Lee Rannals for redOrbit.com - Your Universe Online Scientists believe they have discovered a hidden rift valley that may be contributing to ice loss in West Antarctica. University of Aberdeen and British Antarctic Survey (BAS) experts made the discovery below Ferrigno Ice Stream, which is a very remote region that has only been visited once before. The team has reveled that the ice-filled ancient rift basin is connected to the warming ocean, which impacts ice flow and loss. The...

Antarctica Ice Sheet May Begin Melting Rapidly By Century's End
2012-05-09 13:58:16

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century. The finding, made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, refute a widely believed theory that ice shelves in the Weddell Sea would not be affected by global warming due to the peripheral location of the sea. "The Weddell Sea was not really on the screen because we all thought that unlike the Amundsen...

Image 1 - West Antarctic Ice Shelves Tearing Apart at the Seams

[ Watch the Video ] A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea. The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or...

Operation IceBridge: Flying Through A Crack On The Ice
2012-03-01 10:19:05

[ Watch the Video ] In October 2011, researchers flying in NASA´s Operation IceBridge campaign made the first-ever detailed, airborne measurements of a major iceberg calving event while it was in progress. Four months later, the IceBridge team has mapped the crack in Antarctica´s Pine Island Glacier in a way that allows glaciologists and the rest of us to fly through the icy canyon. The above image is a still frame captured from a three-dimensional, virtual flight through the...

Spectacular Photos Show Birth Of World’s Biggest Iceberg

[ Watch the Video ] Breathtaking images taken from outer-space by NASA's Operation IceBridge -- the largest airborne survey of Earth's polar ice ever flown -- reveal a 19-mile long, 195 ft.-deep crack across a floating ice shelf in Antarctica that could produce the world´s largest iceberg. The rift was first discovered last October, but IceBridge scientists returned soon after to obtain the first-ever detailed airborne measurements of the 310 square mile iceberg calving in...

Climate change effects to be monitored with new fiber-optic distributed temperature sensing Half-mile long thermometers have been dropped through the Ross Ice Shelf in Antarctica that will give the world relevant data on sea and ice temperatures for tracking climate change and its effect on the glacial ice surrounding the continent. The study based at the University of Nevada, Reno is funded by the National Science Foundation's Office of Polar Programs and other NSF grants. "This...

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according to new University of Washington research. Higher-than-normal sea-level pressure north of the Amundsen Sea sets up westerly winds that push surface water away from the glaciers and allow warmer deep water to rise to the surface under the edges of the glaciers, said...

Researchers To Drill Beneath Massive Antarctic Ice Shelf
2011-11-10 04:49:24

[ Watch the Video ] An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea. The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists...


Word of the Day
ambsace
  • Bad luck; misfortune.
  • The smallest amount possible or the most worthless thing.
The word 'ambsace' comes from a Latin word meaning 'both'.
