This British Geological Survey (BGS) regional marine geophysical and sampling survey took place from April to May 1972 in Firth of Clyde and Sea of the Hebrides on board the MV Whitethorn. Sea floor data were collected using an echosounder. Subsurface data were gathered using pinger and sparker equipment, a total of 460km were covered. Seabed samples and borehole cores were collected using a Hydrocorer and wireline drilling. Five borehole sites drilled. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report WB/72/3.

This British Geological Survey (BGS) marine sampling trials survey took place in January 2013 in the area of Loch Linnhe on board the Northern Lighthouse Board vessel NLV Pharos. The aim was to test the BGS seabed rockdrill RD2.

This marine multibeam survey took place in May 2008 in Liverpool & Tremadog Bays on board the RV Prince Madog. The survey was carried out by the British Geological Survey (BGS) and Proudman Oceanographic Laboratory (POL). These data are archived by BGS.

This British Geological Survey (BGS) sampling survey took place in January 1987 to the West of the Shetland Islands on board the Kommandor Subsea. Seabed cores were collected using Vibrocorer and Gravity corer. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report WB/87/7.

This British Geological Survey (BGS) regional marine geophysical and sampling survey took place May to June 1972 in Moray Firth, off Aberdeenshire and Forth Approaches on board the MV Whitethorn. Sea floor data were collected using an echo sounder and transit sonar. Subsurface data were gathered using pinger and sparker equipment, a total of 531km were covered. Seabed samples and cores were collected using a shipek grab, gravity corer, vibrocorer, shell and auger and wireline drilling equipment. 9 borehole sites were occupied. Additional geophysical records (Line 61) were collected for Survey 72/W3 by MGU onboard ‘MV Researcher’ Survey 1972/4. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report WB/72/7.

Report: Deegan, S.E. 1975. Cruise report for Pockmarks study in the Forties area, 3-16 July 1975. Marine Geology report 75/13, MGU Project 75/07. MGU reports 60, 64 & 98 & UC97.

This marine multi-channel geophysical survey commissioned by the British Geological Survey (BGS), acquired and processed by Seismograph Service (England) Ltd took place 12th August to 2nd September and 21st September to 14th October 1969 West of Scotland aboard m.v. Ole Wirum. The main objective was to reveal the structure of the Mesozoic basins, information was incidentally acquired on tertiary dykes and Lave flows and on a submarine plutonic centre. Sub surface data were gathered using gas exploders, 1033km were covered by 17 lines. These data are archived by BGS. Technical details of the survey are contained in an Acquisition Report. Summary details contained in IGS report 74/12.

This British Geological Survey (BGS) regional marine sampling survey took place in May/June 1984, North of Scotland on board the drillship Ferder. Seabed borehole cores were collected using wireline coring system. These data are archived by BGS. Technical details of the survey are contained in BGS Marine Geology Report 84/9.

This manned submersible sampling survey undertaken by the British Geological Survey (BGS) took place in June 1970 in the Sea of The Hebrides areas aboard the vessel Vickers Venturer. The purpose was to evaluate the institutes shallow seismic and allow close examination of the representative geomorphological features and sedimentary environments and the transitions which take place between them, sample rock outcrops and evaluate the use of a sumbrsible for this type of work. The manned submersible operated by a pilot and geologist observer was fitted with two stereo cameras, rockdrill and manipulator arm. Twenty dives were undertaken to obtain geological samples. These data are archived by BGS. The geological results and investigation techniques are contained in BGS (IGS) report 71/16.
