Model Provides Successful Seasonal Forecast For The Fate Of Arctic Sea Ice
2011-09-23 03:44:18

  Relatively accurate predictions for the extent of Arctic sea ice in a given summer can be made by assessing conditions the previous autumn, but forecasting conditions more than five years into the future depend on understanding the impact of climate trends on the ice pack, new research shows. Current conditions form an important starting point that governs how the ice responds to weather in the course of a few years, University of Washington-led research shows. But eventually...

Bowhead Whales Use Northwest Passage To Migrate
2011-09-22 12:44:41

   According to research published in the journal Biology Letters, bowhead whales are using the Northwest Passage to move across the top of the Americas. Scientists analyzed skeletons, DNA samples and harpoon heads and found these giants of the Arctic living on each side of the continent did meet and mingle. Mads Peter Heide-Jorgensen from the Greenland Institute of Natural Resources and colleagues satellite-tagged over 100 bowheads over the last decade. The researchers...

A shipboard expedition off Norway, to determine how methane escapes from beneath the Arctic seabed, has discovered widespread pockets of the gas and numerous channels that allow it to reach the seafloor. Methane is a powerful "greenhouse" gas and the research, carried out over the past week aboard the Royal Research Ship James Clark Ross, will improve understanding of its origins in this area, its routes to the sea floor and how the amount of gas escaping might increase as the ocean warms....

Arctic Sea Ice At Second-lowest Level Since 1979
2011-09-16 04:32:17

  The extent of Arctic Ocean sea ice fell to its second-lowest size since 1979, the U.S. National Snow and Ice Data Center (NSIDC) said on Thursday. According to preliminary findings, the annual sea ice minimum was reached on September 9, when the ice covered 1.67 million square miles, the center said in a statement. "Changing winds could still push ice flows together reducing ice extend further," the researchers said. A full analysis will be available early next month, when...

Image 1- Arctic Ice Closes In On Record Low

  A new record low could soon be set for ice in the Arctic. The past five years have seen the lowest extent of sea ice since satellite measurements began in the 1970s. Earth observing satellites make it possible to measure the amount of sea ice in inaccessible areas such as the Arctic. This year, the extent of Arctic sea ice is comparable to the record low set in 2007. According to scientists at the University of Bremen in Germany, sea ice extent in early September has...

Arctic Sea Ice Extent Hits Record Low

  The area covered by Arctic sea ice during the summer reached a new all-time low on Thursday, with the summer sea ice extent falling to 1.64 million square miles (4.24 million square kilometers), scientists from a German university reported on Friday. According to AFP reports on Saturday, the current level is approximately one-half a percent below the previous record low, which dates back to the first satellite observations in 1972. Researchers at the University of Bremen's...

  A new report from the European Space Agency (ESA) shows that sea ice in the Arctic Ocean has receded dramatically during this summer, opening up two new shipping lanes - the Canadian Northwest Passage and Russia´s Northern Sea Route. The summer of 2007 recorded the lowest amount of sea ice since satellite observations began in 1979. That season was hit with unusual weather; skies opened over the central Arctic Ocean and wind patterns pushed warm air into the region,...

  Denmark - along with Greenland and the Faroe Islands, part of the Kingdom of Denmark - is looking to put itself on a collision course with four other nations, the United States, Russia, Norway, and Canada. All five countries are trying to lay claim to the Arctic Seabed, including the area around the North Pole. The document, called the Joint Arctic Strategy for 2011-2020 of the Kingdom of Denmark, was signed by Danish Foreign Minister Lene Espersen, Prime Minister of the Faroe...

  You can´t get any “higher”: on 22 August 2011 at exactly 9.42 a.m. the research icebreaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association reaches the North Pole. The aim of the current expedition is to document changes in the far north. Thus, the researchers on board are conducting an extensive investigation program in the water, ice and air at the northernmost point on the Earth. The little sea ice cover makes...

The U.S. Geological Survey (USGS) said Thursday that it would attempt to attach 35 satellite radio-tags to walruses on the northwestern coast of Alaska as part of an ongoing study into how the mammals are responding to reduced Arctic sea ice conditions during late summer and fall. The fast-melting Arctic sea ice seems to be pushing the walruses out onto land, with many moving near the area where oil leases have been sold, the agency said. "Sea ice is an important component in the life...

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...
