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...

X-ray emission spectroscopy (XES) was used to analyse manganese nodules and crusts from the Pacific Ocean retrieved during expeditions from the Scripps Institution of...

Manganese nodules, crusts and micronodules from dredges and cores were retrieved during campaign DM14 of R/V Dmitry Mendeleev in the Pacific Ocean. Their chemical composition...

Manganese nodules were selected from various potential mining sites of the Pacific ocean. They were dried by heating at 1000°C until total evaporation and ground to powder...

Manganese nodules were selected from various potential mining sites of the Pacific ocean. They were dried by heating at 110°C for 24 hours and ground to powder before their...

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other...

Chemical analyses were made on one hundred and forty five powder samples taken from defined parts of manganese nodules retrieved during the GH80-5 campaign of the R/V...

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

Deepsea Ventures Inc. conducted a series of assessments and tests regarding the mining of manganese nodules in the Blake Plateau area. These operations were made using the R/V...

The Blake Plateau ferromanganese samples were obtained during the USGS GOS74 Expedition in 1965. Most of them are related to a phosphorite substrate. Samples were ground and...

Mn nodule samples were decomposed with HCl and fumed with H2S04. SiO2 was estimated by the standard procedure of HF. The residue, after the removal of SiO2, was fused with...
