24 percent of West Antarctic ice is now unstable: study

By combining 25 years of European Space Agency satellite altimeter measurements and a model of the regional climate, the UK Centre for Polar Observation and Modelling (CPOM) have tracked changes in snow and ice cover across ...

Snow over Antarctica buffered sea level rise during last century

new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes ...

The Pine Island Glacier in Western Antarctica is not only one of the fastest-flowing ice streams in the Southern Hemisphere; over the past 11 years, four major icebergs have calved from its floating tongue. In February 2017, ...

Antarctic seals can help predict ice sheet melt

Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica.

Antarctica retreating across the sea floor

Antarctica's great ice sheet is losing ground as it is eroded by warm ocean water circulating beneath its floating edge, a new study has found.

Giant West Antarctic iceberg disintegrates
