Objective(s): To determine the long-term (i.e., thousands of years) vegetation history of the central Arctic Islands by collecting sediment cores from the bottoms of several lakes on northern Prince of Wales Island and southern Bathurst Island and analyzing sediment and pollen characteristics of these cores. In addition, modern pollen deposition will be studied on the Fosheim Peninsula, Ellesmere Island, to determine the `signature' of present day vegetation in lake sediment.

Project Description: 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. Present day pollen will be collected on Ellesmere Island.
