| abstract |
This marine geophysical survey was carried out by Institute of Geological Sciences now British Geological Survey (BGS), the survey took place in July 1967 off St Abbs on board the MV Braw Lads. The purpose was to ascertain whether or not it is possible with limited techniques to trace a connection between the Dunbar and Tweed Carboniferous basins a short distance offshore. Sea floor data were collected using echosounder and transit sonar. These data are archived by BGS. Technical details of the survey are contained in IGS report 70/1.
