The paper presents brief results of comprehensive studies of the water area of the Tatar Strait and Sea of Japan obtained on cruise 61 of the R/V "Akademik Oparin" in November-December 2020. The bottom relief and geophysical and gas-geochemical fields were refined, and new features of the geochemistry and mineralogy of bottom sediments were reveale...

AbstractThe article describes the geological conditions of the formation of cobalt-rich ferromanganese crusts on the Govorov guyot in the Magellan Seamount system of the Pacific Ocean. It is established that the crusts are deposited on dense organogenic-clastic limestones, breccias, and volcanoclastic rocks. Crusts are three-or four-layer formation...

AbstractA method is proposed for visualizing the inconstancy of the phytopigment composition in the water layer of the formation of backscattered solar radiation recorded by the MODIS multispectral ocean color scanner. The method relies on the fact that each pixel of the MODIS raster image of the investigated water area is assigned a wavelength ref...

AbstractThe meridional shift of the absolute dynamic topography (ADT) gradient field structure in the zone of the Antarctic Circumpolar Current (ACC) south of Africa (10° E–25° W) was analyzed over the observation period 1993–2018 based on ADT satellite altimetry data at https://marine.copernicus.eu. The study was carried out by an original method ...

Abstract—A fundamentally new microfluorimeter is designed to assess the functional state of primary photosynthesis in individual phytoplanktonic cells. The device is tested during a sea expedition. It allows estimation of the amount of photosynthetic pigments, the primary photosynthetic efficiency, the light slope of the linear electron-transfer ra...

AbstractThe paper presents the results of lithological, mineralogical, and geochemical studies of bottom sediments in the central part of the South Caspian Basin. A complex of analytical methods was used to identify authigenic minerals from groups of sulfates, carbonates, and sulfides; study their forms of crystals and aggregates and their composit...

AbstractAreas with different values of the bio-optical characteristics of the surface water layer and different temperature and salinity distributions obtained during a Transatlantic transect in winter 2019/2020 are studied. In the region of Canary Upwelling and the equator, the temperature decrease zones correspond to peaks of fluorescence intensi...

AbstractThe late-summer zooplankton features of the structure and distribution in the South Baltic and the Baltic Proper (deeps 55–215 m) in 2016 were revealed, taking into account hydrological conditions. The taxonomic diversity of zooplankton was higher in the Baltic Proper (surface salinity ~6.5 psu), and the total quantitative indicators of zoo...

AbstractAfter a long hiatus, integrated geological and geophysical studies resumed in the western South China Sea. The research was carried out on cruise 88 of the R/V Akademik M.A. Lavrentiev. The results of onboard geophysical works were supplemented with data from global magnetometry and satellite altimetry databases. Structural-density modeling...
