PREVIEW:

Over the past seven years, significant advances have been made in the discovery, assessment and development of mineral deposits that naturally occur on the seabed.

The oceans and seas cover about 71 percent of the surface of the earth. About 55 percent of this vast area are deep ocean basins beyond the continental slope at water depths of more than 1,000 m (3,280 ft). The surface of the Pacific Ocean alone is twice the area of all the continents. Both, the shallow continental margins and the deep ocean basins, contain valuable mineral resources. We are still at the beginning of understanding and recognizing the true economic potential of the deep sea. However, the discovery of minerals on the seafloor and our knowledge of new sources of marine minerals have developed rapidly during recent decades, yielding significant economic findings and promising and potentially valuable additions to the world’s metal resources.
