Physico-chemical characteristics and postglacial desalination of Stanwell–Fletcher Lake, Arctic Canada
Stanwell–Fletcher Lake is a cold monomictic Arctic lake, essentially isothermal at about 1.5 °C, with almost complete ice cover throughout the year. The annual heat input is about 13 000 cal cm −2 , much less than that of dimictic Arctic lakes. The lake is isochemical, with very low ionic concentrat...
