Gravity anomalies, regional elevation, and the deep structure of the North Atlantic

central portion of the ocean and a large area of very negative anomalies in the western basin. The negative anomaly in the western North Atlantic has no expression in residual depth anomalies and does not appear to be related to surface features. The North Atlantic Gravity High is bounded on the south by an important and distinct boundary near 30oN which is present in both depth and gravity anomalies. North of this latitude, residual gravity anomalies (corrected for the 'ridge anomaly') take the form of a very broad high of about 20 mGal with the values along isochrons nearly constant from 30oN to at least as far north as 75oN. The depths within this region are consistently shallow with 5 o X 5 o average residual depth anomalies which vary greatly from a few hundred meters near the Charlie Gibbs fracture zone to a few thousand meters near Iceland and the Azores. We used three-dimensional spherical earth models to investigate simple compensated mass distributions which could explain the observed depth and gravity anomalies. The acceptable family of models has the common characteristics that within the anomalous region north of the 30oN boundary a portion of the compensation must be distributed to depths of several hundred kilometers and that this deep mass deficiency must be nearly uniform throughout the area. However, the compensation for more local features within this region must be shallow (within the lithosphere). Thus the topographic highs surrounding Iceland and the Azores are compensated within the
