Includes bibliographical references (pages 79-82). "The south Beaufort Sea, immensely modified by the outflowing Mackenzie River, consists of a layer of low salinity water of Mackenzie River origin overlying one of higher salinity, of offshore, Arctic Ocean origin. The variable balance between these elements determines the extent of the river plume, and therefore the basic biological composition of the south Beaufort Sea. A changing sea ice cover influences undersea light and provides a surface for the ice flora which supplies a primary food source for what appears to be an important trophic series"--Summary.
