"Beneath Antarctica’s Ross Ice Shelf lies one of the least measured oceans on
Earth – a vast, dark cavity roughly twice the volume of the North Sea.

This hidden ocean matters because it is the ice sheet’s Achilles heel. The ice
sheet is the continent’s enormous, kilometres-thick mass of land-based ice,
while the ice shelf is the floating platform that fringes it.

If warmer water reaches the underside of the shelf, it can melt the ice that
holds back millions of cubic kilometres of Antarctic ice, with consequences for
global sea levels.

Yet almost everything we know about this cavity has come from brief snapshots
at its edges. Until now, no one had captured a long, continuous record from its
central heart. Our newly published study set out to change that."
