The integrated geological and geophysical expedition aboard the R/V Akademik Oparin to the Tatar Strait, Sea of Japan (cruise No. 54, 2017)

According to the Plan of Integrated Scientific Research of the World Ocean for 2017–2022, the Il’ichev Pacific Oceanological Institute, Far Eastern Branch of the Russian Academy of Sciences (POI FEB RAS) began a comprehensive study of the northern part of the Sea of Japan and the Tatar Strait, having developed a three-year plan for expeditionary research in the area. The first expedition from the three-year expeditionary research cycle was carried out from September 21 to October 31, 2017 on the R/V “Akademik Oparin” (cruise № 54). The main goal of the expedition was to study the geological structure, conditions and mechanisms for the formation of the Tatar Strait, to study the correlation of the distribution of gas-fluid flows with a network of tectonic disturbances of different ranks in one of the seismic areas of Sakhalin Island, as well as the reaction of the Sea of Japan to climate change and increasing anthropogenic impacts.
