaskellirThe Yule Lads, Yulemen, or Jólasveinarnir are figures from Icelandic folklore who in modern times have become the Icelandic vector of Santa Claus and are in total of 13. The Yule Lads were originally portrayed as being mischievous, or even criminal, pranksters that would steal from, or in other way harass the population (at the time mostly rural farmers).

    They all had descriptive names that conveyed their mode of operation. The Yule Lads are traditionally said to be the sons of the mountain-dwelling trolls Grýla and Leppalúði. Additionally, the Yule Lads are often depicted with the Yuletide Cat, a beast that, according to folklore, eats children that don’t receive new clothes in time for Christmas.

    In the culture of the eastern Slavs the traditional character Ded Moroz plays a role similar to that of Santa Claus. The literal translation of the name would be Grandfather Frost. Ded Moroz brings presents to children. However, unlike the secretive ways of Santa Claus, he often brings them in person, at the celebrations of the New Year, at New Year parties for kids by the New Year Tree.

    The “in-person” gifts only occur at big organized celebrations, where the gifts can be “standardized.” The clandestine operations of placing the gifts under the New Year tree still occur while the children are young. Ded Moroz is accompanied by Snegurochka or ‘Snow Maiden’ , his granddaughter. The traditional appearance of Ded Moroz has a close resemblance to that of Santa Claus, with his coat, boots and long white beard. Specifically, Ded Moroz wears a heel-long fur coat, a semi-round fur hat, and white valenki or high boots (sapogi), silver or red with silver ornament. Unlike Santa Claus, he walks with a long magical staff, and drives no reindeer but a troika (Wikipedia).

    Santa on the NorthpoleNowadays, The traditional western Santa Claus is considered to be an Arctic resident. While his exact location is not known, there are some strong beliefs that his whereabouts are at the North Pole where he has his toy factory. However scientists have not yet discovered the Santa Clause home even though that various observations have been taken place in the Arctic, close to the North Pole and on the Pole itself. Dispite that fact, Santa Claus still appears every year and brings joy to thousands of peoples all across the world.

    Due to that fact alone, people should be aware of the changing climate and global warming, for the Santa´s workshop might be at risk.

  • Treaty for the Arctic?

    Treaty for the Arctic?

    The sea divided into east and west.

    Diplomats and fisheries officials from five Arctic states will meet in Washington later this month to discuss regulations on commercial fishing near the North Pole.

    Government representatives from five Arctic states, i.e. Norway, Denmark, Canada, United States and Russia, agreed yesterday to meet later this month in order to discuss the laws that will apply to commercial fishing within the Arctic Circle.

    About 70 percent of the world’s total white fish supply comes from Arctic waters. This marine resource is extremely significant to Arctic regional and coastal communities.

    Fishing in the Circumpolar North has been and is a significant economic resource. Fishing is also rooted in the culture of many of the Arctic nations.

    World catch in numbers

    Now Exclusive Economic Zones divide where nations can catch fish but this economic activity has shaped the cultural values in the Arctic and is an important factor in the daily life of the coastal residents.

    If an agreement is made, it will represent the third such accord struck by countries in the far north to manage the commercial development and industrialization of the region, which is expected to increase with global warming. The other two agreements reached so far regulate oil spill response and search and rescue.

    The 12th Conference on Polar Meteorology and Oceanography that will take place in Seattle, Washington on 29th of April, is sponsored by the American Meteorological Society and organized by the AMS Polar Meteorology and Oceanography Committee.

    This year it will treat not only about natural science but also serve as a place to discuss legal and political issues between Arctic stakeholders.

  • Cold winter conditions in the Arctic

    Cold winter conditions in the Arctic

    Climate conditions have been negative

    States for 2012 was climate conditions in Scandinavia, Siberia, Alaska and Canada have been colder than average this winter.

    The National Snow and Ice Data Center reports that the Arctic sea ice extent for December 2012 was well below average, driven by anomalously low ice conditions in the Kara, Barents, and Labrador seas.

