Beaufort Sea

 

a sea bordering the Arctic Ocean on the shores of North America between Point Barrow and the shores of the Canadian Arctic Archipelago. Area, 476,000 sq km. Maximum depth, 4,683 m; average depth, 1,004 m. For the most part the Beaufort Sea covers the continental shelf. The currents form a cyclone-like vortex. In August on the southern periphery of this vortex motion, water that is heated to a temperature of 4° C and has a salinity of about 28 parts per thousand is carried eastward; on the northern periphery, arctic water with a temperature of 1.5° C and salinity of about 32 parts per thousand is carried westward. The Beaufort Sea is covered all year by ice; the ice edge retreats to a distance of 50–100 km from the shore in August. The Mackenzie River empties into the Beaufort Sea. The sea was named for the English admiral F. Beaufort.
