SOME ASPECTS OF THE NARROWBEAM ECHO SOUNDING IN MARINE GEOMORPHOLOGY

Abstract

The study of small (from 1 to 1000 m) features of the bottom topography, which is very important fer geomorphological investigations, has become possible after the invention of oarrowbeam echo sounders which give a precise profile of bottom topography. The advantages of the narrowbeam echo sounding are shown by data obtained during the scientific expeditions on the r/v «Academician Kurchatov» and «Oceanographer».
