The purpose was to collect data as part of a regional mapping programme. Sea floor data were collected using Transit Sonar and Sidescan Sonar.  Sub-bottom seismic profiling data were collected using Surface Tow Boomer; Pinger and Sparker. These data are archived by BGS. Technical details of the survey are contained in BGS report WB/MG/69/4.",
