British Geological Survey (BGS) Geophysical Survey 1979/15: Bosies Bank (15/08/1979 to 03/09/1979)
Report: Armstrong, EJ. 1979. Cruise Report for Project 79/14, West Shetland and Project 79/15, Bosies Bank. (IGS Report No 101). The aim of Project 79/15 was completion of regional geophysical coverage of the Bosies Bank sheet, of the IGS 1:250000 map series, on a grid ot NS-EW lines at approximately 10km by 10km spacing. Early in leg 1 the deep tow boomer failed and was out of operation for two days. The sparker results obtained were of good quality, as were those from the deep tow boomer when it was redeployed. The deep tow boomer, 1kJ sparker, transit sonar and watergun were run on all lines in leg 2, until maintenance on the watergun necessitated replacing it with a 40 cu.in. airgun. Both the airgun and watergun achieved up to 0.7s penetration. Pinger results were generally inferior to the boomer except in good weather and so were not used on all lines.
