Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
Principal Investigator: Nicholson, Barbara
Licenced Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

International Cryosol Tour
Principal Investigator: Tarnocai, C.
Licenced Year(s): 1991
Summary: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....

Evolution of High-Latitude Floras
Principal Investigator: Basinger, James F.
Licenced Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: Begun in 1985, this project will continue the study of plant evolution in high latitudes and the exploration for fossils in rocks of the Eureka Sound Group of Axel Heiberg and Ellesmere Islands. This season the field work will expand to Strathcona Fiord area and to east central Axel Heiberg Island. This information is used in the interpretation of global climatic change and the evolution of temper...

Mechanisms Mediating Freezing Tolerance in Arctic Insects
Principal Investigator: Kukal, Olga
Licenced Year(s): 1992 1991
Summary: Arctic arthropod communities are extremely sensitive to changes in their physical environment and their composition reflects trace elements in the atmosphere or minor fluctuations in termperature. This project is part of a larger, long-term project involving a survey of arctic arthropods which will ultimately provide a monitoring system for global climatic changes and indicate levels of pollutants...

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....
