Objective(s): To understand coastal processes and predict the effects of changing climate on the Canadian Beaufort Sea coast.

Project Description: The Coastal Impacts project on the Beaufort Sea coast has two complementary objectives: 1. To improve our understanding of coastal processes; 2. To develop methods for prediction of coastal impacts of changing climate. Field work will be performed in the modern Mackenzie Delta, along the Tuktoyaktuk Peninsula coast, and at North Head if time permits. Collaborative field work in Ivvavik National Park along the Yukon coast is also planned, as is very limited aerial photography if resources permit. The field work will concentrate on revisiting sites which were investigated in the past several years to look for changes that can be related to changing environmental parameters such as storms, floods, etc. We will also be observing the recovery of eroded areas affected by the fall 1993 storm. Erosion will be measured at GSC monitoring sites (Tent, Ellice, and Taglu Islands, North Head, Tuktoyaktuk, Tibjak Point, and Toker Point) and nearshore bathymetric profiles will be acquired where possible. The depth of the thawed layer in the beach and shallow nearshore will be probed using a jet drill. The jet drill uses high pressure water from a fire pump to dig a small-diameter hole in the soil
