Abstract:
The ocean, as a whole, has different value of anomalies, however, small anomalies within the limits of -35 - 10 mgals prevail. A value in the order of -25 mgals can be accepted as the mean anomaly. There are only few considerable anomalies. The number of points, with the given value of the anomaly, rapidly decreases in proportion to the increase of the anomaly. Against a background, closely related to the accidental distribution of anomalies, a dependence of anomalies on depth, in the order of -11 mgals per 1000m, occurs. In proportion to the increase of depth, the number and absolute value of negative anomalies increase till the complete disappearance of positive anomalies at great depths in the order of 6000m. After establishing the dependence of anomalies on depth, and evaluating the degree of deviation of actual anomalies from this dependence, it is appropriate to examine the possibility of using gravity anomalies for the determination of the sea depth, as well as for the evaluation of anomalies of gravitationally non-investigated regions, with respect to known depths. The problem of the dependence of anomalies on depth is important, for instance, for studies of the thickness of glaciers. Equally important is the problem of the determination of anomalies relative to depth.
