Frequency analysis of topography applied to morphostructural subdivision of sea floor near Sakhalin

Abstract

Frequency analysis as applied to floor topography at the north Sea of Japan and north-west Sea of Okhotsk gave the results which seem to be in good agreement with geological and geophysical data available; it permits to obtain more specific information on the areas geology as well as to discern a series of new structural elements, The technique is recommended to be used on broad scale at the seas of the Far East together with geological and geophysical works at the regional studies stage in order to receive a general out-line of the geological situation.

While more detailed studies are carried on, some more sensitive processing technique can be used to outline local structures, individual blocks as well as to trace faultlines.