    NSIDC states that the winter has been dominated by the negative phase of the Arctic Oscillation, bringing the cold climate around the Arctic.

    The Arctic Oscillation is an Arctic climate index with positive and negative phases, which represents the state of atmospheric circulation over the Arctic. The positive phase brings lower-than-normal pressure over the polar region, steering ocean storms northward, bringing wetter weather to Scotland and Scandinavia, and drier conditions to areas such as Spain and the Middle East.

    Reports today also show that the average temperature for USA for 2012 was above average, showing different climate than in the Arctic, outside of Alaska.

  • Arctic brings cold weather to China

    Arctic brings cold weather to China

    A man works in a frozen river in Taiyuan, Shanxi province

    The year 2012 was unusually cold in China, which may be a result of the record loss of Arctic sea ice. “Observation and data analysis showed that Arctic sea ice loss may cause cold and snowy winters in parts of Asia,” Chen Yu, senior engineer of the National Climate Center in China states.

    The Arctic sea ice saw it record low extent on September 16th 2012.

    The China Daily reports and Chen explains that when sea ice melts in the Arctic, the water temperature increases. When that happens, the air becomes moister and is more likely to form cold fronts.

    According to the China Meteorological Administration, in December most of China suffered colder weather than usual. On Dec 24, frequent cold fronts led to temperatures in 21 monitoring stations hitting record lows.

    And the cold weather continued and the weather has been cold since late December.

    Kang Zhiming, weather forecaster of the National Meteorological Center, said weather models showed the temperature will not rise until late January.

    “The weather authorities will keep a close eye on any changes in the weather, especially before Spring Festival, in order to give timely information to transport and related departments, particularly in the event of extreme weather,” Kang said.

    China has a research station in Ny Alesund, on Svalbard, and among other projects is monitoring weather and sea ice from the station.

  • Transpolar flights, a shortcut through the Arctic

    Transpolar flights, a shortcut through the Arctic

    Arctic Voyage of Richard Byrd and Umberto Nobile

    “Aviation is a proof that given, the will, we have the capacity to achieve the impossible.”

    Eddie Rickenbacker

    Long before the jet age, commercial aircraft were flying through the Arctic Circle. After the successful voyages of Richard Byrd and Umberto Nobile in 1926, the feasibility of polar aviation was demonstrated in actual practice. Nowadays, commercial traffic, connecting Europe, North America and Asia through the north polar routes is a routine.

    Cross-polar air corridors bring new opportunities for both commercial and private travel markets. Transpolar aviation reduces the burn of fuel by making the travel time shorter what lowers the cost of trans-polar air operations.

    Flying direct paths between many of North American and Asian cities also decreases the environmental threats of greenhouse gases emissions, which are now one of the major concerns of the Arctic States.

    Polar air corridors refer to aircraft routes lying across the uninhabited polar ice cap region, 78 degrees north from the northern latitude what includes areas of northern part of Alaska and most of Siberia. Term of Polar Route was originally adopted in the middle of 20th century and applied to the great circle between Europe and west coast of North America.

    The Polar Route formally opened after the Cold War for commercial flights between Europe and Asian Far East as before that period civilian flights were not able to cross the air space over the Soviet Union and China as those countries were much concerned about the possibility of trans-polar attack.

    Nowadays commercial traffic through the northern hemisphere is operated by various aircraft as Boeing 747 – 400 and Airbus A340, with ranges of around 7000 nautical miles. In 2001, Arctic States adopted policy letter, Guidance for Polar Operations, which outlined a number of specific requirements for polar flight operations, including cold weather conditions, special communication capabilities, fuel freeze strategy, evacuation and recovery plans for abandoned passengers and special monitoring requirements as the aircraft operating in the Arctic rely almost exclusively on satellite communications, where a pilot´s signal is beamed into the space and bounced back to a ground control station.

    Modern aircraft flying the polar route

    Arctic operating planes handle the distances between Europe, Asia and North America and are managed by various airlines. The International Air Transportation Association proposed the establishment of the Pacific Project which would meet the increasing air traffic demand between Asia and North America which is very likely to double by the end of 2025.

