Composition of recent carbonate bottom sediments from the Guiana shelf an off...
This work was based on a study of the upper layer of recent carbonate bottom sediments of the Atlantic Ocean. Biogenic carbonate of recent sediments is represented by metastable... -
Sulfur speciation in bottom sediments from deep-sea basins of the Atlantic Ocean
Distribution of reduced sulfur forms in vertical sediment sections in deep-sea basins of the Atlantic Ocean is under study. Presence of weak sulfate reduction process resulted... -
Concentrations of Fe, Mn, Cu, Zn, Co, Ni, Pb, Cd, B, and SiO2 in interstitial...
Chemical analyzes show that interstitial waters from ore-bearing bottom sediments of the Atlantis II and Discovery Deeps are enriched in Fe, Mn, Cu, Ni, Co, Zn, Pb, and Cd... -
Oxygen isotopic and species composition of planktonic foraminiferas in sedime...
Paleotemperature curves were drawn from oxygen-isotope ratios in CaCO3 of planktonic foraminiferal tests and by the micropaleontological method using quantitative relationships... -
Carbon isotope composition of lipids from bones and host sediments of the Atl...
Carbon in lipids separated from organic matter of fish and marine mammal bones from bottom of the Pacific and Atlantic oceans has d13C values ranging from -21.6 to -25.8 per mil... -
Gold and organic carbon in waters from the Bering Sea and the North Pacific
Atomic absorption spectroscopy is used to determine concentration of gold in waters of the Bering Sea and North Pacific. Distributions of gold and organic carbon in colloidal... -
Planktonic foraminifera and Quaternary paleoceanology of the Atlantic Ocean
An original method of paleotemperature analysis on planktonic foraminifera is substantiated and actively used for stratigraphy of bottom sediments and paleoceanologic... -
Chemical and mineral compositions of bottom sediments and ferromanganese crus...
Results of study of bottom sediments near Iceland and on the Jan Mayen Island are reported. It was found that in recent sediments chemical elements are mainly associated with... -

Observation of manganese deposits in the the Jan-Mayen Ridge area during the ...
On cruises 10 and 15 of Academic Kurchatov (1971, 1973) at the Jan-Mayen Ridge, a large number of samples was obtained. Most of them contained sedimentary rocks. From their... -
Analytical results on palagonite samples and manganese crusts from the Mid-At...
A suite of three palagonites from pillowed basalts collected from within the Mid-Atlantic Ridge rift valley between 25°N and 30°N wer analysed along with another suite of two...
