Joint services expedition to the Blue Mountains, Ellesmere Island
chercheur principal: Smith, Roger F.
Année(s) de permis: 1994
Résumé: The researchers will conduct a variety of research activities at the study site. Projects include surveys of insects and plants, monitoring glacier movements, collecting data about the area's rocks and soils, assessing changes in the area's climate and environment (using fossils of microscopic marine organisms, chironomids, as indicators), and investigating radio-wave propagation....

INSTAAR Geological Fieldwork 1992, Northwest Territories, Canada
chercheur principal: Kaufman, Darrell
Année(s) de permis: 1992
Résumé: Three field parties will continue investigations related to past glacial activity in the eastern arctic during the last deglaciation (12,000 - 8,000 years ago). They will also research the geologic record of environmental changes preserved in lake sediments....

Glacimarine Sedimentation in Canon Fiord, Ellesmere Island
chercheur principal: Gilbert, Robert
Année(s) de permis: 1993 1992 1991 1990 1988
Résumé: 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...

Paleolimnology and sedimentology of lakes on the unglaciated terrain of Fosheim Peninsula, Ellesmere Island
chercheur principal: Wolfe, Alexander P.
Année(s) de permis: 1992 1991 1990
Résumé: 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....

Holocene Paleolimnology of a High Arctic Lake, Truelove Lowland, Devon Island, N.W.T.
chercheur principal: Vandenbygaart, B.J.
Année(s) de permis: 1992
Résumé: The Researcher will continue a chronology of environmental change during the development of Immerk Lake....

Paleoenvironment of the Truelove Lowland Area, Devon Island, N.W.T.
chercheur principal: King, Roger H.
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: 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....

Late Quaternary Dynamics of the Labrador/Foxe Sectors of the Laurentide Ice Sheet and Ice Sheet/Ocean Interaction in the North Atlantic
chercheur principal: Miller, Gifford H.
Année(s) de permis: 1994 1993 1991 1990 1989 1987
Résumé: The Research teams will continue to gather information to understand past glacial activity and sea level change in the eastern Canadian Arctic. They will take core samples from selected lakes and will record environmental change preserved in the lake sediments....
