Comment:

118 samples of manganese nodules obtained during the GH77-1 cruise were analyzed in bulk rock for major and some minor metal elements to provide the data for the evaluation of the chemical features of the nodules. Basing on these analytical data, the authors discuss briefly the relationship between the metal contents and the manganese nodule types, the relationship between each metal element, and the correlation between the nodule abundance and Cu and Ni grade.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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