Ice Thickness Topography Study -Beaufort Sea
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The researchers will retrieve untended sonar instruments operating beneath the sea that were positioned in April 1994. After servicing, these instruments will be re-deployed at the same locations to continue the observations for another year. A survey of water water properties will be collected at about 20 sites in the offshore and observations made using a lowered probe to 1500 m depth or to t...

Permafrost Studies: Western Arctic Coast
Principal Investigator: Mackay, J.R.
Licenced Year(s): 1997 1996 1995 1994 1993 1992 1991 1989
Summary: This on-going research of permafrost growth involves investigations at a large lake artificially drained in 1978. The study of pingos, started in 1969, and the study of ice wedges, started in 1966, involve measurements of ice growth....

Northern River Ice Regimes
Principal Investigator: Sherstone, David A.
Licenced 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 in the Mackenzie Delta and 15 gauges on Hay River). The 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 also be determined....

Licence #5033
Principal Investigator: Jeffries, Martin O.
Licenced Year(s): 1985
Summary: To obtain ice cores from the sea ice and to examine the salinity and isotopic compostition of the ice in addition to the ice temperature to determine ice strength, age of the ice and rates of growth....
