The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). The findings raise concerns about the thawing of permafrost, or permanently frozen soil, and the potential consequences for sensitive ecosystems, human infrastructure, and the release of additional greenhouse gases."Our study suggests that, if sea-ice continues to contract rapidly...

Scientists warned on Friday that they expect climate change to begin affecting the Antarctic, as the pace of thinning ice in the Arctic continues."The long-term prognosis is not very optimistic," Jennifer Francis, an atmospheric scientist with Rutgers University said during a briefing.In a shift many attribute to climate change, sea ice in the North shrank to a record low last summer. Although levels of solar radiation and greenhouse gases are similar at each of the planet's poles, the...

The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. The study, by scientists at the National Center for Atmospheric Research (NCAR) and Colorado State University (CSU), finds that unusually sunny weather contributed to last summer's record loss of Arctic ice, while similar weather conditions in past summers do not appear to have had comparable impacts.The study, which draws on observations from instruments on a new group of NASA...

Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did in previous decades, NASA scientists announced today in an update of the states of Arctic and Antarctic sea ice. March is the month where Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest extent. NASA satellites have monitored sea ice coverage over both poles for nearly 40...

Arctic sea ice that re-formed after last summer's melt should be seen as an illusion rather than a new hope, according to Walter Meier of the National Snow and Ice Data Center.By glancing at a satellite image of the area, one could easily assume that the ice is making a comeback. Meier said the ice became more vulnerable after being melted and frozen."What's going on underneath the surface is really the key thing," Meier said. Having formed since September, more than 70 percent of the sea ice...

Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for several years has continued to decline. On March 18 the scientists said they believe that the increased area of sea ice this winter is due to recent weather...

MADISON - The pending federal decision about whether to protect the polar bear as a threatened species is as much about climate science as it is about climate change. The U.S. Fish and Wildlife Service (FWS) is currently considering a proposal to list the polar bear as a threatened species under the Endangered Species Act, a proposal largely based on anticipated habitat loss in a warming Arctic. Climate models - mathematical representations of the natural processes affecting climate -...

Scientists recently developed a new modeling approach to estimate sea ice thickness. This is the only model based entirely on historical observations. The model was developed by scientists with the U.S. Geological Survey and the Russian Academy of Sciences, Moscow. Using this new technique, the thickness of Arctic sea ice was estimated from 1982 to 2003. Results showed that average ice thickness and total ice volume fluctuated together during the early study period, peaking in the late 1980s...

New evidence could solve the puzzle of why Antarctica went into the deep freeze A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. Ice sheet formation in the Antarctic is one of the most important climatic shifts in Earth's history. However, previous temperature...

Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2007 tied with 1998 for Earth's second warmest year in a century. Goddard Institute researchers used temperature data from weather stations on land, satellite measurements of sea ice temperature since 1982 and data from ships for earlier years. The greatest warming in 2007 occurred in the Arctic, and neighboring high latitude regions. Global warming has a larger affect in polar areas, as...

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...
