Samples were collected from R/V "Yaquina" during cruise YALOC-73 of Oregon State University. The six Mn nodules and four Mn crusts from Y73-3-22D station in the Bauer Basin were analyzed both chemically and mineralogically. One cross-section through each sample was ground in an agate mortar, dissolved with hydrofluoric acid and aqua regio under pressure, and analyzed by atomic absorption spectrophotometry for Fe, Mn, Cu, Ni, Zn, Co, Ba, Ca, Si, and Al.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.This dataset represents the digitized Table 2, pp. 59 of the related publication.
