Abstract : A comparison of the results of aeromagnetic and gravimetric surveys and of the deep seismic sounding data enables us to make certain conclusions about the nature of magnetic and gravity anomalies in the region under study. The sources of magnetic anomalies in different structures of the Sea of Okhotsk are confined to the upper part of the granitic layer and to the bottom portions of this layer or the upper part of the basaltic layer. In the Pacific ocean, off the shores of the Kuril Islands, the anomalies are related to the very upper part of the Earth's crust section; east of the abyssal trench axis, - to the basaltic layer and probably to the upper portions of the subscrustal layer. A comparison of the gravitational field and the Earth's crust sections obtained by deep seismic sounding makes it possible to point out regions of an anomalous density of the subcrustal matter.
