Abstract:
The cores and dredges described in this report were taken on the GH74-5 Expedition in September-October, 1974 by the Geological Survey of Japan from the R/V Hakurei Maru. A total of 36 cores, dredges and submarine camera sites have been visited. The survey conducted an investigation of the manganese deposits in the Eastern Pacific Basin and the East of the Okinawa islands

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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