Polarstern Has News About Arctic Sea Ice
2012-10-11 18:43:41

Alan McStravick for redOrbit.com — Your Universe Online The Polarstern expedition has disconcerting news about our rapidly receding sea ice. The Polarstern, an ice-breaking research vessel, returned to the port of Bremerhaven two days ago. The Polarstern, operating on behalf of the Alfred Wegener Institute, was conducting research into the retreat of sea ice and the impact it will have on the Arctic Ocean and its ecosystems over the last two months. In all, 54 researchers and...

Composition Of Microbial Populations Determined By Freshwater Flows Into The Arctic And Southern Oceans
2012-10-11 08:05:22

Part of NSF's International Polar Year research portfolio, the six-nation study indicates that shallow-water populations have little in common Differing contributions of freshwater from glaciers and streams to the Arctic and Southern oceans appear to be responsible for the fact that the majority of microbial communities that thrive near the surface at the Poles share few common members, according to an international team of researchers, some of whom were supported by the National Science...

The Arctic is getting warmer and wetter. As temperatures rise and sea ice melts, scientists suspect that system feedback cycles may further speed up the warming process. Now, a new study out of the University of Colorado at Boulder is showing how shifting patterns of humidity may bring about changes in the Arctic atmosphere. The new study compiled data from the 1950s through the present to examine the subtle changes in the Arctic atmosphere over time. The team then incorporated the data...

BELLEVUE, Wash., Oct. 2, 2012 /PRNewswire/ -- Eddie Bauer is proud to announce the completion of Team Arctic Row's non-stop, unsupported row across the Arctic Ocean. After spending 41 days rowing more than 1,000 miles through frigid Arctic waters, the team successfully finished their expedition in Point Hope, AK at 1:46 p.m. local time on Sunday, August 26, 2012. As a result, the team pioneered a new route for modern ocean rowing, which is considered to be the longest in Arctic history...

Polar Bear Researcher Cleared Of Scientific Misconduct
2012-09-30 07:50:11

redOrbit Staff & Wire Reports - Your Universe Online The scientist who helped bring the plight of the polar bear to the public's attention and helped get the creatures listed as a threatened species has been reprimanded by federal investigators for sharing internal government emails without authorization, but was cleared of scientific misconduct, according to reports. The results of the Office of the Inspector General for the Interior Department investigation into the conduct of...

Expedition to the Greenland Sea with Surprising Results Marine scientists from Kiel, together with colleagues from Bremen, Great Britain, Switzerland and Norway, spent four and a half weeks examining methane emanation from the sea bed off the coast of Spitsbergen with the German research vessel MARIA S. MERIAN. There they gained a very differentiated picture: Several of the gas outlets have been active for hundreds of years. Frequent storms and sub-zero temperatures — nature drove...

Arctic Ice Reaches Least Extent Since 2007 Summer Season
2012-09-20 09:23:03

Lawrence LeBlond for redOrbit.com - Your Universe Online The Arctic sea ice has stopped receding this year, but not before reaching its smallest extent, breaking the previous record set in the summer of 2007, by 18 percent. The new low sets the summertime ice area extent to about 2.1 million square miles, according to estimates from the US National Snow and Ice Data Center (NSIDC) in Colorado. This year´s unprecedented ice melt in the Arctic is the clearest sign yet of global...

Climate Change Shrinking Sea Ice, Seal Species Threatened
2012-09-17 15:49:26

Lee Rannals for redOrbit.com — Your Universe Online Scientists reported in the journal Geophysical Research Letters that the ringed seal is being threatened by shrinking sea ice in the Arctic. The ringed seal uses ice to build caves for its young, which need at least 8-inches of snow drifts on sea ice in order to be supported. Without sea ice, the platform that allows the snow to pile up disappears, reducing the area where seals can raise their pups. The researchers were...

Arctic Crustaceans Survive Ice Melt By Migrating Via Deep Ocean Currents
2012-09-14 11:29:59

Brett Smith for redOrbit.com - Your Universe Online As climate change tightens its grip on the polar regions, many biologists are investigating how different species that live there are being affected by increasing temperatures and decreasing polar ice. Some arctic crustaceans are showing why they have persisted for millions of years by adapting to the changes in their environment, according to a new report published in the journal Biology Letters by an international team of scientists....

John Neumann for redOrbit.com — Your Universe Online Sometime between 200 and 500 years ago, in the throes of a mini ice age, sea ice had become thick and stable enough for animal migration to occur between regions in far northern Europe. This sheet of ice gave arctic foxes a migration route to Iceland from previously unavailable landmasses, including present-day Russia, North America and Greenland. Scientists at Durham University reported findings highlighting the importance of...

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...

The Arctic fox (Alopex lagopus), also known as the polar fox, is a small fox native to cold Arctic regions of the Northern Hemisphere. It is common in all three tundra biomes. Although some authorities have suggested placing it in the genus Vulpes, it has long been considered the sole member of the genus Alopex. The Arctic fox has smaller, more rounded ears, a more rounded braincase. It has a slightly shorter and broader muzzle than the red fox. Its feet are furrier than those of other...
