Abstract:
103 nodule samples from each station of the GH81-4 survey from R/V Hakurei Maru were split; one half for microscopy on polished sections and one half for X-ray diffraction (XRD) and chemical analyses. The latter half was powdered in air and subjected to XRD analysis. The powder samples were analyzed for Mn, Fe, Cu, Ni, Co, Pb, Zn, Si, and A1 by atomic absorption spectroscopy after borate/carbonate fusion and HC1 dissolution. All concentrations were shown at ll0 C dried base after measurement of water contents (H20-) and LOI (H20+).

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
This dataset represents the digitized Appendix 1 - Part 1, pp. 260-271 of the related publication.
