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...

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
2011-09-11 04:01:00

  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,...

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...

In three decades of recording Arctic Ocean sea ice, the National Oceanographic and Atmospheric Administration (NOAA) on Monday reported that in July 2011 the sea ice hit its lowest monthly recorded level. Sea ice in the Arctic covered an average 3 million square miles during July, the lowest measurement for that month since the NOAA started keeping such records in 1979. The July 2011 figure is 81,000 square miles smaller than 2007's July record low and about 22 percent below the average for...

The melting of Arctic sea ice may temporarily stabilize, and the ice may even expand, over the coming years, according to new research by scientists at the National Center for Atmospheric Research (NCAR). "As we learn more about climate variability, new and unexpected research results are coming to light," said Sarah Ruth, program director in the Division of Atmospheric and Geospace Sciences, which funds NCAR. "What's needed now are longer-term observations to better understand the effect of...

According to MIT researchers, the most recent global climate report fails to capture the reality of the changing Arctic seascape. The researchers said the most recent global climate report fails to capture trends in Arctic sea-ice thinning and drift, and in some cases substantially underestimates these trends.  The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report estimates that an ice-free Arctic summer by the year 2100. However, Pierre Rampal, a postdoc in...

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...
