Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

Greenland without its ice sheet looks like a big bath tub. Inside the ringing mountain ranges, the ice, covering 85% of Greenland, is a mile thick (1.7 km) on average.
The weight of this massive layer of frozen freshwater pushes down on the land, meaning the bedrock is mostly under sea level.
