MAPPING OF DANGEROUS GEOLOGICAL OBJECTS AND PROCESSES AT THE NORTHERN AND CENTRAL PARTS OF THE BARENTS SEA SHELF ACCORDING TO THE HYDROACOUSTIC DATA FROM RV “AKADEMIK NIKOLAI STRAKHOV”

Mapping of dangerous geological objects and processes by hydroacoustic methods is being intensively developed in the areas of the Arctic shelf of Russia. Considerable experience has been accumulated in identifying of these objects and in compiling of thematic maps showing their properties, spatial distribution and correlation with geological and tectonic structures. A large amount of data and the development of economic activity make it necessary to develop a methodology for compiling these maps, design of legends and an approach to updating them. The paper presents map samples of dangerous geological objects compiled according to the data of RV “Academik Nikolai Strakhov” expeditions.
