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.本报告所记载的水下摄影资料与箱式岩芯样品，采集自1975年6月执行RP-6-OC-75航次的"海洋学家号"（R/V Oceanographer）研究船，作业区域为DOMES项目（深海采矿环境研究，Deep Ocean Mining Environmental Study）的C海区。 DOMES项目的第一阶段由美国地质调查局（U.S. Geological Survey）在美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）的支持下开展。 该项目的核心目标是，在商业化深海锰结核采矿作业启动前，获取必要信息以对深海锰结核采矿对海洋生态系统的影响开展及时且独立的评估。 本项目由学界与矿业界协作发起。 整个研究分为两个阶段：首先获取深海环境的基础数据，随后评估原型采矿作业对该环境的影响。
