Analyses will help to reveal how far the West Antarctic Ice Sheet retreated in the past — and what it might do in the future.

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.

Under bone-chilling conditions, an international team of scientists has unlocked the secrets to better understand a rapidly-warming planet.

Ein Forschungsteam hat einen 228 Meter langen geologischen Bohrkern von unter dem antarktischen Eis zu Tage gebracht. Es handelt sich um die erste derart umfassende Bodenprobe. Anhand der Sedimentschichten soll ablesbar sein, bei welchen Temperaturen das westantarktische Eis schmilzt.

The magic moment looked strangely domestic for a gathering of scientists and drillers working in freezing temperatures on the massive Ross Ice Shelf.

After three attempts, the New Zealand co-led international effort to dig 500 metres below the West Antarctic Ice Sheet has managed to recover sediment that's millions of years old.

An Antarctic sediment sample dating back millions of years shows evidence that a major ice sheet partially or totally collapsed during a previous warm period.

The 748-foot-long sediment core contains a record of roughly the past 23 million years, including periods when the planet’s surface temperature was hotter than it is today
