Objective(s): The project involves a study of the climate, vegetation, and lakes over the past several thousand years in the region of Victoria Island. The objective is to determine how vegetation and aquatic algae found in this region responded to climate changes in the past several thousand years. The research team will attempt to determine what occurred during this time period by analyzing lake sediment cores that will be collected. Lakes are continually accumulating sediment, which provides an ideal historical record of this indicator of climate change. By analyzing the pollen contained in these sediments, the research team will attempt to determine how vegetation has changed in the region over time. This study will provide important information about the sensitivity of arctic vegetation to climate change, which may useful in predicting the effects of future climate change.

Project Description: The research team will be transported to the base camp site by PCSP Twin Otter, where a small camp will be set up. The camp will consist of one sleeping tent per team member and one cooking tent. All non-burnable garbage will be packed out, and human waste buried at the camp sites. The research team plans to access 6-8 lakes within walking distance of the base camp. Lake sediment cores will be collected using a hand-powered corer. Water samples will also be collected at each lake. All samples will be returned to the laboratory for detailed analysis.
