海底锰瘤的开采,为通过环境的障碍,美国NOAA进行深海开采研究,其研究项目与早期1978年的报告没有大的变化,认为解决环境问题是发展深海锰瘤工业化的关键,经过五年试验,花费超过五百万美元,提出了锰瘤开采对海上环境、 The exploitation of submarine manganese nodules has led to the study of deep sea exploitation by the United States NOAA through environmental barriers. There have been no major changes in its research projects and reports from the early 1978, and it is believed that solving environmental problems is the key to the development of industrialization of deep-sea manganese nodules. After five years of trials, , spent more than five million U.S. dollars, proposed manganese mining for the marine environment,
