Abstract : The discovery of density stratification in Lake Tuborg, northern Ellesmere Island (lat. 80 deg 50 min N, long. 70 deg W), alerted us to the possibility that other lakes in the area might show the same phenomenon, provided they were near enough to sea level to allow the trapping of seawater either through advance of a glacier or through postglacial rise of land. Lake Tuborg is an example of a lake that has been cut off from a fiord (Greely Fiord) by glacier advance; the radiocarbon age of the old seawater near the bottom of the lake indicates that this occurred about 3,000 yr ago.
