Ultrafiltration with tagged atoms was used to study physicochemical states (dissolved, colloidal, suspended) of Mn, Co, Ni, Zn, and Ce in bottom and interstitial waters... -
Zooflagellate production in the Central Indian Ocean
Multiplication rate and production of zooflagellates were determined in the Central Indian Ocean. In the surface zone of the areas studied zooflagellate generation time ranged... -
Adenosine triphosphate concentrations and microplankton biomass in sea water ...
ATP distribution in coastal waters off Peru was examined and was found to differ with hydrological conditions in this area; maximal values in the vicinity of an intense... -
Contents of 230Th, Fe2O3, MnO and P2O5 in bottom sediments from the Tropical ...
Shape of the 230Th vertical distribution curve ideally close to exponential is studied to determine isotopic age of deep-sea sediments. In practice such ideal 230Th vertical... -
Contents of radioactive elements, main chemical composition, and sedimentatio...
Gamma-spectrometric analysis was used for six sediment cores from the area occupied by metalliferous sediments in the Southeast Pacific. In five of these cores vertical... -
Contents of P2O5, Corg, Sr, and Ba in phosphorites and host sediments from th...
Sr contents in phosphorites on shelves of the Southwest Africa, and of Chile and Peru increase with degree of their lithification, from 0.05 to 0.28% and from 0.13 to 0.16%... -
Chemical composition of phosphorites from the Peru and Chile shelves
Recent and Late Quaternary shelf phosphorites have low Fe, Ti and Al contents. These elements enter the phosphorites with terrigenous impurities and organic detritus. Ti, Al,... -
Radiocarbon age of bottom sediments from the Atlantic and Pacific Oceans
Procedures for radiocarbon dating of ocean sediments on board the ship using the benzene variant of the method are described. The main features of the benzene synthesis scheme,... -
