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,...

Silicon, aluminum, calcium, titanium and iron percentages were obtained by X-ray fluorescence analysis using an EDAX International EXAM system. Sediment samples collected during...

From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other...

Four manganese nodules collected south and southwest of Rarotonga one of the Cook Islands were subjected to microprobe analysis in order to determine variations in chemical...

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...

Five manganese nodules from a range of deep-sea and fossil environments were selected for this study. Most samples were prepared for bulk analysis by grinding the material...

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...

During a research cruise of the New Zealand research vessel Tangaroa 1974 large manganese nodule fields with high density have been discovered in the Southwest Pacific. The...

A reconnaissance cruise by the NZOI research vessel TANGAROA has defined limits of manganese nodule occurrence in portions of the Southwestern Pacific Basin. Bottom samples were...
