Age marks in bottom sediments of the Pacific Ocean
Distribution of K-Ar age marks in Pacific bottom sediments is shown on the base of large analytical material. Dependence of K-Ar age marks on abundance of potassium-bearing... -

Chemical composition in phosphate materials from the ocean floor
Content, distribution patterns, and speciation of Cl in phosphorites and bone phosphate from the ocean floor, as well as in a set of samples from the land are studied. Total Cl... -
Heavy metal speciations in plankton, suspended matter, and recent bottom sedi...
In the book based on original data speciations of iron, manganese, zinc and copper in dissolved and suspended phases, as well as in biota are under consideration. It is shown... -
Contents of P2O5 and REE in phosphorites from shelves and Pacific seamounts
Recent phosphorites from the Namibian shelf are characterized by low REE contents, depletion in REE compared to host sediments and sharp deficiency of lanthanum and europium. In... -
Microplankton abundance and biomass in the Eastern Pacific
Particles of detritus were counted by size-groups and microplankton cells in samples stained with acid fuchsin and acridine orange. Data were obtained for eutrophic and... -
