Summary Improvement in the accuracy of sea gravity surveys necessitates continuous computation of the errors involved. In a Mid‐Atlantic cruise a discontinuity was encountered across which the errors in gravity measurements changed sharply. Similarly, in a survey in the Bay of Biscay, successive lines showed large differences in the errors present. In the former case, elimination of the errors was not possible using an analysis of track intersection discrepancies and intermittent cross‐coupling evaluations. In the latter case, the almost continuous computation of crosscoupling errors enabled an accurate gravity map to be produced which was satisfactory for interpretation purposes.
