The Arctic Ocean
To some people, the waters around the North Pole are a part of the Atlantic, mainly because they are joined to the Atlantic Ocean by a broad stretch of sea between Scandinavia and Greenland. However, most oceanographers call these waters the Arctic Ocean. This is the smallest and shallowest of the four oceans. More than thirteen oceans of its size would fit into the Pacific basin and the Arctic Ocean's average depth is only one quarter that of the Pacific.
