Ancient Antarctic rivers challenge theory of a flat landscape, as mission for climate clues beneath Antarctic ice gets underway

Source: Imperial

Pre-glacial West Antarctica was a rugged, uneven landscape, not a flat plain, reshaping our understanding of how its ice sheet first formed and how it may behave in a warming climate, a new study led by Imperial College London has revealed.

This comes alongside the news – announced today – that an international team, also involving Imperial, has recently set up a remote camp on the ice in Antarctica to attempt to drill for mud and rocks that hold critical insights about the fate of the West Antarctic Ice Sheet due to climate change.

Scientists Drilled Into Antarctic Ice Until They Met Bedrock, Then Got A 228-Meter Sample Of Sediment

Scientists have just got their hands on a 228-metre (748-foot) core sample from the muddy bedrock beneath West Antarctica’s chunky ice sheets. Inside the record-breaking sample, they discovered fossils of marine organisms that date from a time when this area was an open, ice-free ocean.
