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.

This volume discusses environmental issues associated with deep-sea mining, with an emphasis on potential impacts, their consequences and the policy perspectives. The book describes the methods and technologies to assess, monitor and mitigate mining impacts on marine environments, and also suggests various approaches for environmental management when conducting deep-sea mining. The volume brings together information and data for researchers, contractors, mining companies, regulators, and NGOs working in the field of deep-sea mining. Section 1 highlights the various environmental issues and discusses methods and approaches that can help in developing environmentally sustainable deep-sea mining. Section 2 details the results and outcomes of studies related to impact assessment of deep-sea mining, and proposes methods for monitoring. Section 3 discusses the need and means for developing data standards and their application to deep-sea mining. Section 4 discusses the policies, approaches, and practices related to deep-sea mining, suggests formats for developing environmental impact statements (EIS) and environmental management plans (EMP), and describes national and international regulations for environmental management. Section 5 concludes the text by putting deep-sea economic activities into an environmental context and conducting techno-economic analyses of deep-sea mining and processing.

The book includes a synthesis of research findings on the structure and evolution of the Central Indian Ocean Basin and its ferromanganese deposits, in particular, on the exploration campaign since 1980s. A comprehensive mixture of recent studies along with classical theories starting from the 1960s is the hallmark of the book. Recent concepts and hypotheses, and also critical appreciation of the state-of-the-art knowledge on nodule formation and resource management are incorporated. After limiting the geographical extension of the nodule field and describing its physiographic, geological, biological, physical and chemical characteristics in chapter 1, the various structural, tectonic and volcanic elements are described in chapters 2 and 3. The bottom sediment characteristics that floor the nodules and crusts are dealt with in chapter 4. The nodules and crusts are described in detail in chapter 5, and their process of formation in the light of variable source material, local and regional tectonic activities, and midplate secondary volcanisms are discussed. The mining, environment, metallurgy, legal and economic aspects of the nodule resources are discussed in chapter 6. This title fulfils the growing need to bring voluminous, but scattered information in the form of a book for easy dissemination to students and researchers.* First dedicated book on the Indian Ocean manganese nodule resources * Comprehensively discusses the dynamics of nodule formation in the Indian Ocean Nodule Field (IONF) * Independently assesses the influence of tectonics and volcanism on the manganese nodule resource potential in local and regional scales

Environmental information is important for successful planning and execution of naval operations. A thorough understanding of environmental variability greatly increases the likelihood of mission success. To ensure that naval forces have the most up-to-date capabilities, the Office of Naval Research (ONR) has an extensive environmental research program. This research, to be of greatest use to the warfighter, needs to be directed towards assisting and solving battlefield problems. To increase research community understanding of the operational demands placed on naval operators and to facilitate discussion between these two groups, the National Research Council's (NRC) Ocean Studies Board (OSB), working with ONR and the Office of the Oceanographer of the Navy, convened five previous symposia on tactical oceanography. Oceanography and Mine Warfare examines the following issues: (1) how environmental data are used in current mine warfare doctrine, (2) current procedures for in situ collection of data, (3) the present capabilities of the Navy's oceanographic community to provide supporting information for mine warfare operations, and (4) the ability of oceanographic research and technology developments to enhance current mine warfare capabilities. This report primarily concentrates on the importance of oceanographic data for mine countermeasures.

'Deep-Sea Sediments' focuses on the sedimentary processes operating within the various modern and ancient deep-sea environments. The chapters track the way of sedimentary particles from continental erosion or production in the marine realm, to transport into the deep sea, to final deposition on the sea floor.