    Opening of new and improving strategies on already used air traffic routes offer possibilities to reach various locations in the northern hemisphere in easy and cost efficient way.

    Trans-Arctic shipping routes appear to emerge as the fastest way of transportation between North America and Asia. Flying direct paths across the uninhabited Arctic ice cap region, helps aircraft to reduce the fuel burns, travel time and associated environmental carbon emissions.

    Advanced transportation technology increases the importance of airships for trade and economic development. It is being defined that aircraft able to fly the Polar Routes are the most competitive in northern areas without highly developed infrastructure.

    There are 676 airports currently maintained around the Arctic and majority of them is situated in Alaska, United States. There are 79 airports in Arctic Canada, 71 in Russia, 62 in Denmark (Greenland and Faroe Islands), 56 in Norwegian Arctic including Svalbard, 55 in Finland, 35 in Sweden and close to 20 in Iceland. Not all of them exist as ports of entries for international traffic as those are partly used domestically.

    (Map: Arctic Portal) Air shipping routes Interactive map aims to locate and provide with significant information with regards to Arctic airports. This research will show the mechanisms associated with Arctic air traffic in rather difficult, unique climate and familiarize with Arctic airports locations and information with regards to runway length and elevation to indicate approximate size of the airport and load classification.

    Trans – Arctic aviation leaves a significant scare in the fragile Arctic environment. All forms of air traffic used to cross the Arctic air space emit carbon dioxide and other greenhouse gases, like oxides of nitrogen and water vapor, into the northern atmosphere.

    Emissions of an Arctic airship can vary significantly, according to the size of the aircraft, the number of passengers on board, the distance of journey and the altitude as it was proved that aircraft flying on high altitudes produce more carbon dioxide than those operating on lower altitudes.

    Reducing air travels and Arctic air tourism opportunities seem to be another alternative way to reduce aviation impact on climate change and Arctic environment. If future travel demand could be managed with supplementary ways of transportation, increased taxation would not be needed to be implemented by the Arctic States.

  • New report on melting glaciers

    New report on melting glaciers

    Melting glacier in Svalbard

    A new report of current rates of changes of land ice in the Arctic and North-Atlantic region has been released. It shows that the Greenlandic glacier shrinks by 200 square kilometers every year.

    Helgi Björnsson, a glaciologist at the University of Iceland, says that the Greenlandic glacier is melting rapidly, at twice the rate in the last 10-20 years. The glacier tongue is also stretching further out in the ocean than ever.

    The report states that the world oceans are rising of 3,3 mm every year, and almost 1/5 of that is because of the Greenlandic glacier. Only 20 years ago it was 2 mm less per year.
    The report included research on ice in Greenland, Iceland, Svalbard and Scandinavia.

    Glaciers in Iceland are also getting thinner, by 1 meter every year. Since 1990 glaciers in Iceland has shrunk by 150 square kilometers.

    The report is available here, in the Arctic Portal Library.

    This is the first Interim report of current rates of changes of land ice in the Arctic and North-Atlantic region from the Nordic Centre of Excellence ‘Stability and Variations of Arctic.

    Land Ice’ (SVALI). SVALI is one of three Nordic Centres of Excellence within the Nordic Top Research Initiative sub-programme ‘Interaction between Climate Change and the Cryosphere’. The report (Deliverable D.1.1-7 in the project) is written by the partners in Theme 1 “Observing the present – baseline and changes”.

    The report is a step towards answering one of the key questions to be addressed within SVALI: How fast is land-ice volume in the Arctic and North-Atlantic area changing?

  • Arctic oil: setting risks too high?

    Arctic oil: setting risks too high?

    “A liquid substance that is greasy to the touch and formed by the breakdown of fats in fossil organic material: Oil.”

    (Map: Arctic Portal) Potential oil and gas fields in the Arctic

    This broad definition for oil is valid from everything between crude oil, the black flammable liquid sought by drilling, to the yellow vegetable oil used in cooking.

