British Geological Survey (BGS) Geophysical Survey 1979/14: Shetland (10/07/1979 to 14/08/1979)
Report: Armstrong, EJ. 1979. Cruise Report for Project 79/14, West Shetland and Project 79/15, Bosies Bank. (IGS Report No 101). Project 79/14 was designed to provide regional geophysical coverage of the Foula sheet, of the IGS 1:250000 map series, on a N-S, E-W grid of lines at approximately 15km by 9 km spacing. A number of gravity lines were also to be run over the Orkney sheet to complete gravity coverage in that area. In addition, some regional geophysical lines were to be surveyed on the Halibut Bank sheet after a study of the FLAGS pipeline route with the Huntec deep tow boomer. The watergun provided superior records to those of the airgun giving resolution comparable to the sparker in fair weather, down to 800ms of sediments. Up to 400ms penetration was achieved by the sparker, while the boomer provided good resolution in the shallow section. In depths less than 300m the transit sonar was used.
