ObjectivesProject 79/02 was designed to provide regional geophysical coverage of the south North Sea in the British sector between 54°N and 52°N on a primarily NS-EW grid of lines at approximately 7.5km by 9km spacing. The information obtained from the shallow seismic profiling equipment, including a deep towed boomer system was to be used as a basis for drilling and sampling by IGS, CSSU later in the year. Gravity and magnetic equipment were also carried to supplement work carried out in 1978.
