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...

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

If nodules were chemically homogeneous objects, their bulk compositions would paint a complete picture. But they are not, as can be assumed simply from visual recognition of...

The bulk compositions of Samoan Basin nodules were determined for this study, and these data have been compiled with those of Glasby, et al. (1975) to form Appendix L. Silicon,...

Mn nodule shapes which can be described as spheroidal, ellipsoidal or polynucleate predominate in the Southwestern Pacific Ocean. The morphology, size, weight and number of...

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...

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...

A geochemical (major and trace elements including rare earths) study was made of core samples drilled between the Touamotou Archipelago and the Marqueses Islands during the...

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...

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...

Local variability of manganese nodule facies and associated sediments were studied around abyssal hills (60 x 60 km²) located in the equatorial zone of the Central Pacific...

Nodule samples obtained were described and studied on board for 1) observation of occurrence and morphology in and outside samplers, size classification, measurement of weight...

In the nodule field of the Peru Basin, situated south of the zone of high bioproductivity, a relatively high flux of biogenic matter explains a distinct redox boundary at about...
