We just learned about the Filchner-Ronne Ice Shelf.
Another part of Antarctica is the Weddel Sea.
This is the water just to the East of the Antarctic Peninsula.
Some scientists believe this to be the clearest sea water in the whole world, and people have been able to see things down in the water over 250 feet deep.
The sea is about 1,200 miles across, and some sailors have said that it was the most dangerous sea on earth.
As people have taken their boats into this sea, sometimes the ice will flash freeze, and then melt again, and sometimes the ice will crush or tip over ships.
There are many animals who live in this sea, like the Weddell seal, killer whales, humpback whales, minke whales, leopard seals and crabeater seals.
There are also some penguins that live on the land in this area and swim in the sea.
