Study examined blood level changes in PCBs over a decade It's never been easy to be a polar bear. They may have to go months without eating. Their preferred food, seal, requires enormous luck and patience to catch. Add to that the melting of Arctic sea ice due to climate change, and the poisoning of the Arctic by toxic chemicals, and it's easy to see why polar bears worldwide are in trouble. Among all the bad news, however, comes one possible bright spot. In a study of PCBs in polar...

Image 1 - Ancient Whales Tell The Story Of Their Modern Relatives
2012-03-23 11:09:33

Smithsonian scientists have recently described a new species of toothed whale that once lived in warm climates during the Pliocene era 3-4 million years ago. These whales may have possibly been a close relative to the modern day Beluga and Narwhal. Those happy looking whales, the Beluga and Narwhal, live exclusively in colder climates like the Arctic and sub-arctic. The challenge now for the scientists is to uncover the mystery of why the whales moved farther north when once they were...

Increase In Arctic Shipping Poses Risk To Marine Mammals
2012-03-19 04:00:16

A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region's marine mammals and the local communities that rely on them for food security and cultural identity, according to an Alaska Native groups and the Wildlife Conservation Society who convened at a recent workshop. The workshop–which ran from March 12-14–examined the potential impacts to the region's wildlife and highlighted priorities for future...

Space For The Arctic
2012-03-15 08:09:43

[ Watch the Video ] International stakeholders met in Copenhagen this week to discuss the contribution of space technologies to one of the region´s most affected by climate change. Rendered increasingly accessible by the melting of ice, the Arctic is being transformed from a region of primarily scientific interest into one attracting a complex set of environmental, security and commercial concerns. Because of the Arctic´s harsh environment and low population density, space...

A new species adds to evidence that subarctic regions with vanishing waters contain unique aquatic animals Freshwater ecosystems in northern regions are home to significantly more species of water fleas than traditionally thought, adding to evidence that regions with vanishing waters contain unique animal life. The new information on water fleas -- which are actually tiny crustaceans -- comes from a multi-year, international study that was published Feb. 24 in the journal Zootaxa....

According to a new study, Arctic sea ice reductions may be intensifying the chemical release of bromine into the atmosphere, causing ground-level ozone depletion and the deposit of mercury in the Arctic. A team of scientists combined data from six NASA, European Space Agency and Canadian Space Agency satellites to develop a model of how air moves in the atmosphere to link Arctic sea ice changes to bromine explosions over the Beaufort Sea. "Shrinking summer sea ice has drawn much...

Thickest Parts Of Arctic Ice Cap Are Melting Faster
2012-03-01 04:33:50

[ Watch the Video ] A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean´s floating ice cap. The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed over winter just as quickly melts again. The rapid disappearance of older ice makes Arctic sea ice even more vulnerable to further decline in the summer,...

Diminishing Arctic Sea Ice Linked To Colder, Snowier Winters
2012-02-28 05:51:56

Melting Arctic sea ice will mean colder winters with more snow in the Northern Hemisphere, according to a new study published Monday in the Proceedings of the National Academy of Sciences. The research provides further evidence of a relationship between melting ice in the Arctic regions and extensive cold outbreaks across northern continents. The study could also help improve seasonal forecasting of snow and temperature anomalies throughout Europe, North America and China, the...

Even In Winter, Life Persists In Arctic Seas
2012-02-23 04:59:29

Results of research cruise to Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling Despite brutal cold and lingering darkness, life in the frigid waters off Alaska does not grind to a halt in the winter as scientists previously suspected. According to preliminary results from a National Science Foundation- (NSF) funded research cruise, microscopic creatures at the base of the Arctic food chain are not dormant as expected. After working...

Alaskan Hare, Lepus othus
2014-05-19 10:40:26

The Alaskan hare (Lepus othus), or the tundra hare, can be found on the Alaskan Peninsula and in western areas of Alaska. This species prefers to reside in rocky areas in their tundra habitat, resting in open areas rather than in burrows. It is most closely related to the mountain hare and the Arctic hare. Members of this species reach an average weight between 1.6 and 2.2 feet, with hind feet that reach a length of 7.9 inches. The hind feet are thought to help the hares move quickly and...

Arctic Ocean

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Continental arctic air mass is known for its very frigid and dry air. The most common place in the United States to find this air mass is in Alaska. However, in the coldest parts of the winter such as December and January along with early February it is not uncommon for this air mass to invade the Northern part of the United States. This air mass is responsible for bringing with it temps that drop well below zero. Along with the cold temps the air is very dry and if people stay outside in...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

The Common Redpoll (Carduelis flammea), is a species in the finch family. It breeds throughout northern North America and Eurasia. Subspecies of the Common Redpoll include the Arctic Redpoll and Mealy Redpoll. These are common too in the Arctic, Iceland, Greenland, and Baffin Island. They all migrate south into southern Canada, northern United States and most of Eurasia. These birds are remarkably resistant to cold temperatures and winter migration is mainly due to lack of food rather...
