Weddell Sea, an arm of the Atlantic Ocean off the coast of Antarctica. It lies south of the Antarctic Circle, largely between the Antarctic Peninsula and Coats Land. Most of the sea, especially in the south, is covered by huge sheets of ice, the largest of which are the Ronne, Filchner, and Larsen ice shelves. Many scientific research stations are located along the Antarctic Peninsula. The Weddell Sea was discovered by the British navigator James Weddell in 1823.

Antarctica, the ice-locked landmass around the South Pole. The name means "opposite the Bear" (the northern constellation), or "opposite the Arctic." It is the most remote and desolate of all the continents.
