Oceans have been the subject of scientific inquiry for hundreds of years, but significant study of mineral occurrences on the deep ocean floor has only begun to take place. Man's present knowledge of the ocean floor had to await the development of sophisticated research equipment capable of probing the ocean to great depths. This began in the 1940's and since then the accelerated pace of ocean research has generated a large amount of data on the ocean environment - mostly through the work of academic and governmental scientific organizations around the globe. These new scientific disclosures confirmed the wide-spread occurrence of metal-bearing lumps on the deep ocean floor that hold great promise as an important new source of raw material. Encouraged by these events, several groups of private, semi-private, and public enterprises became active; a transition occurred from scientific interest in the metal-bearing lumps to commercial interest. But these pioneer developers faced a formidable task. Information about the minerals and their environment of deposition was inadequate; technology for mining them continuously was non-existent and very little was known about the adaptability of processing technologies for land-based ores to these minerals.

Prospecting and exploration for manganese nodules has, as its ultimate objective, the discovery and delineation of an area of the ocean floor with reserves of sufficient quantity and quality to support a mining operation under existing economic, technical and political conditions. While prospecting concentrates primari lyon the collection of geological information, an exploration programme includes other activities that relate to the develop ment of technology, financial analysis of the prospect and environmental protection. Such work on a deposit in turn leads to the development of a mine-site. The mine-site concept brings together information in a way that recognizes the interplay among a number of dynamic factors which must satisfy a set of technical and economic conditions. Defining a mine-site, therefore, is a process of accounting for those factors. Throughout the years of meetings of the Third United Nations Conference on the Law of the Sea, many questions arose about ocean mine-sites. Two related topics in particular received attention: the total number of available mine-sites, and the amount of area necessary for a mining operation. Both of these topics have been subject to a great deal of speculation, and even with the best available information, there remains a degree of uncertainty that arises from both incomplete knowledge and natural variability in the seabed and the resource, and different technology and production objectives. For example, estimates of the size of the area necessary for an ocean mine-site vary even when made by the same company.

This comprehensive book contains contributions from specialists who provide a complete status update along with outstanding issues encompassing different topics related to deep-sea mining. Interest in exploration and exploitation of deep-sea minerals is seeing a revival due to diminishing grades and increasing costs of processing of terrestrial minerals as well as availability of several strategic metals in seabed mineral resources; it therefore becomes imperative to take stock of various issues related to deep-sea mining. The authors are experienced scientists and engineers from around the globe developing advanced technologies for mining and metallurgical extraction as well as performing deep sea exploration for several decades. They invite readers to learn about the resource potential of different deep-sea minerals, design considerations and development of mining systems, and the potential environmental impacts of mining in international waters.
