In the frame of the Continental Margin Study Program of the Federal Institute for Geosciences and Natural Resources (BGR, Hannover) marine geophysical measurements (48-channel reflection seismic, sono-buoy refraction, gravity and magnetic) were conducted over the Atlantic continental margin of Canada from 23th July to 7th August 1979 with S.V. EXPLORA (BGR79 leg 2). The survey on the Canadian continental margin was planned in cooperation between the Federal Institute for Geosciences and Natural Resources (BGR) and the Atlantic Geoscience Centre of the Geological Survey of Canada (Bedford Institute of Oceanography, Dartmonth, N.S.) on the base of existing Canadian multichannel seismic lines. A main target of the cruise was to acquire data which allow a comparison of the deep sedimentary basins offshore Nova Scotia with the already known basins offshore Morocco. The eastern part of the survey imaged complex structural deformation due to salt diapirs. The western seismic lines allowed to investigate the structural relationship between the Scotian Basin and the Georges Bank.
