Antarctic Coastline Images Reveal Four Decades of Ice Loss to Ocean

Part of Antarctica has been losing ice to the ocean for far longer than had been expected, satellite pictures reveal. A study of images along 2000km of West Antarctica’s coastline has shown the loss of about 1000km2 of ice – an area equivalent to the city of Berlin – over the past 40 years. Researchers

AWARE Project Launched to Gain New Insights on Climate of Antarctica

It has been nearly half a century since scientists have collected extensive climate or atmospheric data from the West Antarctic Ice Sheet (WAIS). But late last year, scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, working with a group led by the Scripps Institution of Oceanography, embarked on a new project that

The Geography of Antarctica’s Underside

December 11, 2015 — Planetary scientists would be thrilled if they could peel the Earth like an orange and look at what lies beneath the thin crust. We live on the planet’s cold surface, but the Earth is a solid body and the surface is continually deformed, split, wrinkled and ruptured by the roiling of warmer

GOCE Reveals Gravity Dip from Ice Loss

Although not designed to map changes in Earth’s gravity over time, ESA’s extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature. The strength of gravity at Earth’s surface varies subtly from place to place owing to factors such as the planet’s rotation and the

Cryosat Finds Sharp Increase in Antarctica’s Ice Losses

Three years of observations from ESA’s CryoSat satellite show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year – twice as much as when it was last surveyed.
