Climate Change May Be Indirectly Threatening Caribou In The Arctic
2013-10-01 14:04:59

Lee Rannals for redOrbit.com - Your Universe Online New research indicates that caribou may be indirectly affected by climate change due to sea-ice loss in the Arctic. Researchers, publishing a paper in the journal Nature Communications, say that melting sea ice is leading to fewer caribou calf births and higher calf mortality in Greenland. The team was able to link the melting Arctic sea ice with changes in the timing of plant growth on land, which in turn led to lower production of...

Pleistocene Ice Sheet Evidence Uncovered
2013-10-01 04:53:02

April Flowers for redOrbit.com - Your Universe Online Traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia have been discovered by a team of geologists and geophysicists from the Alfred Wegener Institute (AWI) Helmholtz Centre for Polar and Marine Research. For the first time, these traces confirm that within the last 800,000 years in the course of ice ages, ice sheets more than approximately a mile thick also formed in the Arctic Ocean....

Long-term Data Reveal Deep Greenland Sea Warming Faster Than The Global Ocean
2013-09-25 12:53:48

Alfred Wegener Institute Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters. For their study, they analyzed  temperature data from 1950 to 2010 in the abyssal Greenland Sea, which is an ocean area located just to the south of the Arctic Ocean....

Arctic Sea Ice Minimum For 2013 Sixth Lowest On Record
2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

Climate Woes Continue: Changes In Polar Bear Diet Result In Higher Toxin Exposure
2013-09-20 12:34:08

Brett Smith for redOrbit.com - Your Universe Online Warmer than average Arctic temperatures in recent years have been stirring up all kinds of ecological changes and a new study in the journal Global Change Biology indicates that polar bears could be getting exposed to higher levels of toxins as a result. The study looked at an East Greenlandic population of polar bears, which is expected to enjoy the Arctic sea ice far longer than other regions. However, the loss of ice sheet cover in...

Global Warming Could Explain Exponential Sea Ice Growth
2013-09-18 12:28:55

Michael Harper for redOrbit.com - Your Universe Online In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National...

ESA’s CryoSat Mission Provides New Insights Into Our Fragile Polar Regions
2013-09-11 11:48:06

[ Watch The Video - Arctic Ice Thickness 2010 to 2013 ] ESA Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin. Although satellites have witnessed a downward trend in the extent of sea ice over the last two decades, it is essential to have accurate information on the mass or volume of ice being lost. This is a more accurate measure of the...

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...
