Physical Sciences: Deep Sedimentary Basin in the Moray Firth

Abstract

DURING May and June 1970, the Institute of Geological Sciences (IGS) undertook a seismic reflexion profiling (Sparker) and gravity survey in the Moray Firth along a network of lines spaced approximately 10 km apart. The Bouguer anomaly gravity map shown in Fig. 1 includes the results of the marine gravity survey, land survey results compiled from unpublished IGS data, some unpublished results made available by Drs W. Bullerwell and J. Phemister, and results of a survey published by McGregor and Wilson1. A previous survey using a sea bed gravity meter has been reported by Collette2, whose published map showed a similar pattern of anomalies. The wide and irregular spacing of the stations prevented satisfactory interpretation, however.
