This British Geological Survey (BGS) regional marine sampling survey took placein May 1976 in the North Sea on board the RRS John Murray. The purpose was to gather data which could be used to map the regional geology of the area and undertake geochemical analysis.Seabed samples and cores were collected using Shipek grab and cone dredge. A total of 1750 km of data were collected in a grid of survey tracks. Sea floor data were collected using a transit sonar. Subsurface data were gathered using a pinger. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report 76/10.
