How Will Climate Change Impact Mammals In Arctic And Sub-Arctic Areas?
2013-01-15 10:36:14

UmeÃ¥ University The climate changes depicted by climatologists up to the year 2080 will benefit most mammals that live in northern Europe´s Arctic and sub-Arctic land areas today if they are able to reach their new climatic ranges. This is the conclusion drawn by ecologists at UmeÃ¥ University in a recently published article in the journal Plos ONE. The scientists Anouschka Hof, Roland Jansson, and Christer Nilsson of the Department of Ecology and...

Ringed And Bearded Seal Species To Be Protected As Endangered Species
2012-12-23 05:55:38

redOrbit Staff & Wire Reports - Your Universe Online Members of two Arctic Seal species will be protected under the Endangered Species Act (ESA) due to vanishing ice and snow in their habitats, officials from the National Oceanic and Atmospheric Administration (NOAA) announced on Friday. The NOAA Fisheries division has declared the Ladoga subspecies of ringed seals, which live in northwest Russia, will be listed as endangered and three others, the Arctic, Okhotsk, and Baltic...

New Twist To Sea Ice Forecasting Brought By NASA's Operation IceBridge Data
2012-12-20 12:57:40

NASA Shrinking Arctic sea ice grabbed the world's attention again earlier this year with a new record low minimum. Growing economic activity in the Arctic, such as fishing, mineral exploration and shipping, is emphasizing the need for accurate predictions of how much of the Arctic will be covered by sea ice. Every June, an international research group known as the Study of Environmental Arctic Change (SEARCH) publishes a summary of the expected September Arctic sea ice minimum known as the...

Arctic Is Changing Before Our Eyes
2012-12-07 05:07:03

Lee Rannals for redOrbit.com - Your Universe Online The 2012 Arctic Report Card was released on Thursday, showing a record low snow coverage and record low sea ice extent. The report card calls on the expertise of 140 scientists from 15 countries to summarize the state of the Arctic. Martin Jeffries of the Office of Naval Research warns that "if we are not already there, we're clearly on the verge of seeing a new Arctic." The report shows a longer growing season with greener...

Oil Companies Work In Extreme Conditions
2012-11-26 11:49:18

University of Stavanger The northward shift of Norway's oil industry means it must adjust to temperatures down to -30°C, storms, sleet and snow, and drift ice; and to the blackest night "Try to imagine changing a tyre in freezing weather, snow and darkness," says professor Tore Markeset, a specialist in cold climate technology at the University of Stavanger (UiS). That is his way of visualizing the challenges facing oil companies seeking to produce oil and gas from the far north...

Ocean Currents Helps Predict Arctic Sea Ice
2012-11-21 15:07:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT have developed a new method for optimally combining models and observations of the Arctic Ocean to accurately simulate the seasonal extent of the ice change and the ocean circulation beneath. The Arctic Ocean freezes each winter to form sheets of sea ice that spread over millions of square miles. This ice then acts as a massive sun visor for the Earth and helps to reflect solar radiation and shield the planet from...

Sea Levels Rising Fast
2012-11-02 08:28:50

April Flowers for redOrbit.com - Your Universe Online Global warming is causing sea levels to rise faster than previously expected and geologist Bill Hay from the University of Colorado Boulder has a theory to explain why. The most recent IPCC report released in 2007 projected a global sea level rise between 0.2 and 0.5 meters by 2100, but current sea level measurements meet or exceed the high end of that range. This suggests a rise of one meter or more by the end of the century....

Ice Caps Grow and Shrink
2012-10-24 20:26:45

Brett Smith for redOrbit.com — Your Universe Online Over the past few years, researchers have consistently shown an overall decrease in the size of the Arctic ice cap–particularly during the summer months when the most melting occurs. However, a new study from NASA scientists has shown that this melt off around the Arctic is accompanied by the record expansion of sea ice around Antarctica, when the Southern Hemisphere is experiencing its colder temperatures of the year....

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
2013-04-18 22:31:23

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...
