Northern River Ice Regimes
Principal Investigator: Sherstone, David A.
Licensed Year(s): 1993 1992 1991 1990 1988
Summary: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges for the Mackenzie Delta and 15 gauges for Hay River). These gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can be determined....
