Geophysical equipment types used included: Airgun/Sleeve Gun, Deep Tow Boomer, Echo Sounder, Gravimeter, Magnetometer, Pinger, Sparker and Transit Sonar. The survey was undertaken by British Geological Survey. Navigation: Magnavox satellite navigation system integrated with MX 610 doppler sonar. Decca Mk21 Main Chain. Equipment: Atlas Deso 10 echo sounder with digital readout unit (Edig 10). LaCoste & Romberg air-sea gravity meter S75 with LaCoste & Romberg 9400 data acquisition system. Two Barringer magnetometers. Edo Western 248 pinger with hull mounted transducers. IGS multi-element spark array and EG&G 9 candle and 3 candle spark arrays. Two 30m Geomechanique hydrophones and one 50m Geomechanique hydrophone. Project 79/16 was designed to provide regional geophysical coverage of the south North Sea in the British sector between 52N and 53.5N on a primarily NS-EW grid of lines at approximately 7.5km by 9km spacing. The information obtained from the shallow seismic equipment was to be used as a basis for drilling and sampling by IGS, CSSU later in the year. Gravity and mangetic equipment were also carried to supplement work carried out in 1978. The 4kJ and 800J sparkers were run for most of the second leg, giving penetration of up to 700m and 150m respectively, with approximately 8m resolution on the 800J records. During the third leg the 1kJ sparker was run as an alternative on a number of lines. During leg 4, the 500J sparker gave penetration of up to 100m with improved reflector resolution over previous legs. The 4kJ sparker worked well though mains interference marred some lines. The pinger provided good definition in the top 20m below seabed and enabled the tracing of two major channel systems across the survey area. For more detailed information see the Cruise Report.
