Statement

Geophysical equipment types used included: Airgun/Sleeve Gun, Echo Sounder, Gravimeter, Magnetometer, Pinger, Sidescan Sonar, Sparker, Surface Tow Boomer and Transit Sonar. The survey was undertaken by British Geological Survey. Navigation: Magnavox satellite navigation system integrated with MX610 doppler sonar and Arma Brown Mk I Mod 5 gyro compass. Dacca Mk 21 main chain receiver - optional integration with above. Equipment: Bolt 600B air gun, two guns with standard (1-40 cu.in.) range of chamber sizes, Krohn-hite bandpass filter, TSS Model 307 TVG amplifier and display on an EPC 3200 graphic recorder, Geomecanique hydrophone system. Atlas Deso 10 echo sounder with hull mounted transducers (33 and 210KHz) and Edig 10 digitiser unit. LaCoste & Romberg S75 air-sea gravity meter. World Wide land gravity meter for base ties. Varian proton magnetometer, cycling controlled by seismic control to eliminate sparker interference. EG&G sparker system, with up to 5kJ capability. One 3-element and one 9-element spark array, Krohn-hite bandpass filter, TSS Model 307 TVG amplifier, TSS Mobel 302 swell filter and display on an EPC 4600 or EPC 3200 graphic recorder, Teledyne hydrophone system. UDI AS350 dual channel side scan sonar system with catamaran tow fish, 2500ft tow cable and remote controlled winch. Display on an EPC 3200 graphic recorder and firing sequence controlled by the seismic control system. Kelvin Hughes MS47 transit sonar with hull mounted, 2 off - one port and one starboard scanning. Modified for dual operation and display on an EPC 3200 recorder. Firing sequence controlled by seismic system. Edo Western 248 pinger, 3.5 KHz, 10KW transducer in tow fish assembly. Used with TSS Model 302 swell filter, display on EPC graphic recorder. Huntec deep tow boomer system with remote contrilled winch, Krohn-hite bandpass filter and display on an EPC 3200 graphic recorder. For more detailed information see the Cruise Report.
