Antarctic Circumpolar Current

We just learned about the Nunatuk rock formations.

Another part of Antarctica is the Antarctic Circumpolar Current, also called the ACC.

In the ocean around Antarctica the water flows around it in a clockwise loop.

This water flow called a current is the largest ocean current in the world, mostly because it flows around and around without hitting any other land.
Most other ocean currents eventually run into other continents.

The looping current goes around Antarctica and the south pole like a circle, which is why it's called "Circumpolar".
With the water going around and around, it helps keep the warmer ocean water from getting to Antarctica.
This helps keep the south pole cold and the glaciers from melting.
