abstract: This British Geological Survey (BGS) geophysical survey took place in September to October 1973 in the SW Approaches and Lizard area on board the TSS Profiler and formed part of the British Geological Survey (BGS) regional mapping project. The main purpose was to compare methods of geophysical profiling and geotechnical testing. Geophysical lines run included Edo Western Echo Sounder & Bridge Echo Sounder, 1000 J sparker, with Geomecanique hydrophone and Huntec recorder, Transit Sonar MS 47, gravimeter and magnetometer. Equipment. Position fixing during the cruise was Decca Main Chain or AMI satellite navigation. These data are archived by BGS. Technical details of the survey are contained in BGS Technical Reports WB/MG/73/46.

additional info: For more detailed information on the acquisition equipment and data collection techniques, operational standards, data processing methods and quality control procedures used on this survey see the Report of Survey/Cruise Report and associated documentation where available. The information available may vary depending on the age of the survey. Data are checked and loaded to the BGS Coastal and Marine data management system following BGS marine data management procedures.
