After nearly a year and a half of operations, CryoSat has yielded its first seasonal variation map of Arctic sea-ice thickness. Results from ESA’s ice mission were presented Tuesday at the Royal Society in London.

Scientists Concerned About Methane, Fishing In Arctic Ocean

While some scientists encouraged the creation of regulations governing fishing in the Arctic Ocean on Sunday, others published a report warning that the body of water could actually be a significant source of the greenhouse gas methane.

Ocean Found To Be Surprising Source Of Arctic Methane

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...

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...
