Provided by Dr. Tony Phillips Science@NASA Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place in particular - the Arctic. "Polar regions are important for us to study right now," explains Tom Wagner of NASA's Earth Science Division in Washington DC. "They are changing rapidly." One of the most visible of signs of warming is the retreat of Arctic sea ice. Every year, sea ice waxes and wanes in a normal response to the changing of seasons;...

Fish Moving Into Arctic And Antarctic Waters At Rate Of 26 Kilometres Per Decade
2014-10-13 03:18:50

Provided by Heather Amos, University of British Columbia Large numbers of fish will disappear from the tropics by 2050, finds a new University of British Columbia study that examined the impact of climate change on fish stocks. The study identified ocean hotspots for local fish extinction but also found that changing temperatures will drive more fish into the Arctic and Antarctic waters. Using the same climate change scenarios as the Intergovernmental Panel on Climate Change,...

Flights Rerouted Due To 35,000 Walruses Massed On Alaskan Beach
2014-10-03 07:47:41

Eric Hopton for redOrbit.com – Your Universe Online A dense mass of Pacific walruses, estimated to be 35,000 strong, has gathered on a beach in northwest Alaska, approximately five miles north of Point Lay. Scientists believe this unprecedented number of animals has been driven to shore by a lack of sea ice. The UK’s Guardian newspaper reported today that the United States Federal Aviation Authority (FAA) has rerouted flights in the area in order to reduce the risk of planes causing a...

WASHINGTON, Sept. 16, 2014 /PRNewswire-USNewswire/ -- Over the past few decades, average global temperatures have been on the rise, and this warming is happening two to three times faster in the Arctic. As the region's summer comes to a close, NASA is hard at work studying how rising temperatures are affecting the Arctic. http://photos.prnewswire.com/prnvar/20081007/38461LOGO NASA researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed...

WASHINGTON, Sept. 3, 2014 /PRNewswire-USNewswire/ -- The year 2015 is going to be a pivotal year in the development of the Arctic; the US is going to assume chairmanship of the Arctic Council and EU is going to make a determined effort to be admitted as an official observer to the Arctic Council. The Center for Regulatory Effectiveness (CRE) , who provides staff support to the Pan Arctic Forum, believes that the development of the Arctic resources should be science based and that the...

Chuck Bednar for redOrbit.com - Your Universe Online The Paleo-Eskimo people that lived in the Arctic from roughly 5,000 years ago to about 700 years ago, were the first humans to live in the region and survived there without outside contact for more than 4,000 years, researchers reported Friday in the journal Science. In addition, lead investigator Eske Willerslev of the Centre for GeoGenetics at the Natural History Museum of Denmark and her colleagues report that the Paleo-Eskimos...

Patrick Lynch, NASA’s Earth Science News Team As we near the final month of summer in the Northern Hemisphere, NASA scientists are watching the annual seasonal melting of the Arctic sea ice cover. The floating, frozen cap that stretches across the Arctic Ocean shrinks throughout summer until beginning to regrow, typically around mid-September. As of Aug. 19, Arctic sea ice covered about 2.31 million square miles. While this is on track to be larger than the record-breaking low year in...

Snow on top of sea ice
2014-08-14 03:30:55

George Hale, NASA's Goddard Space Flight Center Over the past few decades, Arctic sea ice has been retreating, and although research shows a downward trend in snow on land in the Arctic, long-term measurements of snow depth on sea ice have been less clear. But now, new research using data from NASA's Operation IceBridge shows that snow depth on Arctic sea ice has been decreasing over the past several decades, a trend largely owing to later sea ice freeze-up dates in the Arctic. Arctic...

Finding Deepest Iceberg Scours To Date Provides New Insights Into Arctic’s Glacial Past
2014-08-13 03:02:09

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. The five lineaments, at a depth of 1,200 meters, are the lowest-lying iceberg scours yet to be found on the Arctic sea floor. This finding provides new understanding of the dynamics of the Ice Age and the extent of...

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...
