Endogenous and exogenous factors at sediment erosion, transporting and accumulation in the North-East shelf of Sakhalin island

Abstract

The purpose of the research is to estimate the direction of sediment erosion, transporting and accumulation development from the sea coast to the shelf border. The author has determined the dependence of sedimentation character on geomorphologic and structural object association based on the results of engineering-geological survey of two areas of North-East shelf of Sakhalin island. The influence and interaction of endogenous and exogenous factors in geoecological processes were investigated. The endogenous factors are represented by geological conditions of the territory. The characteristics of exogenous factors are represented in geomorphologic and ocenological conditions. The paper describes current deposits and bottom-living forms of the relief from the sea coast to the shelf border. The paper introduces the pictures of sub-bottom profiles in analog format. The depth of analog recording is limited by the depth of the sea bottom.
