1974年法国建立了锰结核勘探与研究协会。核协会每年从总拨款2350万美元中,抽出1320万美元用于勘探工作。从1970年开始,法国学者加强了快速、廉价从事勘探工作的研究。这项工作的初期,主要是在大面积内对底沉积物按点取样,以获得结核分布密度、堆积规模和有用组分含量等准确数据。法国在太平洋开展了结核海底堆积的研究工作。在30个月内,在4750个点上采了样,面积达250万平方公里,
In 1974, France established the manganese nodule exploration and research association. The Nuclear Association extracts 13.2 million U.S. dollars from the total appropriation of 23.5 million U.S. dollars each year for exploration work. Since 1970, French scholars have intensified their research on exploratory work quickly and cheaply. At the beginning of this work, we mainly sampled bottom sediments in large areas to obtain accurate data such as the distribution density of tuberculosis, the scale of accumulation, and the content of useful components. France has conducted research on the seafloor accumulation of nodules in the Pacific Ocean. Within 30 months, a sample of 4,750 points was taken, covering an area of 2.5 million square kilometers.
