Available in PDF, EPUB and Kindle. Book excerpt: During the past century, scientists, world statesmen, and international entrepreneurs have become increasingly aware of the potential of the oceans as a source of minerals. This book provides an authoritative picture of the current state of marine mineral extraction. A major work of reference, it will be essential reading for both those engaged in maritime studies and for professional organisations involved in the extraction of underwater minerals.

Available in PDF, EPUB and Kindle. Book excerpt: Discoveries of new types of marine mineral occurrences during the last decade, and specifically the massive sulfide deposits at spreading ridges on the ocean floor, have significantly advanced geologic concepts about the origin of ore deposits in a very short period of time. These discoveries also renewed interest in all marine mineral occurrences including the well-known manganese nodules, and led to more wide-ranging and thorough examination of cobalt-rich manganese crusts, expanded mapping of phosphorites of continental shelves, and the initiation of several new surveys for placer minerals in shallow waters. The result of these activities is already noticeable in an increasingly broader variety of minerals being found on and below the ocean floor. This upsurge of scientific interest and research in marine minerals provided the impetus to organize an Advanced Research Workshop under auspices of the NATO Science Council and its Special Program Panel on Marine Sciences. The workshop was held in the United Kingdom at Gregynog Hall of the University of Wales, June 10-16, 1985, under the theme "Marine Minerals--Resource Assessment Strategies. " The timing of this workshop was propitious in many ways. First, marine surveys and expeditions to chart the mineral resources of the world's oceans had increased in number in recent years, involving a growing number of nations interested in obtaining firsthand information.

Download or read book Marine Mineral Exploration written by H. Kunzendorf and published by Elsevier. This book was released on 1986-05-01 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 20 years have seen extensive marine exploration work by the major industrialized countries. Studies have, in part, been concentrated on Pacific manganese nodule occurrences and on massive sulfides on mid-oceanic ridges. An international jurisdictional framework of the sea-bed mineral resources was negotiated by the United Nations Conference on the Law of the Sea (UNCLOS III). A most important outcome of this conference was the establishment of an Exclusive Economic Zone (EEZ) of at least 200 nautical miles for all coastal states and the recognition of a deep-sea regime. Mineral deposits in EEZ areas are fairly unknown; many areas need detailed mapping and mineral exploration, and the majority of coastal or island states with large EEZ areas have little experience in exploration for marine hard minerals. This book describes the systematic steps in marine mineral exploration. Such exploration requires knowledge of mineral deposits and models of their formation, of geophysical and geochemical exploration methods, and of data evaluation and interpretation methods. These topics are described in detail by an international group of authors. A short description is also given of marine research vessels, evaluation of marine exploration examples; and an overview is provided of the jurisdictional situation after UNCLOS III.

Download or read book Delineation of Mine Sites and Potential in Different Sea Areas written by Jean-Pierre Lévy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: As the importance of the Pacific Rim as a global centre of large-scale investment, development, and trade continues to increase, so do the potential benefits that Canada and other countries could reap as a result of an increased presence in this diverse region. This book, a revised, and to a large extent new, version of The Pacific Rim: Investment, Development, and Trade (1987), integrates a broad range of current economic data concerning the Pacific Rim with some of the more important theoretical issues in the area of economic development and trade. It demonstrates the paradoxical combination of strength and fragility that characterizes the emerging integrated Pacific Rim economy and attempts to clarify the nature of the framework and constraints that face foreign investors and trading partners.
