Summary: The researchers plan to measure weather conditions in the Sophia Lake area, together with measurements of stream flow and sediment movement in the lake. This information will help us to understand what controls the transfer of sediments from the land to the lake, and how this transfer is dependent on year-to-year changes in the weather. By examining the lake sediments, we may be able to reconstr...

Summary: Researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Hay River, the Slave River delta and the channel region east of the Slave River. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect small animals (invertebrates) which are eaten by fish as part of an over...

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....

Summary: This ongoing project examines how vegetation has changed in response to changes in climate. I am using the history of vegetation, as recorded by the fossilized pollen that is present in lake sediments, to determine how vegetation in the arctic has changed over thousands of years. Fossilized pollen is collected by taking core samples from lake bottoms on Prince of Wales and Bathurst Islands. Pre...

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: Hequette, Arnaud
Licensed Year(s): 1993 1992 1991
Summary: The researcher and his team will survey beach profiles using an electronic level, survey shallow lagoons and nearshore zones, collect nearshore sediment samples and deploy current meters in the nearshore zone and in a shallow lagoon....

Principal Investigator: Hiscott, Richard
Licensed Year(s): 1991
Summary: The Researchers will: map the geometry of debris-flow (mudflow) deposits; document bottom slopes and flow paths; relate debris-flow activity to Pleistocene history of the area and sea-bed cores and use this data to quantify the subaqueous (below water) debris-flow process....
