Permafrost response to recent climate warming in the Mackenzie Delta and Yukon Coast.
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...


Hydrologic investigation of a Canadian Shield basin
Principal Investigator: Spence, Chris
Licensed Year(s): 2001 1999 1998
Summary: Lower Carp Lake is part of the Yellowknife River and is roughly 22km in size. A number of remote meteorological and hydrometric data collection sites will be constructed around the lake. An island on the lake will be used as a base camp for the research activities. This island is roughly circular rising up to 50m from the lakeshore. A portion of the island is dominated by sandy glacial deposits. M...


MAGS Ground-Based Measurement Studies
Principal Investigator: Kochtubajda, Bob
Licensed Year(s): 1998
Summary: We propose to transport ad install new automatic weather stations by truck, fixed wing and helicopter to three sites in the Fort Simpson area between mid-June through mid July 1998. The automatic weather stations are both solar-powered and battery-powered, and collect and transmit meteorological data for use in weather forecasts and warnings. The weather stations will be used to support the scien...


Organic Carbon Accumulation in discontinuously frozen peatlands
Principal Investigator: Robinson, Stephen
Licensed Year(s): 1996 1995
Summary: Research will be conducted in a peatland complex approximately 12 km west of Fort Simpson (4 km west of the Wrigley Road). The major component of the field work will include the collection of peat cores in both frozen and unfrozen terrain to about 1 m depth. A total of approximately 100 cores will be collected. Core holes will be approximately 15 cm wide, and will be filled to minimize terrain ...


Investigation of ground ice development in sediments of the Mackenzie delta area.
Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
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....


Permafrost Studies: Western Arctic Coast
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....


Coastal Impacts of Climate Change
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...


Impact of Climatic Change on Earth Surface Processes, Fosheim Peninsula, Ellesmere Island
Principal Investigator: Lewkowicz, Antoni G
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: The aim of this ongoing research is to establish links between climate and the movements of soil. By collecting this type of data, it may be possible to determine the effect that climate changes may have on the movements of soil down slopes, into rivers and eventually into the sea. The project has been underway for several years because soil movements are mostly slow and therefore difficult to mea...


Hydrology and geochemistry of a high arctic lake basin: Colour Lake, Axel Heiberg Island, NWT
Principal Investigator: English, Michael C
Licensed Year(s): 1994 1992 1991
Summary: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the...


Mackenzie Valley Global Change Observatory
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....
