This British Geological Survey (BGS) marine geophysical and sampling survey took place in September/October 1976 in the Irish Sea and St. George's Channel on board the RRS John Murray. The purpose was to gather data which could be used to map the regional geology of the area. Cruise was virtually aborted by bad wather. Sediment cores were collected using a rock gravity corer. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report ??????????????.
