Latest West Antarctic Ice Sheet Stories
As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away.
Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions.
The seas are creeping higher as the planet warms.
A team of four British Antarctic Survey (BAS) engineers has returned to the UK after completing a grueling journey to one of the most remote and hostile locations on the planet to put in place equipment and supplies for an ambitious project later this year.
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.
Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface.
Scientists with NASA's Operation IceBridge airborne research campaign began the mission's third year of surveys this week over the changing ice of Antarctica.
An Antarctic lake hidden under 1.8 miles of ice in the western region of the continent could reveal what life on Earth looked like a million years ago and could narrow down the search for extraterrestrial life.
An analysis of prehistoric "Heinrich events" that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice shelves.
