Abstract: Ocean Mapping Group binary format data generated from the 2013 multibeam sonar survey on the 2013 CCGS Amundsen ArcticNet Cruise. The data include high-resolution bathymetry, acoustic backscatter and watercolumn backscatter. This project undertakes the core seabed mapping component of the ArcticNet research program. Underway acoustic mapping of the seabed relief, sediment distribution and shallow subsurface sediments are the prime datasets used by researchers to understand the geological processes shaping the seafloor, to assess natural hazards and coastal habitats and to reconstruct the history of past climatic changes. These mapping results are applied to specific projects including : Marine geohazards to hydrocarbon development, Opening new shipping lanes and improving navigational charting, Past to present evolution of sea-ice regime.
