Summary: Soil samples will be taken from two to three potential sump sites for the 2005 drilling program. Soil samples will provide information on active layer depth, soil composite, salinity levels, permeability and moisture content to determine sump site suitab...

Summary: The proposed research will investigate the physical and chemical characteristics of the near-surface ice-rich zone in sediments of the Mackenzie Delta area. The goals of the research are to investigate the relationship between ice-rich permafrost and fo...

Summary: Changes in the ground due to uplift, associated with the growth of a pingo, and sideways movements due to the growth of ice wedges, will be measured. Air, ground, and lake water temperatures will be measured, in order to find out how the ground is responding to climatic variation. The reseach team will also return to Paulatuk, to continue studies Dr. Mackay began there 50 years ago. Travel to s...

Principal Investigator: Lacelle, Denis
Licensed Year(s): 2000
Summary: This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...

Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 1999
Summary: The objective of the present study is to assess the impact of recent warming, including the warm summer of 1998, on active layer thicknesses and slope stability in the Mackenzie Delta, N.W.T. and Yukon North Slope. The main mode of transportation will be by helicopter (206L) and by boat to transport people. The helicopter will be based out of Inuvik with a fuel cache at Tuktoyaktuk. The helicop...

Summary: The purpose is to collect samples of ground ice and to measure air, ground, and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousands years, in order to determine what might happen in the future....

Principal Investigator: Mackay, J. Ross
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991 1989
Summary: The researcher will continue studies on the origin of permafrost, the ice found within permafrost and processes that help to create the present geocryologic environment. These studies will be conducted on Garry Island, Illisarvik, 20 km southwest of Tuktoyaktuk and at Paulatuk....

Principal Investigator: Solomon, Steven M
Licensed Year(s): 2000 1999 1997 1996 1995 1994 1993 1992
Summary: The researchers will revisit sites which were investigated in the past several years to look for changes which can be related to changing environmental parameters like, storms, floods, etc. They will also be observing the recovery of eroded areas which were effected by the fall, 1993 storm. Erosion will be measured and bathymetric profiles completed. The depth of the active layer in the beach a...

Principal Investigator: Egginton, Paul A.
Licensed Year(s): 1992 1990
Summary: The team will install active layer monitoring stations at up to 8 sites on Richards Island. They will sample present active layer and surface permafrost for analysis of recent change as well as lake bottoms for similar reasons and a possible sea level record....
