Within the limits of the Far Eastern coastal seas and the northwest part of the Pacific Ocean there is a wide development of abrasional-accumulational planation surfaces. Information on the morphology and morphometry of the planation surfaces has been obtained as result of detailed work carried out by an expeditionary vessel with recording echo-sounders. From the echograms the edge-depth and slope of the planation surfaces were determined and mean values of these characteristics were calculated, both for the area of the explorations as a whole and also for the different seas and different sectors of the coastal shelf. Analysis of all the data premitted the demonstration of considerable differences in the edge-depth and slope of the planation surfaces, differences testifying to the presence of vertical movements of the crust.