    Hydrocarbons – as they are often called – are in the broadest sense organic compounds of hydrogen and carbon. These exist in Earth’s subsurface in either liquid form – which is called (crude) oil or petroleum, or they exist in gaseous form, and then called natural gas.

    This week’s feature will answer the question of what is actual definition of Arctic oil and where it can be found. It will try to make you familiar with the long history of the Arctic oil as well as its formation and extraction. It will conclude with few words on environmental protection and prospects of future development.

    Oil rig at sea

    The “tool” to find deposits of oil or gas is the scientific branch of petroleum geology. Petroleum has a reputation as “Mother of all Commodities” as a number of materials are produced on a petroleum base – such as petrol, kerosene, plastics, medicines, basically all forms of organic chemicals. It is the most traded good amongst humans on this planet, followed by coffee and then natural gas. It is also the leading energy source of mankind: The combustion of fossil fuels—coal, oil, and natural gas—provides by far the largest portion of the current supply of energy.

    Within the Arctic, oil is today mainly found in three regions: The Beaufort Sea coast (North Slope of Alaska and the Mackenzie Delta of Canada), the Canadian north-eastern Arctic (Nunavut), and northwest Russia.

    In 2008, the US Geological Survey published an estimate of the undiscovered deposits in the Arctic. The impressive result was, that the area north of the Arctic Circle is expected to hold an estimated 90 billion barrels of undiscovered, technically recoverable oil, 1,670 trillion cubic feet of technically recoverable natural gas, and 44 billion barrels of technically recoverable natural gas liquids in 25 geologically defined areas thought to have potential for petroleum.

    These resources account for about 22 percent of the undiscovered, technically recoverable resources in the world. The Arctic accounts for about 13 percent of the undiscovered oil, 30 percent of the undiscovered natural gas, and 20 percent of the undiscovered natural gas liquids in the world. About 84 percent of the estimated resources are expected to occur offshore.

    Current oil and gas production areas

    Since fossil fuels are not renewable source of energy, their price and costs of production increase in line with increased consumption and diminishing known reserves. This leads to pressure to explore oil from territories earlier regarded as inhospitable.

    The Arctic and its resources are thus coming into focus: Depending on oil prices and the supply of oil from existing producing regions, such as the North Sea and the Middle East, there will likely be an increasing pressure to develop the Arctic reserves. There can already be seen strong indications that Arctic becomes one of the main sources of oil and gas in the twenty-first century.

    Historically there are three main regions in the Arctic linked to oil exploitation: the Beaufort Sea coast (North Slope of Alaska and the Mackenzie Delta of Canada), the Canadian north-eastern Arctic (Nunavut), and northwest Russia (Barents Sea and West-Siberia).

    Within the three, first developments of oil and gas fields took place in Russia (Komi Republic), then in Canada (Alberta) and finally in the USA (Alaska).

    Comparison of the development of oil and gas fields in the circumpolar North reveals two fundamental models of developing these resources: the European (or North Sea) model and the American (USA, and partially Canada) model. Both of which occur with regional peculiarities.

    The European model is often described as an “interventionist” or “state capitalist” system. Often a state-run national oil company plays the central role in developing and managing the resource. Private companies also participate directly, often in cooperation with these national oil companies. In addition the state has strong influence on the administration, issuing and allocation of production licenses including a strong influence on the requirements expected from private companies engaging in this model.

    Oil lies several layers down the earth

    In the so-called American model the state mostly has a regulatory role. Control over production and development is left in a relatively exclusive degree to private companies who obtain and compete for licenses and concessions through auctions.

    A major force of development throughout the circumpolar North came during the 1960’s and 1970’s due to political instabilities of major suppliers from the Middle East region. This made development of oil fields in Arctic and subarctic regions economically feasible and politically advisable. The development led to a number of new oil and gas fields both onshore and offshore as well as to the construction of according transport systems (pipelines).

