Abstract:
Deepsea Ventures Inc. conducted a series of assessments and tests regarding the mining of manganese nodules in the Blake Plateau area. These operations were made using the R/V Prospector from 1969 until 1971. Retrieved samples were analysed using Atomic Absorption Spectrometry.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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 2b, pp. 28 of the related publication.
