Analysis of rare earth element (REE) distribution and behavior in ore-bearing hydrothermal-sedimentary deposits from the Red Sea is carried out. Geochemical patterns and...

Trace element contents in different types of recent botoom sediments of the Indian Ocean are given. Sediment samples were obtained during cruises of the P.P. Shirshov Institute...

We characterize the textural and geochemical features of ocean crustal zircon recovered from plagiogranite, evolved gabbro, and metamorphosed ultramafic host-rocks collected...

Lower ocean crust is primarily gabbroic, although 1-2% felsic igneous rocks that are referred to collectively as plagiogranites occur locally. Recent experimental evidence...

Geochemical barrier zones play an important role in determining various physical systems and characteristics of oceans, e.g. hydrodynamics, salinity, temperature and light. In...

The book summarizes results of long-term studies of sulfur geochemistry in bottom sediments of seas and oceans. Processes of hydrogen sulfide formation in bacterial reduction of...

The measurements were obtained during two North Sea wide STAR-shaped cruises during summer 1986 and winter 1987, which were performed to investigate the circulation induced...

An original method of paleotemperature analysis on planktonic foraminifera is substantiated and actively used for stratigraphy of bottom sediments and paleoceanologic...

Geological, mineralogical and microbiological aspects of the methane cycle in water and sediments of different areas in the oceans are under consideration in the monograph....

The genus Calyptogena (Bivalvia: Vesicomyidae) comprises highly specialized bivalves living in symbiosis with sulphur-oxidizing bacteria in reducing habitats. In this study, the...

Concentrations of labile dissolved forms of Cu, Zn, Pb, and Cu in waters of the Kara Sea and Ob and Yenisey estuaries measured on board during Cruise 49 of R/V Dmitry Mendeleev....

Data obtained during Cruse 49 of R/V Dmitry Mendeleev and of post-cruise studies. Supplement to: Gurvich, Evgeny G; Isaeva, Alexandra B; Dyomina, L V; Levitan, Mikhail A;...

Correlation between the Azooxantellate Scleractinian coral distribution and abundance of zooplankton in the Atlantic Ocean was discussed. The analysis was based on a dataset of...

Data are presented on concentration of hydrocarbons (HC) relative to concentrations of suspended matter, lipids, organic carbon, and chlorophyll a in surface waters and snow-ice...

During Cruise 54 of R/V Akademik Mstislav Keldysh macrobenthos of the Novaya Zemlya Trough was studied with use of a Sigsby trawl along a submeridional transect near 75°30'N at...

Composition and distribution of macrobenthic communities in the Ob estuary (Obskaya Guba) and the adjacent Kara Sea shelf were studied during Cruise 54 of R/V Akademik Mstislav...

Calculated and measured estimations of biomass of small (<3 mm), large (3-30 mm), and total zooplankton were verified (compared). These integral parameters of epipelagic...

Data are presented on concentrations of aliphatic and polycyclic aromatic hydrocarbons (AHC and PAH) in interstitial waters and bottom sediments of the Kara Sea compared to...

The raw material for these investigations are samples from marine (sub)surface sediments around the northern part of the Antarctic Peninsula. They had been sampled in the years...

In the East Indian Ocean direct contribution of land volcanism to sedimentation appears as interlayers of tephra and tuffaceous sediments, pumice fragments, and dispersed...
