Arctic Mapping Program

On board the CCGS Amundsen

The Ocean Mapping Group’s role since 2003 has been to test the Amundsen’s acoustic equipment and collect as much depth, backscatter and sub-bottom data as possible throughout the Canadian Arctic. The primary purpose being to build up coverage with each transit through the passage. Data collected from the lengthy transits and planned surveys will allow scientists, hydrographers and the general community to better understand the Arctic seabed morphology and improve navigational safety.  Each year, collected data is processed and made available on-line to all interested parties, whether involved with the ArcticNet project or not, in numerous formats.

Why is the OMG in the Canadian Arctic?

“Project 1.6 (NW Passage) will map the bottom topography and geological structure of the NW Passage and other regions of the Canadian Archipelago as a first step towards the management of increased intercontinental ship traffic and resource exploration as ice conditions improve (Sea-Ice). Project 1.6 will contribute invaluable information to assess the economic, sovereignty and security implications of an icefree NW Passage (Theme 4).”
