Surficial geology and shaded seafloor relief, Georges Bank, Fundian Channel, and Northeast Channel, Gulf of Maine. : M183-2/7657E-PDF

"This map shows the surficial geology of a portion of the Canadian segment of Georges Bank at a scale of 1:50 000. Surficial sediment type is coded by colour on the map. This surficial geology map has a companion map of shaded-relief seafloor topography and backscatter strength imagery that shows the relative reflectivity of the seafloor substrates in response to sound waves. The maps are based on multibeam-echosounder surveys conducted in 1999 and 2000 to map 11,965 km² of the seafloor. … On this map of surficial geology, water-depth contours generated from the multibeam-echosounder data are shown (in white) on the colour-coded surficial geology image at a depth interval of 10 m. Bathymetric contours (in blue) outside the multibeam survey area, presented at a depth interval of 25 metres, are from the Natural Resource Map series …"--Introduction.
