(Table 2, page 71) Major elements geochemistry of manganese nodules and ferromanganese crusts from the Pacific Ocean, samples dried at 110°C for 24 hours and autoclaved at 200°C and 180 bars

DOI

The samples were wet-ground to powders and kept in artificial seawater. After drying samples were dissolved in 15ml of I:2HCl+1:5NH3OHCl at 75°C for chemical analysis by atomic absorption spectrometry.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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
