Why Antarctic ice shelves are losing their mass and how it leads to global sea level rise

OCEANOGRAPHY
The Greenland ice sheet (GIS) and Antarctic ice sheet (AIS) contribute largely to global mean sea level (GMSL) changes, though the seas surrounding the...

‘Devastating’ melt of Greenland, Antarctic ice sheets found

EARTH
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago,...

Massive Australia wildfires increased Antarctic ozone hole: Study

ENVIRONMENT
Smoke from monster wildfires in Australia caused a chemical reaction that widened the ozone hole 10 percent, researchers said Wednesday, raising fears that increasing...

How thick is Antarctic ice, and what is underneath?

OCEANOGRAPHY
Ice at the edge of the Antarctic continent hosts a flourishing ecosystem. Seals and penguins breed, fish mature, and algae thrive, all thanks to...

Drilling campaign reaches a depth of 808 meters in the Antarctic ice sheet

OCEANOGRAPHY
In Antarctica, the second drilling campaign of the Beyond EPICA—Oldest Ice project, at the remote field site Little Dome C, has been successfully completed....

Vast iceberg breaks off near UK Antarctic base

OCEANOGRAPHY
A huge iceberg nearly the size of Greater London has broken off the Antarctic ice shelf near a research station, the second such split...

Runaway West Antarctic ice retreat can be slowed by climate-driven changes in ocean temperature

OCEANOGRAPHY
New research finds that ice-sheet-wide collapse in West Antarctica isn't inevitable: the pace of ice loss varies according to regional differences in atmosphere and...

Study identifies new cause of melting Antarctic ice shelves

OCEANOGRAPHY
Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent...

Scientists expose vulnerabilities of critical Antarctic ice shelf

OCEANOGRAPHY
Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to...

Record of Antarctic ice sheet response to climate cycles found in rock samples

OCEANOGRAPHY
By analyzing unusual rock samples collected years ago in Antarctica, scientists at the University of California, Santa Cruz, have discovered a remarkable record of...

A swarm of 85,000 earthquakes at the Antarctic Orca submarine volcano

EARTHQUAKES
Volcanoes can be found even off the coast of Antarctica. At the deep-sea volcano Orca, which has been inactive for a long time, a...

Recent studies find previously unknown loss of Antarctic ice

OCEANOGRAPHY
New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the...
