Cruise Report on Project 80/01 (4 phases, gap between 5-18 June). A Regional Geophysical Survey in the Southern North Sea. (IGS Report No 103). The primary objectives were to complete the geophysical survey of the Indefatigable and Spurn sheets of the IGS 1:250000 map series, and to re-run several line surveyed in 1979 (Project 79/02) on the Flemish Bight sheet. A secondary objective was to run one line along a proposed pipeline route on the California sheet.
