ON THE WATER OF TUKTOYAKTUK HARBOUR

Describes major features of the 1962-63 temperature and salinity data collected from the ice cover and aboard M/V Richardson in Kugmallit Bay and Tuktoyaktuk harbor in eastern Mackenzie Delta in connection with the operation of an airbubbler system. A rough winter energy budget of the water with and without an ice cover is given, water exchange between the bay and harbor due to summer estuarine and winter tidal mechanisms is suggested, and the significance of conditions in the seaward approach discussed. During the summer season ice and snow melt and runoff, an estuarine type of circulation occurs, comprising a seaward flow of a mixed fresh and salt water surface layer and a compensating subsurface salt water flow into the harbor. With an ice cover, a tidal effect brings freshwater from the bay into the harbor to increase the depth of a freshwater layer and to decrease the salinity at depth below an intense halocline.
