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....
