(Table 3, page 51) Contents in uranium, thorium and proactinium for a manganese nodule from the western North Pacific retrieved during the JEDS-4 cruise of the R/V Ryofu Maru


One or two grams of dried sample were subjected to leaching by acid and the residue was separated by centrifuge.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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
