5200 |a"The Polaris lead-zinc mine at latitude 75N is the world's most northerly mine. This mine discharges its tailings into Garrow Lake on Little Cornwallis Island. High concentrations of heavy metal sulfides accumulate in the stable bottom layer of the lake, although they appear to pose no problems for the life in the upper layer of the lake. Garrow Lake, and Sopha Lake on an adjoining island are interesting examples of two meromicic lakes, which we believe have developed their strong salinity gradients through differential freezing each year"--Management perspective.
