Abstract:
Testing of a continuous bucket-line dredging system was carried out in the South Pacific August 23 through September 14, 1970 by Japan Resources Association aboard the vessel "Chiyoda Maru No. 2". Fifteen dredge stations were occupied, and the system was tested at depths of 1080, 3755, and 1220 meters. The system is designed to recover manganese nodules, and the tests helped to verify its feasibility. A brief discussion of the merits of the continuous bucket-line compared to other continuous systems is made.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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