Beaufort Sea The Beaufort Sea () is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea shores. The sea, characterized by severe climate, is frozen over most of the year. Historically, only a
Lincoln Sea Ocean waters flow counterclockwise (cyclonically) along the northern shores of Canada, passing through the Lincoln Sea. Atlantic Ocean waters cyclonically flow in from and return to the Eurasian basin along the Greenland Sea continental slope. The waters of these basins converge at the Lincoln Sea, creating unique vertical temperature and salinity profiles here. Measurements detail that both the Pacific and Eurasian Ocean water profiles are clearly offset from one another, an important facet of the hydrography of the Lincoln Sea. The Lincoln Sea has been found to contain water with three distinct properties. The first concerns the water in the
