The Antarctic Current completed millions of years after the continent froze. The Circumpolar Current, with a front of up to 2,000 kilometers, connects the Atlantic, Indian and Pacific oceans.

It is the strongest current in the world and connects all oceans. “This has global implications for the climate of our planet,” says Dimitris Evangelinos, researcher at Imperial College London and Imperial University of Barcelona. The current thermally separates Antarctica and protects all the ice it houses.
