GRAVIMETRIC INVESTIGATIONS IN THE REGION OF KURIL-KAMCHATKA TRENCH AND THE NORTHWESTERN PACIFIC IN 1958.

In accordance with the International Geophysical Year of 1957-1958, the complex operations on the study of the Kuril-Kamchatka transition zone from the Asian continent to the Pacific Ocean were included in the plan of Soviet Investigations. The main geophysical observations were carried out in the northern part of the transition zone, which covers the Sea of Okhotsk, the Sakhalin Island, the northern group of the Kuril Islands, the southern part of Kamchatka, the Commander Islands, and the adjacent part of the Kuril-Kamchatka bathypelagic depression. The geophysical observations in question were performed by seismic, seismological, gravimetric and magnetic methods. Deep seismic sounding was the main method of this multiple investigation. Author
