Chemical composition of Fe-Mn nodules from the Pacific Ocean
Calcareous and siliceous biogenic components have been studied in deep-water iron-manganese nodules from the northern and southern Pacific Ocean. Calcareous material consists of... -

Primary production in water column (P_p) varied from 107 to 312 mg C/m2/day in Yenisey Bay: from 25 to 63 mg C/m2/day in Obskaya Guba: and from 20 to 359 mg C/m2/day in the open... -
(Table 1) Abundance of radiolarians in the surface layer of bottom sediments ...
Two radiolarian assemblages are distinguished: an equatorial sub-assemblage of the tropical assemblage in the East Pacific Ocean, which differs somewhat from association of... -
Chemical composition of phosphorite nodules off Peru
Phosphorite nodules collected during Cruise 8 of R/V Dmitry Mendeleev off the Peruvian coast are represented by three lithologic types: friable, compacted, and solid. As the... -
(Table 1) Thickness of the Holocene layer and sedimentation rates in the Atla...
On the basis of planktonic foraminifera study, thickness of Holocene sediments has been ascertained in 60 sediment cores from various regions of the Atlantic Ocean. Ratios of... -
(Table 2) Chemical element contents in the surface sediment layer on the subm...
Paper devoted to geochemistry of antimony in metalliferous and transitional sediments from the Southeast Pacific. Contents are given on carbonate-free biogenic silica-free... -
(Table 1) Some structural characteristics of communities and detritus flux th...
Vertical fluxes of autochtonous detritus at different levels were estimated using the algorithm of structure-function analysis. The calculations are based on pelagic ecosystem... -
(Table 1) Composition of bituminous substances in sediments from the East Pac...
Bitumoid contents in metalliferous sediments from axial parts of the East Pacific Rise (EPR) have been studied. Maximal concentrations of bitumoid matter and aromatic... -
(Table 2) Radiolaria species in nodule samples from the Clarion-Clipperton pr...
Radiolaria were studied in 19 manganese nodules raised from the bottom. The nodules occurred mainly on the surface of thin Quaternary sediments covering Tertiary deposits of...
