Selected manganese nodules both from deep-sea environments of the Pacific Ocean and epicontinental near-shore areas (Canada west coast and Baltic Sea) have been studied to...

Five manganese nodules from a range of deep-sea and fossil environments were selected for this study. Most samples were prepared for bulk analysis by grinding the material...

For evaluating the efficiency of high-temperature sulfation as a potential technique used in the extraction of metals from manganese nodules, the authors have chemically...

A variety of manganese nodules from the Pacific Ocean were selected from dredge performed during various ship cruises of the Scripps Institution of Oceanography (SIO. For Mn and...

11 stations were occupied during the survey carried out by CCOP/SOPAC on the UNDP charter vessel MACHIAS over an area southeast of Tarawa, western Kiribati. Retrieved manganese...

X-ray emission spectroscopy (XES) was used to analyse manganese nodules and crusts from the Pacific Ocean retrieved during expeditions from the Scripps Institution of...

Atomic absorption spectrophotometry (AAS) was used to analyse manganese nodules and crusts from the Pacific Ocean retrieved during expeditions from the Scripps Institution of...

Marine manganese nodules dredged from five locations in the central Pacific Ocean were studied for their mineral composition in todorokite. They were compared with pisolitic...

Selected manganese deposits from the Hawaiian Archipelago were submitted to chemical analysis using two methods. Atomic absorption spectrophotometry was used for the analysis of...

Manganese nodules and crusts from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using atomic absorption spectrophotometry (AAS). Samples were ground to...

Manganese nodules, coatings and crusts from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were ground...

Bottom dredging during the KK84 campign of the R/V Kana Kenoki recovered numerous ferromanganese crusts on a large variety of substrate (basalt, volcanics, limsetone and...

Ocean clay samples associated with ferromanganese nodules and crusts have been analysed for their 143Nd/144Nd isotopes ratio. Nd is separated from samples after HF-HNOa...

Sediment samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and minor element...

Oceanic manganese nodules samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and...

The paper presents the results of studies of ferromanganese deposits in the Hawaiian Archipelago. The chemical composition of ferromanganese oxide crusts and their associated...

142 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). From 1983 until...

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...
