Abstract—Based on the shipboard measurements data, GTOPO1 and ASTER satellite information, GEBCO
databases, and bathymetry maps, a digital elevation model encompassing the shelf of Peter the Great Bay of the
Sea of Japan is constructed. By two-dimensional singular spectral analysis, the scale decomposition of the sur-
face of the shelf relief is made into the components with the main tectonic structure, the secondary folding
zones, and the sedimentation landforms. A comparison between the found elements and the geological data on
South Primorye is performed to specify the age of the tectonic units of different scale.
