The data set is an image of colour-shaded sun-illuminated seafloor topography collected in teh nearshore region of the Mackenzie Delta in the Beaufort Sea in 2007 by the Geological Survey of Canada (Atlantic) (GSCA). Data were collected with a SwathPlus Interferometric Sidescan system on Geological Survey of Canada (Atlantic), Multibeam Expedition, Beaufort Explorer 2007306. Depth readings are accurate to within 30 cm in water depths less than 30 m and 1% of water depth in water depths greater than 30 m. These data were collected using Differential Global Positioning System (DGPS) which determines the position of the vessel with an accuracy of 3 to 5 m. The horizontal accuracy of the swath data is variable, depending on beam angle, water depth and inaccuracies due to sound velocity profile errors.
To create the colour-shaded relief a depth color gradient is applied to a grey-scale image. To have more information about this process and the other image, please refer to the data file entitled: Strudel_Scours_2007_Mackenzie_Delta_Seafloor_Extended_Metadata_FGDC_csr.xml or Strudel_Scours_2009_Mackenzie_Delta_Seafloor_Extended_Metadata_FGDC_csr.xml
Purpose: To aid in the development of interpretive geologic, geohazard and seabed characterization products.
