This report is presented in the format of a logical mode of investigation having general applicability in establishing a gravity prediction process for any oceanic area but applied specifically to the Atlantic Ocean. The presentation takes cognizance of the fact that there are gravity domains in which the basic relationship between gravity anomalies and regional changes in bathymetry varies; that plate tectonics plays a significant role in defining the boundaries of gravity domains; that long wavelength changes and lithospheric mass play a significant role in defining the rate and sign of change in free air anomaly values with change in water depth within a given gravity domain; and that changes in crustal age and crustal thickness and composition give rise to both local and semi-regional perturbations which, for the most part, can not be anticipated except where there is associated bathymetric expression or some geophysical parameter value related to gravity.
