Annotated record of the detailed examination of Mn deposits from R/V Oceanographer Cruise RP-6-OC-75 in the DOMES, Site C area

Submarine photography and box cores described in this report were taken during the R/V Oceanographer Cruise RP-6-OC-75 in June 1975 over Area C of the DOMES project (Deep Ocean Mining Environmental Study). This Phase I of the DOMES project was conducted by the U.S. Geological Survey under the auspices of the National Oceanic and Atmospheric Administration (NOAA). The purpose of DOMES project was to acquire the information necessary to provide both a timely and an independent assessment of the impact of deep ocean manganese nodule mining on the marine ecosystem before commercial mining operations begin. It was formulated in cooperation with the academic community and the mining industry. It consisted of a two-phase study, first to obtain basic information on the deep ocean environment and then to assess the impact of prototype mining operations on that environment.
