Composition of Fe-Mn nodules and crusts from the Cape Basin
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... -
Physiological and biochemical characteristics of Calanoides carinatus in wate...
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... -
Lipids in ocean particulate matter and bottom sediments
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... -
Chemical composition of Fe-Mn nodules and bottom sediments collected in the N...
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... -
Production of Zooxanthellae in the tropical Atlantic Ocean
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... -
