Multiyear monitoring of the marine environment of the Japan/East Sea was continued by the joint Korean–Russian expedition of the R/V Akademik Oparin (cruise 58) in October–November 2019, including changes in the sea circulation and ventilation and biogeochemical processes as a result of current climate changes and growing anthropogenic impacts. Studies of mesoscale eddies associated with the branches of the Tsushima Warm Current have been continued. Methane flare has been discovered for the first time at the eastern Primorye slope.