    For example the Trans-Alaska Pipeline in Alaska was built between 1974 and 1977 and in Northwestern Siberia for a total of 14 years, from 1973 to 1986, at least one major construction project was undertaken either for major oil or gas pipelines each year. Often these megaprojects led to controversies with local population, as either resources were on traditional grounds belonging to indigenous peoples or the installation of oil fields or pipelines affected the traditional ways of subsistence (e.g. reindeer husbandry, fishing, hunting).

    There are numerous examples of megaprojects with a varying degree of involvement and participation of local / indigenous people in benefits and profits. Read more in the Megaprojects chapter of the Energy Portlet.

    Oil or hydrocarbon as it is often called – is in the broadest sense organic compounds of hydrogen and carbon. These exist in earth’s subsurface in either liquid form – which is called (crude) oil or petroleum.

    Petroleum and natural gas are formed from ancient biomass, thus the name “fossil” fuels for fuels based on petroleum or natural gas.

    Heating of prehistoric organic material leads to the formation of crude oil and natural gas. This happens over a long time via a set of complex biochemical and geological processes of pressure and seclusion from air (anaerobic conditions). The organic material usually mixed with mud clay, got buried under strong layers of sediment, thus generating conditions of high pressure and heat.

    This caused organic matter first to develop to a substance called kerogen and then with even more heat applied over geological time, becoming liquid or gaseous hydrocarbons.

    The subsurface reservoirs possibly blend with water and accumulate in chambers beneath the surface: The hydrocarbon compounds produced in this way were probably concentrated by being dissolved in water and transported through sedimentary rocks; the deposits were then trapped in dome-shaped chambers. However, petroleum can also remain oil shale or oil sands – such as in the Athabasca region of Canada.

    Oil barrels Prehistoric zooplankton and algae, plants and animals, from sea or lake bottoms, preserved under anoxic conditions, are the basis of today’s crude oil and natural gas. Prehistoric terrestrial plants are mostly the basis for today’s coal.

    Petroleum extraction is the whole process by which hydrocarbons (petroleum) is extracted and removed from the earth. The process is divided in three different stages: location, drilling and the actual oil extraction and recovery.

    Location of oil is defined by seismic surveys and gravimeters or magnetometers. An oil well is created by drilling into the earth with an oil rig. Offshore an oil rig is the platform from which the well is drilled. The actual hole is filled with a pipe made of steel. The idea is to fortify the integrity of the drilled hole. The bottom of the hole is finally perforated to allow oil to pass into the wellbore. On top of the well a structure with multiple valves is placed, called ironically „christmas tree”.

    The actually oil extraction and recovery after locating and drilling is subdivided into three stages.

    Several effects on the environment are linked to the different stages of oil extraction. Terrestrial, avian and marine fauna, flora and humans are all potentially affected when oil is sought. However, the oil spills still seem to be the biggest threat to fragile Arctic environment. Click here, to see the biggest oil spills that occurred close to the Arctic Circle.

    The Arctic is expected to host around 22% of the world’s remaining undiscovered oil and gas reserves, according to a 2008 assessment from the US Geological Survey. According to this assessment this would equal an estimated total oil and natural gas resource of 412 billion barrels of oil equivalent.

    Oil drilling platformAccording to the Energy Information Administration of the USA, the world total consumption of oil barrels per day in the year 2008 was 85.462, the yearly total being thus 31.193.630 billion barrels. This means that the whole world would be around 13 years to use all of the oil in the Arctic, should the whole 412 billion barrels be extracted and produced.

    Around 78% of the Arctic resources are expected to be natural gas and natural gas liquids (NGL). The West Siberian Basin and East Barents Basin are estimated to be key areas, holding 47% of the total undiscovered resources. 94 percent of the resources within these areas are expected to be natural gas and NGL.

    The North American part of the Arctic is expected to hold mostly oil whereas the Eurasian part of the Arctic seems to promise largely extended gas reserves: About 65% of the undiscovered Arctic oil are expected in the American part of the Arctic, compared to only 26% of the undiscovered Arctic natural gas.

