Annotated record of the detailed examination of Mn deposits from MIDPAC-2a (SO33) expedition stations


The dredges described in this report were taken on the R/V Sonne during the MIDPAC 2A (SO33) expedition in July-August 1984 by the Technical University of Clausthal-Zellerfeld (TUCZ).

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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 A - pp. 1-61 of Manheim, FT & Lane-Bostwick, CM (1989). For station S033_30DK the description is found at page 203 under USGS Sequence number 017078. As it is indicated in Chapter 3, Archive Collections, the description of the samples has been done by T. H. Ling and F. T. Manheim. The description is also corroborated by the other USGS Report from Friesen, WB (1987).
