Vertical distribution of total zooplankton biomass and major taxonomic groups are investigated by layers to depths of 2500-3400 m on the basis of three series of net plankton...

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%...

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,...

Vertical distribution of common zooplankton species is examined on the base of two series of layer-by-layer net catches down to depth of 3400 m. Differences between the series...

Constants of calcium, magnesium, zinc, cobalt, copper, and nickel exchange for sodium in iron-manganese nodules taken from different parts of the Pacific Ocean were determined...

Accumulation rate of dissolved organic matter (DOM) by natural populations varies over a wide range. In the surface layer of the Black Sea accumulation rate of glucose is...

Distribution of ammonium, nitrite and nitrate nitrogen is examined in a section along 65-67°E between 18°S and 23°N during the transition period from winter to summer monsoons....

Group composition of organic matter in recent ocean sediments with high Corg content has been studied in detail. It has been shown that organic matter in sediments with Corg...

Authigenic phosphorite crusts from the shelf off Peru (9°40°S to 13°30°S) consist of a facies with phosphatic coated grains covered by younger phosphatic laminite. The crusts...

Study of morphology of clay minerals formed in altered submarine basalt flow lava has shown that clay-forming process was a continuous-discontinuous one. Basaltic glass was the...

Detailed petrochemical and geochemical studies of two samples of palagonitized basalts collected from depths 3060 and 4800 m have shown that palagonitization of tholeiitic...

Surface and upper-layer pollution of seas and oceans by crude oil and refinery products is under study by investigators in many countries. The Intergovernmental Oceanographic...

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,...

Bituminologic analysis of sediment cores from the Black Sea (water depth up to 2000 m, drilling depth up to 625 m) has revealed all components typical for fossilized rocks, viz....

Vertical distribution of proteinous substances in particulate matter from the central Black Sea is given. Sensitivity of determinations is not less than +/-20 µg of ''albumin...

Vertical structure of the strontium-90 concentration field and its relation to hydrology of waters are described on the basis of investigations in the Caribbean Sea during...

Abundance of microzooplankton was studied from August to October 1970 in a ship laboratory using the method of concentration of water samples by filtration and then counting...

Average total organic carbon concentration in the Norwegian Sea waters varies from 1.93 mg C/liter at depth of 10 m to 1.25 mg C/liter at depth of 2000 m, which is close to...

During Cruise 50 of R/V Vityaz ichthyoplankton in surface waters was collected by a neuston otter trawl for many days in four study areas of the Western Tropical Pacific....

Data are presented on concentration of dissolved organic carbon and particulate organic nitrogen in sea water at four stations, and also of dissolved and particulate amino acids...
