Summary: This long-term, ongoing study is aimed at understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta. This work will allow us to better understand the natural Mackenzie Delta ecosystem, and to make better predictions of the effect of environmental change on the Delta. Cores of sediment will be collected from lake bottoms to d...

Summary: The Canadian Beaufort Sea coast undergoes rapid changes in formation, including the formation and changes of spits and barrier islands. Climatic change, combined with a rise in sea levels, could result in longer ice-free periods, increased wave action and higher rates of coastal retreat and erosion. By measuring spits and barrier islands, analyzing the make-up of the coastal sediments, and measu...

Principal Investigator: Fassnacht, Steven
Licensed Year(s): 1992
Summary: At both the East Channel (Mackenzie Delta) and at Cabin Creek the elevation at various cross-sections will be measured so that a detailed contour map may be plotted. River bed material will be sampled to determine the size distribution of the bed material....

Principal Investigator: Vincent, Jean-Serge
Licensed Year(s): 1992 1991 1990
Summary: The researcher and his team will complete a detailed paleomagnetic sampling of the glacial and nonglacial sediments in the Morgan Bluffs of eastern Banks Island, and collect samples of boulders for Chlorine 36 dating. The data will allow the team to confirm or disconfirm previously proposed correlations and establish on a firmer basis the chronological framework for one of the longest sequences o...

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: Hill, Philip R.
Licensed Year(s): 1994 1993 1992
Summary: The purpose of this project is to understand how the Mackenzie Delta and adjacent coastal regions have developed over the last 18,000 years, since the last glaciation affected the region. The project will includes investigating the sub-surface development of the delta and studying the processes by which sediment supplied by the river is transported to the continental shelf and coastal waters....

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: Dyke, Larry
Licensed Year(s): 1988
Summary: To place temperature probes using a water jet to measure temperatures beneath a 2 km long spit at the north end of Richards Island to determine if the accumulation of these sediments has influenced the distribution of permafrost....

Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1987
Summary: To analyze the environmental processes that control plant distribution and succession on shorelines of the Mackenzie Delta. Specific objectives of the research are to examine (1) the colonization and establishment on exposed mudflats and other newly-available sites, (2) the responses of the shoreline plants to fluctuations in the biophysical environment, and (3) the chemical and physical properti...

Principal Investigator: Rainbird, Robert H
Licensed Year(s): 1987
Summary: To carry out stratigraphic section measurement, geological mapping and sampling of rocks for laboratory analysis....
