Abstract:
During Cruise VA 04/2 of the R. V. Valdivia in 1972, numerous samples were collected of manganese nodules, sodiments, and the pore water of the Sediments in the area betwoen 6° N and 11° N and between 149° W and 154° W in the Central Pacific. This paper reports on the geochemical study of 70 manganese nodules from 12 stations (box-core and dredge samples). The nodules Irom a single Station vary considerably in diemical composition. These variations are of the same magnitude as the variations in nodule composition over the entire survey area. The ratios of manganese to nickel, copper, and zinc show good positive correlation as do the ratios of iron to lead and, to a lesser extent, of iron to cobalt. No correlation was found between the environment of the manganese nodules and their metal content. Three internal zones, the outer. intermediate, and core zones, of some nodules were studied in detail. Trends of differences of Chemical composition from surface to core were found for numerous elements and elemental ratios.

Comment:
From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.
