On June 13 researchers from INRTU, Karpinskii All-Russian Research Geological Institute (Saint-Petersburg) and Limnological Institute of SB RAS departed for the scientific expedition to study dangerous geological processes on Lake Baikal related to natural hydrocarbon travel. Geologists from Saint-Petersburg and radiophysicists and limnologists from Irkutsk plan to collect new data for the digital map of the lake and continue investigation of Baikal bottom morphology and bottom sediments structure. The expedition will use the equipment developed by the staff of INRTU Physical and Engineering Institute.
INRTU group of scientists is headed by Aleksandr CHENSKII, Head of the Department of Radio Electronics and Telecommunication Systems. He mentioned that it is the third joint expedition already.
“We worked at the point of max Baikal depth thoroughly. According to our data, it somewhat differs from the value 1642 meters set in 1938. We made a detailed map of this lake part and will soon publish a paper covering this topic. But in my opinion the most significant result of previous expeditions was the study of a large territory of the lake in the area of the Selenga River where such dangerous geological phenomenon as land erosion occurs. We furthermore mapped considerable territories of Northern Baikal”, A. CHENSKII told about some results of previous expeditions.
This year the routes of scientific vessels “G. Titov” and “G.Yu. Vereshchagin” run towards Bolshoe Goloustnoe settlement where extensive gas-hydrate fields were discovered. As scientists report, in order to prevent ecological system of Baikal from dangerous influence of hydrocarbon travel processes, it is necessary to carry out corresponding researches and monitoring. In particular, it is very important to investigate the level of stability of gas-hydrate stratum on Baikal bottom under the conditions of exceptionally high dynamic of modern geological processes.
INRTU research group is composed of almost all employees of the Division of Information-Measuring Systems of Physical and Engineering Institute: Dmitrii CHENSKII, Nikita GUBIN, Kirill GRIGOREV.
The scientific expedition will finish its work on June 23.
