Title

British Geological Survey (BGS) Geophysical Survey 1983/5: Irish Sea & English Channel (12/08/1983 to 30/08/1983)

Abstract

Report: Brett, CP. 1984. Operations Report on Project 83/05. Gravity and Magnetic Survey along WINCH and SWAT Lines and Regional Geophysical Survey in the Western English Channel. (IGS Report No 138). The primary objectives were to acquire gravity and magnetics data along the WINCH and SWAT seismic lines of the British Institutions' Reflection Profiling Syndicate (BIRPS), and to survey over suspected thrusts in the basement of the English Channel close to the South Cornish Coast. A secondary objective was to run infill gravity lines in the English Channel.

Lineage

Geophysical equipment types used included: Airgun/Sleeve Gun, Echo Sounder, Gravimeter, Magnetometer and Sparker. The survey was undertaken by British Geological Survey. Navigation: Magnavox satellite navigation system integrated with MX610 doppler sonar and Arma Brown Mk1 Mod 5 or Mk 1C gyro compass. Decca Mk21 main chain receiver - optional integration with above. Mk 21 lat-lon convertor. Equipment: Bolt 600B four guns with standard (1-40 cu.in.) range of chamber sizes, wave shape kits for 40 cu.in., BGS firing delay unit for synchronisation, Kemo bandpass filter, TSS 307 TVG amplifier and display on an EPC 4600 or EPC 3200 graphic recorder. Geomecanique 2 channel, 30m hydrophone system. Containerised Compare Reavell VHP 36 compressor system. Atlas Deso 10 echo sounder with hull mounted transducers (33 and 210kHz) and Edig 10 digitiser unit. 33kHz channel with selectable 7 or 19 element transducer for deep water operation. LaCoste and Romberg S75 air-sea gravity meter. Worden land gravity meter for base ties. Barringer proton magnetometer - two tow cable sensor assemblies. Cycling controlled by seismic control system to eliminate sparker interference. EG&G surface sparker system - up to 2KJ capability. One 3-element and one 9-element spark array, Kemo bandpass filter, TSS 307 TVG amplifier, TSS 302 swell filter and display on EPC 4600 or EPC 3200 graphic recorder. Teledyne 7 channel, 10m hydrophone system. For more detailed information see the Cruise Report.
