Abstract

Theoretical aspects of the influence of the temperature of maximum density of water on the circulation of deep cold lakes are applied to the temperature structure of Great Bear Lake. In general good agreement between observation and theory is found. In most years summer circulation does not extend below a depth of 225 m as stability at lower levels is sufficient to prevent it. In cold years with slow heating, circulation extends to the bottom (450 m). In winter the lower half of the lake is isothermal at the temperature of maximum stability (3.53 C) of the bottom water. This is explained on the basis of the slope of the line of maximum density being double that of the slope of the line of maximum stability. When the water at a depth of 225 m is cooled to 3.53 C the point of maximum temperature in the profile at this depth is removed so that isothermy develops in the lower half of the lake.
