The Pacific Ocean is the largest and deepest of Earth’s five oceanic divisions, stretching from the Arctic Ocean in the north to the Southern Ocean in the south, and bounded by Asia and Australia in the west and the Americas in the east.
At 165,250,000 square kilometres in area, the Pacific covers approximately 46 per cent of Earth’s water surface and about 32 per cent of the planet’s total surface area, larger than all of Earth’s land combined. Its mean depth is 4,000 metres, and it contains the deepest known point in the world: the Challenger Deep in the Mariana Trench, at 10,928 metres. Ocean circulation divides it into the North Pacific and South Pacific, which meet at the Equator. Major marginal seas include the Philippine Sea, South China Sea, Bering Sea, Gulf of Alaska, Tasman Sea and Coral Sea. The oceanic pole of inaccessibility—the point in the ocean farthest from any land—lies in the Pacific.
The Pacific features in the episode with Cyril Derreumaux, who kayaked solo across both the Pacific and the Atlantic.
