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...

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...

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...

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 sediment samples were collected in the Central and South-West Pacific ocean during R/V Sonne campaign SO06 as part of the I.C.I.M.E. (International...

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...

Manganese nodules were retrieved from the Pacific Ocean during the CNEXO-NIXO campaign and the GH76 and GH80 campaigns of the R/V Hakurei-Maru. Their chemical composition was...

Manganese nodules from expeditions conducted by the Scripps Institution of Oceanography (SIO) in the Clarion-Clipperton Fracture Zone (CCZ) in the Pacific Ocean have been...

Manganese nodules were retrieved during cruises of the Scripps Oceanographic Institution (SIO). Their chemical composition was determined using X-ray fluorescence. From 1983...

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...

103 nodule samples from each station of the GH81-4 survey from R/V Hakurei Maru were split; one half for microscopy on polished sections and one half for X-ray diffraction (XRD)...

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...

The samples studied have been taken from the Central Pacific area during the research cruise Midpac '81. Metal concentration was determined by Atomic Absorption Spectrophometry...
