Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

Principal Investigator: French, Hugh
Licensed Year(s): 1997
Summary: The researcher will be studying the cryostructures which occur in perennially frozen, unconsolidated ice rich sediments. This builds upon earlier work in the Sachs Harbour and Sachs River Lowlands undertaken in the period 1970-1985. Will use boat transportation across the Sachs Harbour Bay and possibly towards Cape Kellett. The 1997 work will be a reconnaissance visit. This work will be continue...

Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: This on-going research will continue to examine the nature of frost heaving, permafrost and water flow in the Mackenzie Delta and associated lakes. Some experimentation on frost heaving will be conducted at specific sites during the winter months. In the summer, the distribution of ice in the upper layers of the permafrost on land as well as the nature of permafrost beneath shallow lakes will be...

Principal Investigator: Mackay, J.R.
Licensed 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....
