摘要
As a result of investigation carried out in 2005-2006 in the northern coastal zone of the Russian part of the Gulf of Finland the new data on geological history and modem sedimentation processes have been obtained. For the first time the side-scan-mosaic scheme of investigated area was developed. Side-scan sonar data analysis permits to distinguish some important features of the bottom structure such as glacial till ridges, dynamic sands (with ripples on the surface) zones, sand waves, erosion margins (valleys), technogenic relief and objects.
