An index has been compiled of more than 200 surficial geology surveys that have been conducted on the Scotian Shelf. The co-ordinates for about 7,000 sample stations and 70,000 line kilometres of shallow seismic profiles have been plotted on four separate basemaps for the Scotian Shelf. Sources for the compilation include the Government of Canada, the oil and gas industry, various universities, and foreign agencies. Only 36 of the surveys are not in the public domain.
