The Midpac '81 (SO18) exploration voyage with the R/V Sonne was a first step to study the regional distribution, nature and formation of Co-rich manganese crusts over submarine...

The dredges, free-fall grabs, cores and camera sled photographies described in this report were taken during the Midpac '81 expedition with RV Sonne (SO 18) in the Pacific...

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...

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...

The data encoded in the Scripps Institute of Oceanography Nodule Data Bank (SNDB) was used as a model for the publication of USGS Ferromanganese Crusts Data Bank. The chemical...

During the evaluation of marine mineral resources of the Kiribati region sponsored by CCOP/SOPAC program (ESCAP, United Nations) various cruises of the R/V Machias successfully...

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...

The composition of the acid-insoluble residue and hydrolysate fraction has been determined for manganese crusts and coatings retrieved along an equatorial Pacific transect...

The composition of the acid-insoluble residue and hydrolysate fraction has been determined for manganese nodules retrieved along an equatorial Pacific transect surveyed during...

During the TRANSINDIK (VA07) campaign of the R/V Valdivia in the Central Indian Ocean manganese nodules were retrieved and analysed for their metal composition at Preuss-AG...

In 1978 during cruise CK-78(2) of the R/V Machias scattered manganese nodules were recovered from three stations in the Samoa Basin and abundant nodules from five stations in...

Manganese nodules have been shown to consist of heterogeneous mixtures of a variety of biogenic, detrital and authigenic particles in a finely laminated structure. On a...

Bulk chemical analyses of manganese nodules retrieved during the R.V. Tangaroa cruise of May-June 1976. The nodules occur on silty clay. Approximately two-thirds are either...

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...

61 manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections at the University of Hawaii,...

5 manganese nodules from 2 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray fluorescence. Samples were ground to < 74 microns,...

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