NASA's first dedicated oceanographic field campaign goes to sea next week to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change. The ICESCAPE mission, which stands for "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas along Alaska's...

NASA will hold a media teleconference at 1 p.m. EDT on Tuesday, June 8 to preview the agency's first dedicated oceanographic research voyage. During the mission, scientists will study changing Arctic climate and ice conditions affecting ocean ecosystems. The "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment" mission, or ICESCAPE, will investigate how climate change in the Arctic may be altering the ocean's ability to absorb carbon from the atmosphere. The...

The U.S. National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records. The center said in a statement on Wednesday that cold weather and winds from the north over the Bering Sea and Barents Sea meant the area of ocean covered by ice expanded through last month.  That is two days later than in 1999, the previous latest start to a melting...

Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere. The researchers' findings "“ published on-line today in Nature Geoscience "“ provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial...

A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages may have been higher than previously thought A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. The findings, reported this week by...

Remains On Downward Trend Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. According to the CU-Boulder center, the 2009 minimum sea ice extent was the third lowest since satellite record-keeping began in 1979. The past five...

CU-Boulder's Snow and Ice Data Center analysis shows negative summertime ice trend continues The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. While this year's September minimum extent was greater than each of the past two record-setting and near-record-setting low years, it is still...

U.S.-led scientists conducting an ecosystem study of arctic warming say they've determined the arctic, as we know it, might soon be a thing of the past. The international team, led by Penn State University Associate Professor Eric Post, carried out studies of the biological response to arctic warming during the fourth International Polar Year that ended in 2008 and documented a wide range of responses by plants, birds, animals, insects and humans living in the region. Post said his team...
