The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. New University of Washington research shows that rising sea surface temperatures in the area of the Pacific Ocean along the equator and near the International Date Line drive atmospheric circulation that has caused some of the largest shifts in Antarctic...

Amundsen Sea Polynya International Research Expedition (ASPIRE) Combines Research and Education In a unique and complex example of "science diplomacy," teams of U.S. and Swedish scientists are sailing this month aboard two research vessels to study the ecology of the Amundsen Sea, one of the least-explored and most productive bodies in Antarctic waters, and to gauge the potential effects of a changing climate on the Southern Ocean. The joint American and Swedish expedition, involving the U.S....

WASHINGTON, Oct. 8 /PRNewswire-USNewswire/ -- NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.

Most comprehensive seabed image of Amundsen Sea Embayment Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise according to a report in the journal Geology this month (May). Using sonar technology from onboard ships, scientists from British Antarctic Survey (BAS) and the German Alfred Wegener Institute (AWI) captured the most extensive, continuous set of images of the seafloor...

A robot submarine studying the underbelly of an Antarctic ice shelf has found evidence of rising sea levels, scientists reported on Tuesday. Developed by UK's National Oceanography Center of Southampton, Autosub is an Automated Underwater Vehicle (AUV). It has completed six missions traveling under Pine Island Glacier, an extension of the West Antarctic ice sheet in the Amundsen Sea. The sub uses sonar to create a three-dimensional map of the seabed and the underside of the ice. Scientists...

British scientists plan to use a yellow submarine to explore beneath a giant melting Antarctic glacier whose collapse could raise sea levels 4 inches. The scientists hope to find out why Pine Island Glacier, flowing west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, is melting so quickly at its base, said the British Antarctic Survey, Britain's national Antarctic operator. The 23-foot-long, robotic yellow submarine, nicknamed Autosub, will map out...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary.
