Arctic Sea Ice Trends
2014-03-05 08:10:23

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

Reindeer Counteract Effects Of Climate Warming
2014-02-18 16:09:12

Umeå University One of the consequences of a warmer climate can be that lowland and southern plants migrate higher up in the mountains. Ecologist Elina Kaarlejärvi shows in her thesis that reindeer, voles and hare can prevent these invasions. The public defense will take place at Umeå University, 21st of February. Elina Kaarljeärvi concludes that climate warming does not always automatically lead to increased plant biomass, invasions of new species and shrubification in tundra,...

Colder US Winters Due To Shifting Polar Jet Stream: Study
2014-02-17 12:39:08

[ Watch the Video: Blame The Jet Stream On Colder Winters ] Brett Smith for redOrbit.com - Your Universe Online Global warming skeptics have pointed to the unusually cold winter in parts of the United States this year as evidence against climate change. However, a new study from Rutgers University indicates that the unusually chilly temperatures in the Midwest and southeastern US are consistent with projections of permanent shifts in weather patterns caused by rising temperatures....

Climate Change Sentinels In The Arctic
2014-02-15 04:47:25

Brett Smith for redOrbit.com - Your Universe Online Being particularly sensitive to carbon monoxide and methane, canaries were often used by miners as sentinels to determine if the toxic mine-related gases were building up to dangerous levels. Speaking this week at the annual meeting of the American Association for the Advancement of Science in Chicago, oceanographer Sue Moore said walruses, polar bears and seals can be looked at in much the same way, in that well-being of these Arctic...

Arctic Biome Under Extreme Threat From A Changing Climate
2014-02-14 10:55:40

Brett Smith for redOrbit.com - Your Universe Online The Arctic as we know it may not exist as climate change is threatening the polar biome’s unique biodiversity and landscape, according to a new report from a large international team of scientists. Conducted by the Conservation of Arctic Flora and Fauna (CAFF) under the Arctic Council, an international forum of Arctic nations, the new study found that climate change could shrink Arctic ecosystems, as advancing changes move north and...

Narwhal for Ice Management Recognized by Panel of E&P Industry Experts HOUSTON, Feb. 6, 2014 /PRNewswire/ -- ION Geophysical Corporation (NYSE:IO) today announced that its new Narwhal(TM) for Ice Management software received a Spotlight on Arctic Technology award, to be presented at the Arctic Technology Conference in Houston on Monday, February 10. The Arctic Technology Conference (ATC) shines the spotlight on the latest innovations in the Arctic E&P industry with its annual...

Polar Bear Diets Change Climate Change
2014-01-23 13:03:52

Lee Rannals for redOrbit.com - Your Universe Online Polar bears are able to switch up their diet in order to help them survive the warming Arctic, according to a new study. Scientists at the American Museum of Natural History performed a three-part study that shows how polar bears switch up plant and animal food sources as they face the changing climate. Arctic sea ice is beginning to melt earlier and freezing later each year, so polar bears are having a limited amount of time to hunt...

Arctic Warmth Reveals Samples Of Ancient Moss
2014-01-21 14:51:23

Wiley When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming. Since the moss samples would have been destroyed by erosion had they been previously exposed, the authors suggest that the temperatures in the Arctic are...

Mercury In Arctic Russian Rivers On The Decline
2013-12-21 05:37:36

April Flowers for redOrbit.com - Your Universe Online Researchers have assumed for years that high and increasing levels of mercury in the North American and European Arctic means the same is true of fish elsewhere in the Arctic. A team of researchers from the US, Russia, and Canada, however, has discovered that in much of the continental Arctic, that assumption is misguided. Differences in mercury processes occur because of diverse atmospheric, geological, and biological conditions....

Amphipod Species Moving Into Arctic Waters
2013-12-19 09:04:00

redOrbit Staff & Wire Reports - Your Universe Online Amphipods typically found in the Atlantic Ocean are now reproducing in the Arctic waters west of Spitsbergen, Norway, and according to research appearing in the journal Marine Ecology Progress Series, the discovery could signify a shift in the region’s zooplankton community. The presence of these creatures was discovered by biologists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), who...

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...
