Northern River Ice Regimes
Principal Investigator: Sherstone, David A.
Licensed Year(s): 1993 1992 1991 1990 1988
Summary: Simple, inexpensive ice thickness gauges are installed on river channel ice. Usually 3-4 gauges per channel. Twenty gauges are installed in the Mackenzie Delta and 12 in Hay River. Every 10 days the gauges are read to obtain the total ice,white ice and snow quantities at each site. From this data the rates of ice growth and decay can be calculated and the approximate date at which the ice will...
