Description:
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.).
