The offshore geoacoustic simulation using geoinformation systems
Abstract: The articles deals with the process of geoacoustic simulation carried out of a portion of shelf in geoinformation systems (GIS-systems) using the example of the Peter the Great Bay, Sea of Japan. The GIS-systems are represented by the ArcGIS packages used to store and visualise data on rocks of the shelf bottom. The data on the water layer are presented in the programme Ocean Data View, whereas the mathematical processing of the entire amount of the geoacoustic data was performed on the basis of the MatLab package. GIS-systems make it easier to work with the data on the geological structure and petrophysical properties of rocks, the physical properties of the aquatic environment and enable one to develop and visualise 2-D and 3-D models of the real environment. The developed algorithms for numeric geoacoustic model of the Peter the Great Bay were tried for the first time in the Russian Far East.
Key words: geoacoustic model, geoinformation systems, Peter the Great Bay.
