The Indian Ocean Nodule Field

The Indian Ocean Nodule Field: Geology and Resource Potential, Second Edition, provides a view of the most recent studies along with classical theories starting from the 1960s. New concepts, hypotheses and critical appreciation of the state-of-the-art knowledge on nodule formation and resource management are featured in this new edition. The economy of the Indian Ocean has vast potential and yet it is one of the least studied oceans. Garnering economic advantage out of mineral resources from deep oceans has been a long cherished dream for the mining community. The availability of 5-metal rich polymetallic (manganese) nodules in specific areas of the Indian Ocean has lured researchers to discover more about their processes of formation, growth, distribution and enrichment. Collates, discusses and succinctly presents voluminous and scattered information from various books and journals for easy understanding and dissemination Features two new chapters: statistical modeling of the formation, growth, distribution and metal enrichment of nodules; and biogeochemistry of the Central Indian Ocean Basin Includes an assessment of Indian Ocean nodules, one of the least studied oceans in comparison to samples analyzed from the world’s oceans

The most comprehensive assessment on Indian Ocean manganese nodule formational processes in one source.

The economic paradigms currently dominating the world are not sustainable. The threats from climate change, exploitation-based approaches to commerce, and the excess acquisition of resources loom large as well as the possibility of military flare-ups. Maintaining a balance between development and ecosystems, aspirations for growth, and the need for sustainability is a prescient challenge. The Indian Ocean Region (IOR) encompasses some of the poorest countries in the world and those that will bear the brunt of the negative impacts from climate change. This book explores the immense potential of the IOR and how best to maintain sustainable and responsible economic and strategic activities. The combination of science, innovation, and entrepreneurship will create a new blue economy business model, which has the potential to transform society. Based on critical analysis of the model and its practical applications, including risks as well as opportunities, the topics discussed range from food security, energy, and resilience to climate change, trade and investments, and improved maritime connectivity to tourism, poverty alleviation, and socioeconomic growth, encompassing a wide range of interests and expertise. FEATURES Examines the geo-politics, geo-resources, and geo-hazards of the IOR and identifies opportunities and methods to achieve success Covers a detailed assessment of available resources (fisheries, minerals, energy), threats such as pollution (plastic, acoustic, carbon, bio-invasion), geo-politics (maritime security, military invasion), and strategic vision (determining carrying capacity, ethical governance, and responsible ecosystem) of the Indian Ocean Analyzes the economics of the blue economy, the global scenario including the Pacific and Caribbean islands, and the aspect of the Chinese geo-political invasion in the Indian Ocean Inspires entrepreneurs to adopt new ways of creating economic benefits, reducing energy use, and increasing revenue while simultaneously helping the communities involved Discusses the threat and security perspectives of the IOR and the collective responsibility for a sustainable use of resources Crossing a wide range of interests and expertise, this book explores topics and ideas that will be essential to researchers and professionals in marine sciences, economics, business, geography, and political sciences. Graduate students in the same fields as well as any and all organizations that maintain a presence in the IOR will likewise find this book to be a valuable resource.

The current scenario provides an ideal opportunity to confer higher priority to the marine resources of the Indian Ocean, particularly in terms of integrated management of the deep sea, shallow sea and coastal resources. This will maximize their potential in the sustainable development goal (SDG) pattern, leading to an appropriate environmental management. Therefore, this book aims to provide an overview of the area and to highlight the potential market opportunities represented by this vast and rapidly developing nation. In doing so the following aspects have been covered: Exclusive title focussing on mineral resources of Indian ocean. Discusses living, nonliving, ocean waves and tidal energy, ocean environment and protection aspects. Includes information on key themes, details of organizations associated with the Indian Ocean. Illustrates deep sea mining technology and environmental perspectives. Covers hydrocarbons-sub sea oil and gas, minerals from placer deposits to deep sea nodules, sea floor massive sulphides and cobalt rich encrustations.

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.

Manganese nodules were first discovered on the ocean floor 160 miles south-west of the Canary Islands on February 18, 1803, during the first complex oceano logical cruise of the Challenger. They surprised researchers by their unusual shape and also by their unusual chemical composition; nevertheless for many years after wards, they were considered merely as one of Nature's exotic marine tricks. After the Secpnd World War, a comprehensive investigation of the World Ocean started, and new data were obtained on a wide distribution of manganese nodules and their polymetallic composition, that made scientists consider nodules as one of the major characteristics of the deep oceanic zone. Recently, meaning since the 1960's, nodules have been recognized as a potential ore source, investigation of which is stimulated by the progressive depletion of land-based mineral resources. Several generations of scientists from various countries have contributed to the problem of exploration of manganese nodules on the ocean floor. Though the problem has been posed, it has not been solved yet because it required, in its turn, a scrutiny of some fundamental aspects such as composition, nature, accretion r'ate of nodules and retrieval of nodule fields. These problems have been discussed in thousands of papers and larger publications; see, in particulare, Mero, 1965; Horn, 1972; Morgenstein, 1973; Bezrukov, 1976; Glasby, 1977; Bischoff and Piper, 1979; Lalou, 1979; Manganese nodules, 1979; Varentsov, 1980; Cronan, 1980; Manganese nodules . . . , 1984, 1986.

A global blue economy is an economic arena that depends on the benefits and values realized from the coastal and marine environments. This book explains the "sustainable blue economy" as a marine-based economy that provides social and economic benefits for current and future generations. It restores, protects, and maintains the diversity, productivity, and resilience of marine ecosystems, and is based on clean technologies, renewable energy, and circular material flows.
