200 metres of sediment core!

Third time’s a charm - we have successfully drilled 200 metres of sediment core from beneath the ice sheet at Crary Ice Rise!

This massive achievement is three seasons in the making, and many more years in the lead-up to our team reaching the ice. It's the culmination of the hard work of our large team of scientists, drillers, engineers and Antarctic logistics specialists.

We’re excited about the science to come, and the insights about the past and future of the West Antarctic Ice Sheet waiting in the core, but for now we want to celebrate our drill team for delivering this massive technological feat. 

The pipe is still spinning - with a bit of time in the field still up our sleeve, we’re not stopping drilling yet, as we continue to drill back through the geological archive hidden beneath the ice.

The day shift took the glory with this one, but it is equally shared with our night-shift crew who work in the shade through cold temperatures.

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

18 February 2026

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.
