Detailed mapping of manganese deposits in the Kauai Channel and on the Waho Shelf adjacent to the northwest corner of Oahu is near completion. Manganese crusts and nodules are concentrated on submarine terraces between 800 and 2400 meters deep. Similarities In the geomorphology and sedimentary conditions where extensive manganese deposits are present suggest that these are primary factors controlling manganese distribution in the Hawaiian Archipelago. This information may be useful for guiding future surveys, and the technology developed for studiesiIn the Hawaiian Archipelago may have application to other areas of high topographic relief and low sediment thickness (i.e., seamounts, fracture zones, fault scarps, ridges, etc.). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.874278"! ** 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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
