Project Description: The objective of the seabed mapping program is to conduct a regional survey of the Beaufort Shelf over the next four years. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, sub-sea permafrost and coastal stability will be investigated.

The Coast Guard vessel CCGS Nahidik will be used to collect seabed sediment samples and bottom photographs and to conduct offshore acoustic/sonar surveys of the seabed.

This year, the research team will: map the topography and character of the seabed; map the distribution and depths of ice scours; map the distribution of sediments to 100m below the seabed; photograph the nature of the seabed; collect 80-100 seabed sediment samples; and, collect bathymetry data in the nearshore water off the Mackenzie Delta front and in the vicinity of Tuktoyaktuk. .

Four northern community students will be employed during the survey. The students will each spend 7 to 10 days onboard CCGS Nahidik. Students will be assigned projects related to their interest to be submitted to their home community or classroom after the field program.
The study will be conducted at the Canadian Beaufort Continental Shelf, in a survey area bounded by: 131ºW to 141ºW and 69º30'N to 71ºN. Exact locations to be surveyed on the shelf are dependent on weather and sea-ice conditions. The CCGS Nahidik will be mobilized out of Inuvik and demobilized out of Tuktoyaktuk and Inuvik. The research will be conducted from July 25 to September 27, 2005.
