Physical and Chemical Limnology of Char Lake, Cornwallis Island (75° N Lat.)
Seasonal data for several physical and chemical variables in Char Lake are given. Annual cycles of major solutes are influenced primarily by freeze–thaw cycles. Concentrations of most substances are increased by freezing–out during the winter. Because the lake does not circulate during maximum sprin...
