near Diomede Stones Island, w...
We have investigated the interaction between the mesoscale and submesoscale eddies in the deep Kuril Basin of the Sea of Okhotsk. An analysis of the long-term series of satellite altimetry observations (2000-2011) has demonstrated that the circulation in the Kuril Basin is determined by quasi-stationary mesoscale anticyclonic eddies. Based on the Q...

The Japan/East Sea is well ventilated to the bottom, through processes of subduction, open ocean convection, and brine rejection from sea ice production. The Japan/East Sea has a relatively short overturning time scale, and thus its deep and bottom water properties are in flux, tied to changing surface conditions with a delay of only decades. Conce...
During cruise 29 of R/V Akademik Oparin (July 2003), a comprehensive study of the ecosystem of the Amur River estuary was performed. The data obtained during the cruise allow one to study the spatial variability of the hydrochemical and hydrological parameters in the zone of mixing of riverine and sea waters in the Gulf of Sakhalin of the Okhotsk S...
In the summer of 1999 and the winter of 2000, during international expeditions of R/Vs Professor Khromov and Roger Revelle, hydrological and hydrochemical studies of the Sea of Japan were performed. Comparing the hydrochemical characteristics of the Sea of Japan in the summer and winter seasons, we have found that the seasonal variability affects n...
Direct water mass renewal through convection deeper than 1000 m and the independent process of dense water production through brine rejection during sea ice formation occur at only a limited number of sites globally. Our late winter observations in 2000 and 2001 show that the Japan (East) Sea is a part of both exclusive groups. Japan Sea deep conve...
Characteristics of high-salinity intermediate water in the northern region of the Japan Sea are studied from CTD data.

Vinogradov" in April-May 1991 and in August 1992. Anthropogenic CO2 distribution atthe isopycnal sur faces in different structural zon...
VENTILATION OF THE OKHOTSK SEA INTERMEDIATE WATER IN THE SEA OF OKHOTSK
Intermediate waters in the Okhotsk Sea can be ventilated by two processes, i.e., the formation of hight -density shelf water in coastal polynyas and winter convection in the zone of the Soya Current. Based on CTD data (July-September 1994) an analysis of temperature and salinit...
CTD data and hydrochemical measurements in the Sea of Okhotsk in spring 1995 are used to analyse the spacial and temporal variability of the water structure and water mass modification in the Kruzenshtern Strait. The Okhotsk Sea water occupied the southern part of the strait, while the Pacific water were in the northern part. The highest variabilit...
Features of anthropogenic CO2 distribution with depth and at isopycnic surfaces in different structural zones of the West Pacific Subarctic are considered.

CTD data are used to study the relationship between the temperature field fine structure and the location of the frontal zones and synoptic eddies in the region adjacent to the eastern coast of the Kamchatka peninsula. High levels of fine structure activity were observed in the frontal zone of the East Kamchatka current and in the peripheries of an...
From results of satellite-IR images, the Amur River fresh water discharge in the near mouth area and continental shelf of the Okhotsk Sea was analysed. The most typical cases of plume formation and disposition in the surface layer resulting from mixing of the river and sea waters in the summer-autumn period were identified. On the basis of CTD obse...
Based on mean multiyear temperature and salinity data structural zones and layers are isolated. Within their limits there are favourable conditions for the development of processes such as layer convection and salt fingers. It is shown that distribution of their parameters is conditioned by location of intermediate water mass boundaries and front i...
about 390 km3 from a river basin of 1,855,000 km2. The regime of the Amur River is distinguished by the spring-summer flood, summer low water, summer- fall flood, and winter low water. The spring flood is caused by melting snow and the summer-fall flood is caused by monsoon rains in the river basin. About 87% of the annual discharge falls during th...
The three marginal seas of the northwest Pacific have very different impacts on North Pacific water mass formation, primarily because of differences in salinity which is mainly a function of proximity to the subtropical gyre. The other major difference is the depth of sills separating these seas from the North Pacific. The Japan Sea is the farthest...
Two separate winter water mass formation experiments were carried out in the north- western Pacific. The Japan/East Sea (JES) is well-ventilated to the bottom (3500 m depth), and is much better ventilated than the adjacent North Pacific at the same depth and density. Winter data from 1999 and 2000 show that the JES is one of the few sites in the wo...
