60年代初,科学家们对深海海底矿物资源极为关注,并以美国为中心着手勘查与开发,之后日本也进行了此项工作。70年代对锰核的勘查盛行,至80年代,海底热液矿床、钴富壳等作为新的海底矿物资源备受青睐。然而对于海底矿物资源的利用则存在技术、政治和经济三大问题。
In the early 1960s, scientists paid great attention to deep-sea seabed mineral resources and started the exploration and development centered on the United States. Japan later conducted this work. In the 1970s, the exploration of manganese nucleus was prevalent. By the 1980s, the seabed hydrothermal deposits and cobalt-rich crusts were favored as the new seabed mineral resources. However, there are three major technical, political and economic issues regarding the utilization of seabed mineral resources.
