Canadian Marine Multibeam Bathymetric Images

Digital multibeam bathymetric sounding is the premier reconnaissance marine mapping tool used by the Geological Survey of Canada. As the first stage of multiparameter geophysical surveys, multibeam bathymetry and backscatter intensity data are collected to image seafloor morphology and surficial sediments. These data form the basis for the preliminary interpretation of geological processes and morphological features, and are used to plan subsequent surveys using higher resolution sidescan sonar and seismic reflection systems to better define features identified on the multibeam data.

The Geological Survey of Canada has compiled various datasets of high resolution marine multibeam bathymetric data, comprising survey data collected by Natural Resources Canada and other partners and has made over 140 colour-shaded relief bathymetry images of these datasets accessible via this application. Point data or individual bathymetric soundings are not available through this application.
