Mn crust samples were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line Islands Archipelago between 15°S and...

The chemical composition of ferromanganese crusts retrieved during the KK84 cruise of R/V Kana Keoki was determined using methods developed by Toth, J. R. from Oregon State...

The dredges and cores described in this report were taken on KK84-04-28 and KK84-08-24 expeditions in June-August 1984 by the Hawaii University (HIG) from, the R/V Kana Keoki. A...

The samples used for this study are a subset from almost 200 surface samples from the western Nazca plate analyzed during the IDOE Nazca Plate Project. The subset was selected...

Manganese nodules and crusts from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were ground to < 74...

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

Manganese nodules were taken from free-fall grabs at various stations of the Manganese Nodule Program BOMDROP cruise MN75-03. The underlaying sediment was essentially a...

Manganese nodules were retrieved during the KK72 (Midway 72-07-02) campaign using a CNEXO free-fall grab system. Selected samples were chemically analysed in bulk using Atomic...

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...

Twenty-one samples of deep-sea ferromanganese nodules collected from the Pacific, Atlantic, and Indian oceans were supplied by the Lamont-Doherty Geological Observatory of...

Iron-manganese crusts were chosen from existing collections in order to cover as wide an area and depth range as possible. Sampling was concentrated in the Central Pacific...

The study reported here involved the analysis of 12 rare earth and 13 minor elements in 13 nodules from the S.W. Pacific; 1 nodule from equatorial N. Pacific (DOMES Site C) as...

72 surface sediments associated with manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections...

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...

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

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

All the samples were air-dried, crushed, and ground to a fine particle size (<100 mesh). Flame analyses were carried out with a solution that was obtained by the digestion of...

Seven samples of ferromanganese nodules were analyzed using particle-induced X-ray emission technique (PIXE). All the samples were air-dried, crushed, and ground to a fine...

Thirty Mn crust samples and associated substrates were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line...
