We just learned about the Ross Sea.
Another part of Antarctica is Marie Byrd Land.
This is part of West Antarctica, and it is about 620,000 square miles.
A lot of parts of Antarctica have research stations or areas where countries of the world have said they own, but this part of Antarctica is not owned by anyone.
Because of this it is the biggest piece of land in the whole world that is not owned by anyone.
There have been some camps set up out in the middle of this land area to try and study it, and usually to try and drill very far down into the ice to see what it is like far below the surface.
