Voyage to the Edge of the World.

On his ship "Calypso," as well as in a submarine, Jacques Cousteau and his crew sail from South America and travel to Antarctica. They explore islands, reefs, icebergs, fossils, active volcanic craters, and creatures of the ocean never before seen. This voyage took place in 1975, and Captain Cousteau became one of the first explorers ever to dive beneath the waters of the frozen South Pole.
