Colour-shaded seafloor relief, Southeast Garry Island 2009, Mackenzie Delta, Beaufort Sea, offshore northern Canada
The data set is an image of colour-shaded sun-illuminated seafloor topography collected near Garry Island in the Mackenzie Delta in the Beaufort Sea in 2009 by the Geological Survey of Canada (Atlantic) (GSCA). Data were collected with a SwathPlus Interferometric Sidescan system on Geological Survey...
