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...

Paleotemperature curves were drawn from oxygen-isotope ratios in CaCO3 of planktonic foraminiferal tests and by the micropaleontological method using quantitative relationships...

Current understanding of rare earth element (REE) geochemistry in the ocean is given in the book. Chemical properties determining REE migration ability in natural processes,...

The book is devoted to investigations of benthic fauna and geology of the Southern Atlantic Ocean. These works have been carried out in terms of exploring biological structure...

Data from the Appendix to the PhD Thesis of the author. Supplement to: Gurvich, Evgeny G (1977): Microelements in bottom sediments from the Southeast Pacific. PP Shirshov...

Application of nuclear geochronology methods in study of recent sedimentation processes, in paleoceanology, tectonics, geomorphology, and other problems associated with...

Recent phosphorites from the Namibian shelf are characterized by low REE contents, depletion in REE compared to host sediments and sharp deficiency of lanthanum and europium. In...

Nuclei of Fe-Mn nodules and bottom sediments along a profile: Guiana Basin - Mid-Atlantic Ridge - Canary Basin have been studied by different methods. Tectoedafogenic and...

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...

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...

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...

Data on concentrations of the major ions (Cl, SO4, Alk, Na, K, Ca, Mg, NH4) in interstitial waters from sediments of three brine-bearing deeps of the Red Sea rift zone are...

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...

Contents of mercury and zinc in reduced sediments and interstitial waters of the Gdansk Bay in the Baltic Sea were investigated. It was found that sediments contain 0.7 ppm Hg,...

A bottom station (lander) was installed onto the bottom at station 6214 during Cruise 86 of R/V Professor Shtokman. Resulting from this installation, all the systems of the...

On the basis of a long term research of the authors a database model of grain size composition of unlithified marine and ocean bottom sediments has been created. An improved...

The book is devoted to study of diagenetic changes of organic matter and mineral part of sediments and interstitial waters of the Pacific Ocean due to physical-chemical and...

The book deals with behavior of phosphorus and its concentration in oceanic phosphorites. The major stages of marine geochemical cycle of phosphorus including its supply to...

The book provides an overview of recent data on processes of dispersion and concentration of phosphorus in marine sedimentation. Distribution, chemical and mineral compositions,...
