Tendencies of climatic and anthropogenic changes of the marine environments in the coastal areas of Russia in the Japan Sea for the last decades
Complex assessment of the marine environments changes in the coastal zone of the Japan Sea at Primorye and Sakhalin coasts is presented for the last 4 decades. Both natural and anthropogenic aspects of these changes are considered with the tasks: 1) to compare interannual variability of oceanographi...

Complex assessment of the marine environments changes in the coastal zone of the Japan Sea at Primorye and Sakhalin coasts is presented for the last 4 decades. Both natural and anthropogenic aspects of these changes are considered with the tasks: 1) to compare interannual variability of oceanographic parameters, as water temperature, salinity, and sea level, and reveal distinctions and common tendencies; 2) to define indicators of chemical pollution and find general features of interannual dynamics for polluting substances and water quality. The data of regular oceanographic observations at 11 coastal stations and the data of pollution monitoring in certain areas conducted by hydrometeorological service of Russia (Roshydromet) in 1980-2015 are analyzed. Cyclic fluctuations with the period of 2-5 years prevail in year-to-year variability of oceanographic parameters being observed on the background of long-term trends, more significant in the 21st century.
