Chemical compositions of Fe-Mn nodules and host sediments from the Northwest ...
A number of regularities of ore element accumulation in iron-manganese nodules along the profile from the Tsugaru Strait to the Wake Atoll is identified in the paper. It is... -
Uranium and radioactive isotopes in bottom sediments and Fe-Mn nodules and cr...
The main stages of the sedimentary cycle of uranium in modern marine basins are under consideration in the book. Annually about 18 thousand tons of dissolved and suspended... -
Composition of suspended matter and bottom sediments from the Atlantic Ocean ...
The book summarizes data on distribution and composition of sedimentary material suspended in waters of the Atlantic Ocean and its seas. Results of observations of Soviet and... -
Trace element contents in different types of recent bottom sediments from the...
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... -
Geochemical parameters of sediments and waters in areas of ocean barrier zones
Geochemical barrier zones play an important role in determining various physical systems and characteristics of oceans, e.g. hydrodynamics, salinity, temperature and light. In... -
Data on the biogeochemical cycle of methane in the ocean
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.... -
Occurrence of interlayers in sediment cores collected in the East Indian Ocean
In the East Indian Ocean direct contribution of land volcanism to sedimentation appears as interlayers of tephra and tuffaceous sediments, pumice fragments, and dispersed... -
Chemical composition of ferromanganese concretions and host bottom sediments ...
Ferromanganese concretions spread out on the bottom of the shallow northwest part of the Black Sea are mainly represented by Fe and Mn nodules on shells and substituted worm... -
Bottom invertebrates and madreporarian corals in the Canary upwelling area
Composition and distribution of bottom fauna, especially scleractinian and gorgonarian corals, collected in the area of the Canary upwelling are discussed. Five species of... -
Organic compounds and bitumen in surface sediments from the Pechora Bay
Detailed geochemical investigations of bottom sediments in the Pechora Bay were carried out under a monitoring regime. The regional geochemical background is characterized.... -
Composition and sorption capacity of oceanic and marine ferromanganese nodules
Experimental data obtained show that oceanic and marine ferromanganese nodules and crusts are natural ion-exchangers. Exchange capacity of oceanic ferromanganese aggregates is... -
Composition of micronodules and host sediments from the Guatemala Basin
A complex of mineralogical techniques used in studies of near-surface layer hemipelagic sediments indicates that disordered todorokite and hexagonal birnessite dominate in... -

Rock material sampled from the Mir manned deep-sea submersibles and by dradges, grabs, and sediment cores over a vast area of the North Atlantic was analyzed to show that this... -
Composition of bottom sediments from Mediterranean anoxis basins
Biomass and size structure of planktic infusoria communities were investigated in March 1987 at nine stations on a 370 mile transect across the coastal upwelling zone, the... -
Isotopic composition of carbon in organic matter of sediments and particulate...
A study was made of isotopic composition of carbon in lipids found in three samples of separate particulates and in eight bottom sediment samples collected in a from the... -
Chemical composition of sediments from the Indian Ocean
Intensive reduction processes within bottom sediments from the Bay of Bengal lead to marked enrichment of the oxidized layer in iron and manganese. This is not observed in... -
Planktonic foraminiferas in bottom sediments and Late Quaternary paleotempera...
Distribution of planktonic foraminiferal tests was studied in 15 Upper Quaternary sediment cores from the continental slope of Africa, the Canary and Cape Verde basins, and... -
