    This British Geological Survey (BGS) geophysical and sampling survey took place in May 1974 in the South Forties area using the MV Whitethorn. The main purpose was to compare methods of geophysical profiling and geotechnical testing. Sea-bed samples and cores at fifty seven stations were collected using Gravity corer, Vibrocorer and shipek grab/camera. Geophysical lines run included Pinger, sparker, boomer and echosounder equipment. Position fixing during the cruise was Decca Main Chain. These data are archived by BGS. Technical details of the survey are contained in BGS Technical Reports WB/MI/74/10.

    This high resolution marine multi-channel seismic survey commissioned by the Institute of Geological Sciences on behalf of Department of Energy took place in the Northern North Sea during 1st-27th November 1979 (Phase 1) aboard MV Aqua Star and 1st-14th February 1980 (Phase2) aboard Gardline Tracker. Phase 1 (Lines 1-5) was carried out by Fairfield Auatronics Ltd and Phase 2 (lines 5B-9) by Gardline surveys Ltd. Line coverage total 445km (Phase1 - 180km; Phase 2 - 265km). Sea floor data were collected using Echo sounder. Subsurface seismic data were gathered using a 9/15KJ sparker and line 4, Fairflex sleeve exploder. Survey details are contained in Fairfield and gardline acquisition reports and BGS technical report WB/MG/81/124.
