Abstract:
Ferromanganese crusts were selected from two cruises performed by R/V Moana Wave in early 1986 and 1987 within territorial waters of the Cook Islands, Kiribati, Tuvalu and Western Samoa, in the south equatorial Pacific. Chemical analyses were performed on a 1l0°C dry basis. Triplicate splits were dissolved with mineral acids in Parr bombs. Solutions were analyzed for selected major and minor constituents by atomic absorption (AA). The relative precision of analyses was better than 7% of the reported value; accuracy of determinations was ascertained by analysis of U.S. Geological Survey (USGS) standard Fe-Mn nodules A-1 and P-1; results were generally within 5% relative to recommended values.

Comment:
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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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 Appendix II, pp. 453, of the related publication.
