To resurvey the Peterhead and Forties sheet of the IGS 1:250 000 map series. The area had been previously surveyed in 1972. During the 1972 cruise there were considerable technical problems with the gravity meter and much of the data was of only moderate quality. Since 1972 subsequent surveys in adjacent areas further emphasised the inadequacies fot he data and it became apparent that the area needed to be completely resurveyed.
