Summary: A special type of echo sounder will be used to determine the depth of the water and the thickness of the sediments beneath down to bedrock. The instrument also shows the patterns of sediment distribution around the fiord. From these results, 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 period...

Principal Investigator: Washburn, A.L.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: Dr. Washburn and his assistant will continue the investigation into how the landscape has changed since the glaciers left 10,000 years ago. In particular, he is looking at how the effects of frost and permafrost have influenced the changes....

Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: During the last glacial period, 110,000 to 5,000 years to present some lakes escaped glaciation. The Researcher will retrieve sediment cores from three upland lakes to investigate the physical responses of the sediments and the biological responses of algae toward this climatic event....

Principal Investigator: Black, Thomas A.
Licensed Year(s): 1990
Summary: The Researcher and his assistant will paddle a route from Coppermine up the Rae River across the watershed and down the Hornaday River. They will examine the fluvial geomorphology and evidence of continetal glaciation along this route....

Principal Investigator: Melchin, Michael J.
Licensed Year(s): 1992 1991 1990 1988
Summary: The Researcher and his assistants will carry out fieldwork which involves the collection of fossils (most of which are microscopic), rock samples, photographs and notes on the outcrops on northeastern Cornwallis Island. The work is to lead to a better understanding of the environmental changes brought about by changing climate....

Principal Investigator: Lemmen, S. Donald
Licensed Year(s): 1987
Summary: To define the extent of ice coverage on Marvin Peninsula during the last glaciation, and the nature and extent of glacial features which predate the last glaciation. To recover sediment samples from Disraeli Fiord in order to define contemporary glaciomarine litho and biofacies. To study postglacial emergence to clarify the nature of relative sea-level changes in the region....

Principal Investigator: Semmel, Arno
Licensed Year(s): 1985
Summary: To obtain more information about periglacial process and environments in a formerly unglaciated area with regard to slope denundation and fluvial process. To show the differences between areas of continuous and discontinuous permafrost. To investigate along the Dempster Highway different valley-profiles by mapping the geomorphological features and to take soil samples....

Principal Investigator: Schunke, Ekkehard
Licensed Year(s): 1981
Summary: To conduct a study of land forms, valley formations and slopes relating to the periglacial environment....

Principal Investigator: Morgan, Alan
Licensed Year(s): 1980
Summary: To make collections of various types of insects, principally beetles (Coleoptera) and caddis flies (Trichoptera). The primary purpose of the exercise is to expand the reference collection of insects at Waterloo. Secondary to the exercise is a determination of the effect of recent glacial periods on these insects....

Principal Investigator: Miller, Gifford H.
Licensed Year(s): 1977
Summary: To study raised marine and glacial deposits - by the collection of marine fossils for dating the history of glaciation....
