Giant channels discovered beneath Antarctic ice shelf

Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 metres high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometres along the ice shelf. The channels are likely to influence the stability of the ice shelf and their discovery will help researchers understand how the ice will respond to changing environmental conditions.

Underlying ocean melts ice shelf, speeds up glacier movement

Warm ocean water, not warm air, is melting the Pine Island Glacier's floating ice shelf in Antarctica and may be the culprit for increased melting of other ice shelves, according to an international team of researchers.

Report: Warm ocean causing most Antarctic ice shelf mass loss

Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.

Antarctic ice shelf at tipping point

British and American scientists have discovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet (WAIS) - and say it puts this area of the ice sheet at risk of collapse.

Warm ocean currents behind loss of Antarctic ice

The loss of Antarctic ice is caused mainly by warm ocean currents attacking the underside of ice shelves, a new NASA study has revealed.

Antarctic expedition to drill vulnerable ice shelf

A NASA-funded team of scientists is to drill into a rapidly-thinning Antarctic glacier to try and establish the effect its melting will have on sea levels.

Ridge, not global warming, causing major glacier to melt

In a discovery likely to fan the flames of climate change debate, a team has concluded that the thinning ice on one of Antarctica's major glaciers is not caused by global warming.