    The major share of undiscovered oil deposits is expected to be in Arctic Alaska: About 30 billion barrels. Second is the Amerasia Basin, just north of Canada, with an estimate of about 9.7 billion barrels of undiscovered oil and third the East Greenland Rift, which is estimated to hold about 8.9 billion barrels of undiscovered oil.

    Altogether, these three North American provinces count for an expected sum of about 48.6 billion barrels of undiscovered oil, corresponding to around 54% of the total undiscovered oil in the Arctic.

    In the Barents Sea recent findings indicate that the Skrugard field contains an estimated amount of 250 million barrel oil reserves. Another field, Goliat is currently under development with an estimated reservoir size of 240 million barrels. It is also expected oil reserves are laying around Greenland; however exploration and test drilling have not yet led to any findings.

    Despite expected large reserves, the future of Arctic oil development is depending on technical, political and environmental challenges. Technical challenges are in general the harsh Arctic conditions that put special demands on men and material. Transport systems such as pipelines need to be constructed and in addition face technical challenges as climate change puts new requirements towards materials and construction technologies.

    the Arctic landscapePossible sovereignty disputes over land and sea areas in the circumpolar North could also delay the development of future oil fields. Regional examples such as from the Barents Sea, show how a long-lasting delimitation dispute can hold development for many decades. It was not until the 7th of July 2011, the day the Norwegian-Russian delimitation treaty in the Barents Sea entered into force that the Norwegian side started immediate prospecting for oil and gas.

    Last but not least there is the challenge of the vulnerable Arctic environment and the indigenous people of the circumpolar North that puts high demands to any oil or gas related project in the region. Increased transport, e.g. by tankers will also require new capabilities to Search and Rescue capabilities as well as oil spill prevention. High costs due to high environmental protection demands could delay or even halt a further development of Arctic oil, especially when cost / benefit calculations compare it with other regions.

    An increasing oil price could make the exploitation of oil shale and oil sand reserves e.g. in subarctic regions more reasonable and feasible than an immediate offshore drilling in the Arctic Ocean or adjacent shelves. Still a growing global demand for energy and challenges with energy security e.g. in the Middle-East region can give additional momentum to develop Arctic oil despite the named challenges.

    So despite an anticipated abundance of resources and a high demand, there are still high costs, high risks and lengthy lead-times to be expected that could potentially delay or even stall any further development of oil fields in the Arctic.

    One has thus to be careful in predicting if and when a significant increase in Arctic oil production is to be expected in the future.

    Oil pollution in the sea

    The chief executive of the energy company Total warns against oil drilling in the Arctic. He says that oil spills would destroy the image of companies.

    Total has had many oil projects in the Arctic, and still has several exploration projects concerning gas, which the executive, Christophe de Margerie, says is easier to deal with than oil spills.

    “Oil on Greenland would be a disaster,” de Margerie told the Financial Times. “A leak would do too much damage to the image of the company”.

    Financial Times states that this is the first time an oil major has publicly spoken out against offshore oil exploration in the region.

    Although not mentioning the fragile nature and environment in the Arctic, rather highlighting the image of the company concerning damage in oil spills, environmentalists are happy with the comments.

    de Margerie emphasized that he was not opposed to Arctic exploration in principle.

    The Financial Times also reports that Royal Dutch Shell had to postpone until next year an attempt to drill into oil-bearing rock off the Alaskan coast after a piece of safety equipment was damaged during testing. It has spent $4.5bn and seven years preparing to drill.

    Many companies are exploring and drilling for oil in the Arctic, ExxonMobil, ENI of Italy and Statoil of Norway amongst them, as well as Russian Giants Gazprom.

    Total’s Arctic projects are concentrated in Russia. As well as its stake in Shtokman, it has interests in a number of onshore developments, such as a big liquefied natural gas venture in Russia’s far north known as Yamal LNG. It also operates a Siberian oilfield called Kharyaga.

    According to a 2008 study by the US Geological Survey, the Arctic contains just over a fifth of the world’s undiscovered, recoverable oil and gas resources.
