In the Pacific, potentially ore-grade nodules are generally confined to two zones running roughly east–west in the tropical regions, which are well separated in the eastern Pacific but which converge at about 170°–180°W (Figure 5).They follow the isolines of intermediate biological productivity, strongly suggestive of a biological control on their distribution.
