INTEGRATED REPRESENTATION OF HYDROGRAPHIC DATA FOR STUDYING LAKE BAIKAL

The proposed paper outlines the main approaches to the integrated acquisition of hydrographic data on Lake Baikal using special geophysical equipment, the Kongsberg EM710S multibeam echo sounder, as well as the Knudsen CHIRP 3260 subbottom profiler. As a result, a digital model of the underwater surface near the village of Bolshoye Goloustnoye is presented. It made it possible to identify well-developed ridges and slopes along the underwater slope, as well as to determine the places where gas seeps out from the bottom.
Keywords: Lake Baikal, bathymetric survey, hydrographic works, hydroacoustic means, multibeam echo sounder, profiler, digital surface model.
