Why the tongue of the Pine Island Glacier suddenly shrank

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

An animation of the giant iceberg that calved off the Pine Island Glacier in West Antarctica just over two months ago shows an unexpected break up.

Antarctic landscape insights keep ice loss forecasts on the radar

Scientists from the University of Aberdeen have helped carry out a detailed survey of the landscape beneath thick Antarctic ice that researchers say will be a valuable resource in understanding how ice draining into the ocean ...

'Scars' left by icebergs record West Antarctic ice retreat

Thousands of marks on the Antarctic seafloor, caused by icebergs which broke free from glaciers more than ten thousand years ago, show how part of the Antarctic Ice Sheet retreated rapidly at the end of the last ice age as ...

Large iceberg breaks off Pine Island Glacier

Recent satellite images reveal a new 100-square-mile iceberg emerging from Antarctica's Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level ...

Image: Glacial 'aftershock' spawns Antarctic iceberg

Pine Island Glacier has shed another block of ice into Antarctic waters. The loss was tiny compared to the icebergs that broke off in 2014 and 2015, but the event is further evidence of the ice shelf's fragility.

Researchers find seafloor valleys below West Antarctic glaciers

Glaciologists have uncovered large valleys in the ocean floor beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the troughs enable ...
