PANGAEA, https://doi.org/10.1594/PANGAEA.854407, Supplement to: MNHN (1975): NOSICAA Cruise - MD06, R/V Marion Dufresne, Core list. Muséum National d'Histoire Naturelle, Paris, unpublished, https://www.pangaea.de/expeditions/events/MD06 Abstract: The cores and dredges described at this site were taken on the NOSICAA cruise from 28 May until 5 July 1975 by the Muséum National d'Histoire Naturelle from the R/V Marion Dufresne. A total of 36 cores and dredges were recovered and are available at MNHN for sampling and study.

Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
