British Geological Survey (BGS) Geophysical Survey 1970/3: Moray Firth and East and south of Orkney (23/05/1970 to 17/06/1970)

Report: Sunderland, J, and Tully, M. 1970. Cruise Report for MV Surveyor. MGU Project 70/03. (IGS Report No 9) Positioning: Main Chain Decca using Decca Type 1844 Type receiver. Coastline corrections were applied to reduce fixed errors when within 0.5 Nm of the coast. Echo Sounding: Kelvin Hughes MS 32 Sonar Systems: EG&G side-scan sonar. Kelvin Hughes Transit sonar also used. Seismic Systems: Sparker System: EG&G sparker system with 263b hydrophone streamer. Most lines run at 1kJ Gravitymeter: LaCoste and Romberg Air Sea gravity meter. Magnetometer: RVU Barringer magnetometer

报告：Sunderland, J，与Tully, M. 1970年。MV Surveyor巡航报告。MGU项目70/03。（IGS报告编号9）定位：采用Decca Type 1844型号接收机的Decca主链进行定位。在距离海岸0.5海里以内，应用海岸线校正以减少固定误差。回声测深：Kelvin Hughes MS 32声纳系统：EG&G侧扫声纳。同时使用Kelvin Hughes越洋声纳。地震系统：震源系统：EG&G震源系统，配备263b水听器流束。大部分测线以1kJ的功率进行测量。重力仪：LaCoste和Romberg空气海洋重力仪。磁力仪：RVU Barringer磁力仪。
