An Evaluation of Data Collected by Orgiting Satellites to Detect and Monitor Arctic Surfaces
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1993 1992 1991 1990
Summary: The Researcher will examine what distinguishes arctic surfaces spatially and spectrally and which surfaces can be detected and identified by sensors on orbiting satellites, and will test the hypothesis that orbiting satellites can be used to detect and monitor thaw slumps, coastal erosion and other physical and biological manifestations of environmental change in the arctic....

Spatial and Temporal Variation of Vegetation on Raised Beaches, Devon Island
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1988 1987
Summary: Dr. Pearce and her associate are returning to Truelove Lowland to evaluate an idea that plant associations growing on raised beaches of different ages are a result of the type of soil and water conditions they are growing on rather than the amount of time that they have had to live there....

The relationships between modern pollen sedimentation and present vegetation distribution on Truelove Lowland, Devon Island.
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1987
Summary: To 1) collect and analyze present-day pollen sedimentation from major plant communities on several high arctic site types, 2) to correlate this production with actual plant cover, and 3) to compare the modern pollen rain to historical pollen deposits analyzed in the Department of Geography, University of Western Ontario (R. King) and during the I.B.P. Project (Jankovska and Bliss)....
