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...

Manganese nodules were retrieved during the SO06 (R/V Sonne) and COPANO (R/V Le Suroit) campaigns as part of the international "Hawaii-Tahiti Transect Program" initiated at the...

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...
