Chemical analyses of Fe-Mn nodules from the Indian Ocean
Mn nodule samples were decomposed with HCl and fumed with H2S04. SiO2 was estimated by the standard procedure of HF. The residue, after the removal of SiO2, was fused with... -
Uranium concentration in manganese nodules recovered from the Pacific Ocean d...
Uranium was measured in manganese nodules by alpha-ray spectroscopy after grinding and dissolution. The study included the separation of various rinds (layers) in the rind of... -
Chemical composition of Pacific manganese nodules and crusts analyzed at Scri...
23 manganese nodules and crusts from 17 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were... -
Atomic absorption spectrophotometry (AAS) chemical analysis of selected eleme...
Mn nodules from the Pacific and Indian oceans were retrieved during expeditions of the R/V Vytiaz and analysed for their chemical composition using Atomic absorption... -
Contents of cadmium, iron and manganese in various parts of manganese nodules...
Mn nodules and ferromanganese crusts from the Pacific ocean were retrieved during expeditions of the R/V Vytiaz and analysed for their chemical composition. Cadmium contents... -
Wet chemical analysis of selected elements in ferromanganese nodules from the...
Mn nodules from the southern central Pacific Ocean were retrieved during expeditions of the R/V Vytiaz and analysed for their chemical composition using wet chemistry... -

The data given in this and previous communications is insufficient to assess the quantitative role of these supplementary sources in the Indian Ocean, but they do not rule out... -
Description and analysis of ferromanganese nodules in the Pacific Ocean
Ferromanganese nodules in the Pacific Ocean were analysed. From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles,... -
Description and composition iron-manganese concretions from the Pacific
One the most interesting features of ocean sedimentation is the manganese formations on the surface of the ocean floor in some areas. These are especially widespread in the... -

Sedimentation rates in the Reykjanes rift near 58°N have been measured on the base of radiocarbon datings of bottom sediments collected during Cruise 4 of R/V Akademik Mstislav... -
(Table 1) Carbohydrates in different sediment types of the Central Pacific
Total contents of carbohydrates were determined in samples of natural sediments of various genetic types. Analyses were made on board. Deep-sea pelagic sediments (red clays of...
