Principal Investigator: Bogen, Jim J
Licensed Year(s): 2010
Summary: The objective of this research is to estimate the modern and historical fluxes of sediment- associated chemical elements to the Arctic Ocean and their relationships to natural and man-induced changes in sediment yields and sediment sources and if possible, predict the impact of future climate changes on the fluxes. The study will include sampling of overbank sediments from floodplains and del...

Principal Investigator: Long, Darrel G.F.
Licensed Year(s): 1997
Summary: During the summer of 1997, the researchers will visit several cliff exposures of sandstone in the Mackenzie Mountains in the Carcajou Canyon (NTS 96D) and Wrigley Lake (NTS 95M) map areas, south of Norman Wells and west of Tulita, in order to obtain information on the shape of structures preserved in sandstones deposited by ancient rivers. By determining the geometry of these sandstone bodies it ...

Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1993 1992 1991 1990
Summary: The researcher will continue her long-term study on the physical features of the Mackenzie Delta. Hydrocarbon development, water volume and course changes, and climate change could have major effects on the water and sedimentation patterns of the delta. This study will increase knowledge of sedimentation patterns, shoreline erosion and their relationships with vegetation....

Principal Investigator: Retelle, Michael J.
Licensed Year(s): 1992 1991 1990
Summary: The researchers will attempt to reconstruct climate and past environmental conditions through recovery and study of sediment cores from lakes at Taconite Inlet, northern Ellesmere Island. They will also monitor conditions under which the lake sediments are presently accumulating....

Principal Investigator: Lewkowicz, Antoni G
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: The overall aim of this research is to establish links between climate and the activity of geomorphic processes so that predictions can be made about the possible impact of any climate change. This project will help to understand how the climate affects the processes that move soil down slopes into rivers and eventually to the sea....

Principal Investigator: Dyke, Larry
Licensed Year(s): 1992 1991 1990
Summary: The research will involve permafrost adjustment studies on the outer Delta as well as preliminary work on landslide mechanisms along the Mackenzie River between Norman Wells and the head of the Mackenzie Delta. The purpose of the work is to understand the importance of sedimentary processes in controlling the growth and disappearance of permafrost along the coast of the Beaufort Sea....

Principal Investigator: Gilbert, Robert
Licensed Year(s): 1993 1992 1991 1990 1988
Summary: The Researcher will use a special type of echo sounder to determine the depth of the water and the thickness of the sediments beneath down to bedrock. The instrument also shows the patterms of sediment distribution around the fiord. From this, an assessment can be made of where the sediment has come from, how much there is and how the patterns of sedimentation have changed during the entire perio...

Principal Investigator: Dallimore, Scott R
Licensed Year(s): 1994 1993 1993 1992 1992 1991
Summary: A transect consisting of geotechnical boreholes and detailed geophysical studies will document the geological, geothermal and geotechnical conditions of perennially frozen sediments at three sites on Richards Island in the Mackenzie Delta....

Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher will continue to investigate lakes on the unglaciated terrain of Fosheim Peninsula to determine the former environments of high and low arctic lakes. By analyzing the physical and chemical properties of the sediments, as well as the preserved biological remains within them, the nature and timing of rapid environmental changes at the close of the last glaciation may be explained....

Principal Investigator: King, Roger H.
Licensed Year(s): 1994 1992 1991 1990 1988
Summary: Dr. King and his team will continue their study of the record of past environmental changes preserved in the sediments of the Truelove Lowland. Once again the focus of their field work will be the sediments that have accumulated in the larger, deeper lakes and the soils in the areas surrounding these lakes....
