The cores and dredges described at this site were taken on the INDUSOM cruise from 17 to 30 April 1985 by the Muséum National d'Histoire Naturelle from the R/V Marion Dufresne. A total of 22 cores were recovered and are available at MNHN for sampling and study.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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