Project Description: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness.

Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the researchers will determine: active-layer depths; soil characteristics, from previously obtained soil core samples to a depth of 2m; terrain; and, vegetation. They will make measurements at the sites by surveying and with temperature probes. The research team will travel to the research sites by boat, aircraft, or on foot. Fly camps will be established at each of the respective sites for a period of two to three days.

The research team will take a local person in the field and keep people in Inuvik informed of their activities through the Aurora Research Institute. The researchers will prepare a poster for the HTCs in the area and give a copy to the Aurora Research Institute and Parks Canada. They are also available to give talks about their work to interested community members.

The study will be conducted at the Mackenzie Delta, in the Caribou Hills, from July 16 to August 26, 2005.
