Biomass of seston in the surface layers of coastal waters off Namibia reaches 1 g/m**2 and decreases with distance from the shore. Two regions of high seston biomass, one...

New data obtained in a shipboard laboratory are used to illustrate effect exerted by lithology of enclosing rock and by early diagenesis on residu¬al organic carbon content of...

Facies zonation of the Cape basin with respect to Fe-Mn nodules based on data from Cruise 43 of R/V Akademik Kurchatov and published data is presented. Three facies regions are...

Biochemical composition, feeding and oxygen uptake rate of mass planktic copepod Calanoides carinatus were studied off the coast of Namibia in January 1986. Population of this...

Lipid contents both in particulate matter and bottom sediments decreases with passage from the shelf toward the open ocean. Lipid concentration in particulate matter collected...

Degree of development of heterotrophic nano- and microplankton in various ocean harbors subject to considerable anthropogenic effects is evaluated. Qualitative composition of...

The distribution of barite in sediments from D.S.D.P. sites 424 and 424A at the Galapagos hydrothermal mounds field is determined and the process of its formation is deduced....

A procedure is presented to separate diatoms and radiolaria from marine sediments and from each other, to purify them of elements associated with other phases, and to dissolve...

The fluorescence of porewaters from marine sediment cores from six different areas was measured. In most cases, fluorescence was affected primarily by the diagenesis of organic...

The Middle Paleozoic complex consists of terrigenous and volcanogenic materials metamorphized in greenschist facies. Clastic rocks have arkosic composition and are formed by...

Amino acid composition of bottom sediments on the northwestern continental slope of Africa is determined. Correlation similar to that found earlier in Caspian sediments between...

Findings made in 31 catches with an Isaacs-Kidd midwater trawl in the light (09.00-16.00) and dark (21.00-04.00) periods of a day within a survey area of about 100 sq. miles...

The number of cysts of marine planktic infusoria was determined in oligotrophic waters of the central Indian Ocean and productive waters of the Southeast Pacific. Cyst biomass...

Results of a study of phosphates collected on Pacific Ocean seamounts using some physicochemical methods are described. Particular attention is paid to isotopic studies of both...

Sedimentation rates (SR) for metalliferous and ore sediments containing ore material in 15 depressions of the Red Sea rift zone are discussed. SR for normal sediments was ca....

Concentration, distribution, and dynamics of yellow substance were studied during 1980-1982. Colored material accounted for 17-41% of dissolved organic matter and 2-14% of...

Results of a field study on distribution of 137Cs and 90Sr between water and bottom sediments in the Baltic Sea carried out in March-June 1980 are presented. Concentration of...

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...

Ore crusts from the Mid-Pacific Seamounts were studied by scanning electron microscopy and by atomic-absorption and chemical analysis. Characteristic ultramicroscopic structures...

Morphology, ecology, range and species composition of diatom algae mass accumulations that are biotypically associated with the lower surface of Arctic sea ice are discussed....
