Abstract:
The table presents the REE contents and fluxes of manganese nodules and crusts from the Manganese Nodule Program (MANOP) site H (6.5° N, 93° W) in the eastern equatorial Pacific. Samples for this study were analysed for La, Ce, Nd, Sm, Eu, Tb, Yb and Lu by instrumental neutron activation. Analytical precision for the REE was within 10% for all samples, except for Nd and Tb which have peak interferences. Interferences due to U were negligible.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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 Table 1, pp. 445 of the related publication.
