Chemical composition of manganese nodules from the Pacific and Atlantic Ocean using X-ray Emission Analysis (XES)


Manganese nodules from the East Pacific Ocean were analyzed at Scripps Institution of Oceanography after being ground to < 74 Microns, pressed into pellets, dried at 110 °C and analyzed by XES for 1000 seconds.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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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 propriatory 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.
