Ferromanganese nodules found in regions of hilly relief of the ocean bottom are associated with facies of high carbonate or non-carbonate deep-sea sediments characterized by...

The radiocarbon method was used to measure primary production of Zooxanthellae of five colonial radiolaria and two pelagic foraminifera from the tropical Atlantic Ocean; in...

It is found that hydrocarbons are constantly accumulated on the main geochemical barriers: water-atmosphere, river-sea, water-suspended matter, and water-bottom sediment...

Results of four year (1977-1980) observations on concentrations of organochlorine pesticides in waters of the North Atlantic (between 10°N and 60°N) are presented. Gas-liquid...

Two lithological-stratigraphic intervals have been distinguished in the Morocco basin by a study of lithologic composition of bottom sediments as well as of planktic and bottom...

Results of radiocarbon dating of bottom sediments from the Baltic Sea are presented for four areas investigated during Cruises 16 and 26A of R/V Akademik Kurchatov. The dating...

Total mercury concentration in waters of the Atlantic Ocean and Mediterranean Sea measured in January-April 1982 varied from 0.007 to 0.192 µg/l. Particulate form was 1.6-16% of...

An automated system is described for collecting and processing information from radiometric devices used in determination of isotopic age and sedimentation rate by radiocarbon...

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,...

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...

A study of distribution of live individuals of benthic foraminifera in sediments of the Sea of Okhotsk and of the Northwestern Basin of the Pacific Ocean shows that they can be...

Distribution of urea in different water layers of the northwestern Indian Ocean is described. It was found to be non-uniformly distributed. High concentration was found in...

Calculations of new production (NP) are made based on hydrochemical characteristics, recycling production (RP) is assessed on the basis of recycling of phosphorus and nitrogen....

Results of investigation of various forms of oil pollution, i.e. oil films, tar, and hydrocarbons in the Northeast Atlantic Ocean and North Indian Ocean during October-December...

Species composition, phytoplankton abundance, and relative yield of variable fluorescence (F_v/F_m) were determined in the mesotrophic Nhatrang Bay in October-November 2004....

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...

Concentration of dissolved and suspended organic carbon in the Barents Sea decreases with increasing depth and in meridional direction from south to north. This fact is...

Composition of alkanes present in total plankton was determined at two stations in the Gulf of Riga and in six samples of recent bottom sediments collected in a cross-section...

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...

Distribution of planktonic foraminiferal tests was studied in four drill cores of Upper Quaternary sediments from the zone of influence of the Canary upwelling and in nine...
