| contents | Occurrences and associations of ferro-manganese deposits at relatively shallow depths in the Hawaiian Archipelago were revealed by a series of cruises on the R/V Teritu. The deposits are accreting principally on the three prominent terrace levels around all of the Islands-at 400 to 800 meters, 1200 to 1600 meters, and 2400 meters as crusts and pavements. In some instances, examples of deposits at low depth demonstrate the rapid growth of ferro-manganese oxides and the importance of seed material for manganese coating to grow on artificial seeds. A large number of iron and steel samples encrusted with ferromanganese deposits have been collected by divers during the past year off Oahu beaches. |
