Manganese nodules and crusts from stations of the SO06 expedition (R/V Sonne) in the Aitutaki Passage have been selected for chemical analysis. Mn, Fe, Ni and Cu were analyzed...

Of the 26 samples collected during VA-05/1 cruise of R V Valdivia during 1972, 19 were nodules of different forms, 4 ferromanganese crusts and 3 cylindral nodules. Nodules and...

Ferromanganese nodules at DOMES sites A, B, and C collected by the R/V Oceanographer. Nodules selected for bulk analysis were taken from the dominant size class of each box core...

Ferromanganese nodules at DOMES sites A, B, and C collected by the R/V Oceanographer. Nodules selected for bulk analysis were taken from the dominant size class of each box core...

Initial attempts to classify the composition of manganese nodules in the Pacific Ocean illustrated the paucity of data for the Southwestern Pacific Basin. Recent major element...

The nodules examined were sampled during the R/V Valdivia cruises VA 04, 05, 09, 13/1, and 18. The majority of these samples was taken from a region extending from 135°w to...

In the mid 1970s Kennecott Exploration, Inc. conducted various systematic studies on the chemical composition of manganese nodules and crusts in order to determine the...

Fifty-seven samples of manganese nodules from the GH78-1 area were analysed in bulk rock for major and some minor metal elements to provide the data for the evaluation of the...

48 manganese nodules from the Pacific Ocean were selected by the authors for detailed analysis. "Bulk chemical composition" gives, unless otherwise indicated, the results of...

Manganese nodules and crusts were retrieved by a Continuous Line Bucket (CLB) manganese nodule retrieval system in the Clarion-Clipperton Zone (CCZ). This system was operating...

During a short geological cruise in May 1979 by HMAS Kimbla, two manganese nodules were recovered from the deep sea about 250 nautical miles southeast of Sydney. They were...

In this study, 111 manganese nodules from the north and south Central Pacific were analyzed for total sulfur and total carbon. The samples had been collected along two tracks of...

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 from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray fluorescence. Samples were ground to < 74 microns, pressed into...

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...

Manganese nodules retrieved during the BENTHIFACE expedition (R/V Melville) from the Scripps Institution of Oceanography have been analysed using X-ray emission spectroscopy...

Manganese nodules were retrieved by a Continuous Line Bucket (CLB) manganese nodule retrieval system in the Clarion-Clipperton Zone (CCZ). This system was operating from the...

Selected manganese nodules from the DEEPSONDE and BENTHIFACE expeditions conducted by the Scripps Institution of Oceanography (SIO) in the northeastern equatorial Pacific have...
