Abstract:
The data presented in this report is the result of investigations carried out by a number of laboratories on a suite of rocks dredged from the Mid - Atlantic Ridge at 45°N by F. Aura en to and K. S. Manchester during the three Bedford Institute cruises BI 19-66 Hudson, BI 22-68 Hudson, and BI 23-68 Theta.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
