Chemical analyses of Fe-Mn nodules from the Indian Ocean
Ten manganese nodules from the Northeast Pacific Ocean have been sampled from box cores retrieved during R/V Valdivia campaign V13/1. Cross-sections for each of the nodules have... -
Chemical composition of manganese nodules and crusts from the Bauer Basin, Pa...
Samples were collected from R/V "Yaquina" during cruise YALOC-73 of Oregon State University. The six Mn nodules and four Mn crusts from Y73-3-22D station in the Bauer Basin were... -
Chemical composition of Pacific and Indian ocean manganese nodules and crusts...
Manganese nodules and crusts from the Pacific and Idian oceans were analyzed at Scripps Institution of Oceanography using atomic absorption spectrophotometry (AAS). Samples were... -
Chemical analysis of manganese nodules and crusts from the Romanche trench ar...
Manganese nodules and manganese crusts covering basalt or volcanic breccia rocks have been analysed using various methods. Energy dispersive X-Ray analysis (EDAX)was used for... -
Accumation rates of manganese in manganese nodules using total alpha activity
The manganese content of 4 manganese nodules was determined by atomic absorption. The decrease of total alpha activity was used to evaluate Mn accumulation. Because CaCO3 is a... -
Kennecott Standard GRLD-126 manganese nodule replicate Atomic absorption spec...
The Kennecott nodule standard GRLD-126 was run with several batches of the nodule structure zone samples in order to check the precision of the atomic absorption analyses. Using... -
Chemical composition of selected manganese nodule and ferromanganese crust st...
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... -
Bulk chemical composition of Southwestern Pacific Ocean manganese nodules (Ex...
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,... -
Chemical composition of Southwestern Pacific Ocean surface sediments (Expedit...
Silicon, aluminum, calcium, titanium and iron percentages were obtained by X-ray fluorescence analysis using an EDAX International EXAM system. Sediment samples collected during... -

During the evaluation of marine mineral resources of the Samoan region sponsored by CCOP/SOPAC program (ESCAP, United Nations) the R/V Machias successfully retrieved a number of... -
Chemical composition of manganese crusts fom the Southwest Pacific Ocean
During cruise L582SP of R/V Lee from USGS, dredges performed on the Tonga ridge have retrieved manganese crusts deposited on sandstone formations. These samples have been... -
Chemical composition of manganese nodules from GH80-1 cruise
67 samples of manganese nodules were obtained during the GH79-1 Cruise of R/V Hakurei Maru in the northern part of the Central Pacific Basin. All nodules were immersed in... -
Chemical composition of manganese nodules from GH80-1 cruise
Manganiferous materials were collected at 49 stations in the Central Pacific Basin, the Mid-Pacific Mountains, the Manihiki Plateau, and the Penrhyn Basin during cruise GH80-1.... -
Chemical composition of sediments from GH80-1 cruise
The moisture content and the minor element contents were determined for 115 sediment samples collected from the G H 80-1 survey traverses of the Central Pacific Wake-Tahiti... -
Bulk chemical analysis of manganese crusts from the Equatorial Pacific Ocean
Ferromanganese crusts were selected from two cruises performed by R/V Moana Wave in early 1986 and 1987 within territorial waters of the Cook Islands, Kiribati, Tuvalu and... -
Chemical analysis of manganese deposits retrieved during Manganese Nodule Pro...
Manganese nodules and crusts were taken from free-fall grabs at various stations of the Manganese Nodule Program BOMDROP cruise MN75-03. They were analysed using atomic... -
Trace metal levels in selected ferro-manganese crusts from the Pacific Ocean
Chemical assessment of trace metals concentrations in a selected set of manganese crusts and coatings from the Pacific Ocean. Composition has been determined by atomic... -
Bulk chemical analysis of selected manganese nodules retrieved during VA13/2 ...
Manganese nodules from VA13/2 cruise (R/V Valdivia) were selected for a variety of morphologies and size. They were regrouped by size class and chemically analyzed in bulk. Mn,... -
Carbonate-free basis chemical composition of sediments from the Bauer Deep
Sediment cores of the Bauer Deep were obtained by standard piston-coring techniques on cruises of the R/V Atlantis II (no. 54) and R/V Chain (no. 100) of the Woods Hole... -
