199219911990 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...

1992 Summary:
This project continues to examine the history of plant communities in the Mackenzie River and Delta regions over the past 15,000 years. Using a hand auger, core samples of sediments are taken from lake bottoms and the sediments are analyzed for the presence of pollen and diatoms. Radiocarbon dating, a technique used to estimate age, will estimate when certain species were present in the past....

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...
