Mesoscale Climates and Paleoclimates of the Baffin Island Region
Principal Investigator: Jacobs, John D.
Licenced Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: The Research team will study climate using information from permanent weather stations. They will continue to set up and monitor automatic weater stations. Local environments of the interior of Baffin Island will be investigated to see how the climate and vegetation have responded during times of great change in the earth's climate, such as the end of the last ice age and the warmer period that fo...


1. Permafrost and Ground Ice of the Expedition Fiord Area; 2. An investigation of the Origin and Nature of Massive Ground Ice on the Fosheim Peninsula
Principal Investigator: Pollard, W.H.
Licenced Year(s): 1994 1992 1991 1990 1988
Summary: This research involves the field investigation of natural exposures of massive ground ice and bodies of surface ice. Sites identified in previous field seasons will be visited and samples of ice, water and sediment will be taken for further analyses. The results of this research will help in the interpretation of climate change and the assessment of both natural and human induced terrain disturban...


An Evaluation of SPOT Data to Map Ground Cover in the Canadian High Arctic
Principal Investigator: Jetty, Tammy
Licenced Year(s): 1991
Summary: The Researcher will carry out fieldwork in association with Dr. Cheryl M. Pearce. The study will investigate if the the response of arctic surfaces to climate changes can be detected, monitored and mapped using space imagery....


An Evaluation of Satellite Data to Detect and Monitor Vegetation Responses to Climate Warming at Treeline
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1993 1992 1991 1990
Summary: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...


Holocene Bowhead Whale (Balaena mysticetus) Skeletal Morphometrics and Taphonomy in the Eastern Canadian Arctic
Principal Investigator: Savelle, James M.
Licenced Year(s): 1992 1990
Summary: The Researcher will record and measure whale bones from naturally stranded bowhead whales. The information will be used to assist in determining the effects of climatic change on bowhead whale populations over the last 10,500 years....


Paleontology and Stratigraphy of the Ordovician - Silurian Boundary on Northeastern Cornwallis Island, N.W.T.
Principal Investigator: Melchin, Michael J.
Licenced 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....


Influence of Stream Discharge on the Distribution of Sea Ice with Climatic Implications
Principal Investigator: Dean, Ken
Licenced Year(s): 1991 1990
Summary: Satellite imagery, hydrologic data and field measurements will be used to develop a computer model of the thawing of sea ice and freezing of water in this area. The investigators will drill a hole through the ice and measure water temperature, salinity and turbidity....


Extensive Dendrochronological Reconstruction of Temperature in the Northern Hemisphere: North American Boreal Zone
Principal Investigator: Jacoby, Gordon C.
Licenced Year(s): 1994 1989
Summary: The object of this research is to reconstruct past climate in order to understand how the climate system works, and what past natural variations may be expected based upon this information. This project is to sample old-aged trees and to assemble enough coverage to reconstruct regional and Hemispheric temperatures for the most recent centuries....


The Influence of Thermokarst Subsidence on Peatland and the Role of Climatic Change within the Discontinuous Permafrost Zone in the Southern Mackenzie Valley
Principal Investigator: Spivey, Diane
Licenced Year(s): 1988
Summary: Diane Spivey is interested in knowing why there is less permafrost now in peatbogs. First, she will be mapping areas that have thawed and collapsed. Then, she will be looking and sampling vegetation to see if the vegetation has been disturbed so that it no longer insulates the permafrost as well. Last, she will look to see how well peat retains heat and acts as an insulator. She will use this i...


Licence #5070
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 1985
Summary: To collect surface samples from small lakes to reconstruct the response of plant populations in the treeline zone to climatic change....
