Both the Pacific and Atlantic Oceans have northern and southern regions with differing circulating patterns. Africa is the western boundary of the Indian Ocean and Australia forms its eastern boundary. The Indian Ocean lies mainly in the southern hemisphere. The Arctic Ocean lies near the North Pole. The land regions of Alaska, Canada, Greenland, Russia and Scandinavia almost completely surround the Arctic Ocean.
