Over the 23 years whose data was analyzed by researchers, ice shelves in the Amundsen Sea
sector gained more height from snowfall than the loss suffered due to melting underwater as warm water flowed under them.
In the past couple years, a couple papers have said that retreat of grounding lines in the Amundsen Sea
Starting in November this year the iSTAR science programme will mount four projects focused on finding out what's causing the rapid changes observed in the Amundsen Sea
region of the West Antarctic Ice Sheet.
In the Amundsen Sea
coastal region where Criscitiello works, winds are driving warming deep-ocean waters onto the continental shelf and beneath the ice shelves extending from glaciers into the ocean.
The Amundsen Sea
Embayment, one of the three major ice drainage basins of the West Antarctic ice sheet, is also causing concern.
Snapshots of ice thickness as colors with superimposed surface elevations as contour lines are shown at 100, 500, 1000, 1750 and 2000 years, with retreat starting at 100 years, driven by increased thinning at the grounding line, a result of warmer ocean temperatures in the Amundsen Sea
Similar studies of glaciers entering the Amundsen Sea
, some 1,200 miles away in West Antarctica, show them doubling their flow since the 1990s.
Around the Amundsen Sea
, we have surveyed a half dozen glaciers.
Some glaciers in Antarctica are flowing more quickly to the sea, with ominous potential implications for worldwide sea levels A paper in the online edition of the journal Science said glaciers flowing into the Amundsen Sea
were thinning twice as quickly as they were in the 1990s.
Those flowing into the Amundsen Sea
alone are discharging 60 per cent more ice than they accumulate.
ANTARCTIC: A 233-squaremile iceberg (about 25 miles long and nine miles wide) has broken off the Pine Island Glacier in the Antarctic and is drifting north-west in the Amundsen Sea
, the National Ice Centre reported yesterday.
The sediment cores studied by the researchers were collected from Pine Island Bay in the Amundsen Sea
