We just learned about the Antarctic Circumpolar Current.
Another part of Antarctica is the Antarctic Convergence, also called the Antarctic Polar Front.
This is the line in the water around Antarctica where the cold water of Antarctica meets the warm water from the rest of the oceans.
Where the waters meet the cold water usually sinks down below, and the warm water goes to the top.
Because of this mixing, a lot of sea animals like krill live there, which also means a lot of other animals that eat krill come around.
The mixing of this cold and warm water has a lot of effects on the rest of the ocean.
