This handbook summarizes the main advances in our understanding of marine minerals and concentrates on the deposits of proven economic potential. In cases where our knowledge may be too limited to allow defining of their economic potential, those minerals are covered regionally or by deposit type. Handbook of Marine Mineral Deposits is divided into three sections; Marine placers, manganese nodules and crusts, and deep-sea hydrothermal mineralization. All of these mineral deposits have great potential importance to economic geologists and marine mines. Edited by an acknowledged expert in the field, this handbook includes work by internationally renowned contributors. The new United Nations Law of the Sea, ratified by over 100 countries within the past two years, provides a framework and guidelines for deep-sea mineral exploration that increases international interest in this book. The Handbook serves as a platform from which to launch the more detailed evaluation studies that will need to take place in the 21st century before recovery can continue or commence. Handbook of Marine Mineral Deposits is useful to mineralogists, economic geologists, marine geologists, marine miners, and conservationists. Features

Intertidal Deposits: River Mouths, Tidal Flats, and Coastal Lagoons combines the authors personal and professional experience with the mass of available literature to present a cohesive overview of intertidal deposits and the widely diverse conditions of their formation worldwide. This includes the strong influence of water movements, climate, sediment particle characteristics, vegetation, fauna, and man. Intertidal areas are important for many reasons both scientifically and economically and recently, a growing concern for conservation of these fragile regions strives to preserve and protect their natural balance. This book, written by an international expert in the field, concentrates on the more important intertidal areas distinguished by size and morphology, tidal range, the degree and type of vegetational cover, the amount and type of benthic fauna, the extent of human exploitation, and the degree of previous study.

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Exploring the potential use of bivalves as indicators and monitors of ecosystem health, this book describes live and computer simulated experiments, mesocosm studies, and field manipulation experiments. This second edition discusses major new developments, including phase shifts in many coastal and estuarine ecosystems dominated by suspension-feeding bivalves, the invasion or introduction of alien bivalve species, the rapid growth of environmental restoration focused on bivalves, and the examination of geological history with regard to global climate change and its impact on bivalve-dominated systems.

This new Encyclopedia of Coastal Science stands as the latest authoritative source in the field of coastal studies, making it the standard reference work for specialists and the interested lay person. Unique in its interdisciplinary approach. This Encyclopedia features contributions by 245 well-known international specialists in their respective fields and is abundantly illustrated with line-drawings and photographs. Not only does this volume offer an extensive number of entries, it also includes various appendices, an illustrated glossary of coastal morphology and extensive bibliographic listings.

Pollution of estuaries and coastal marine waters is of profound ecological and societal importance. These coastal environments serve as critical habitat for a multitude of organisms and are of great commercial and recreational value to humans. Designed to meet the research, monitoring, and assessment needs of scientists, administrators, planners, and managers, Pollution Impacts on Marine Biotic Communities is a uniquely comprehensive reference covering pollution in coastal marine and estuarine waters. The book provides a detailed look at the short- and long-term impacts of pollutants on these ecologically important regions. Case studies that reflect a broad range of pollution problems are analyzed, outlining the real-life issues and providing solutions to common problems. Despite being highly sensitive systems, estuarine and coastal marine environments have served as repositories for dredge spoils, sewage sludge, and industrial and municipal effluents for many decades. The adverse effects of these pollutants are only now being fully realized and understood. Pollution Impacts on Marine Biotic Communities includes a basic introduction to the subject of pollution in estuarine and marine environments and also a detailed examination of specific marine pollutants. Both the coverage and the format - which includes abundant illustrations and tables - make this book a valuable reference for scientists, administrators, and students engaged in coastal research and planning.

This is the first book to provide a detailed treatment of the field of larval ecology. The 13 chapters use state-of-the-art reviews and critiques of nearly all of the major topics in this diverse and rapidly growing field. Topics include: patterns of larval diversity, reproductive energetics, spawning ecology, life history theory, larval feeding and nutrition, larval mortality, behavior and locomotion, larval transport, dispersal, population genetics, recruitment dynamics and larval evolution. Written by the leading new scientists in the field, chapters define the current state of larval ecology and outline the important questions for future research.

Raw materials have been essential in the development of all human societies through history and moving into a greener, more carbon-lean future we become increasingly reliant on access to a growing number of raw materials. Minerals for new technologies improving the quality of our lives and the environment are the building blocks of the new Green Stone Age. This Special Publication presents ongoing research and mapping programmes focusing on minerals needed for the transformation to greener societies. In addition to new exploration models and shared geological information on the different prospective currently mined areas, the notion of criticality in different countries is discussed and examples of ongoing national and cross-country research and mapping programmes are presented. In addition to the resource/reserve and technical-economic aspects, the social and environmental dimensions are also a focus in some of the contributions, as holistic approaches to the exploration and exploitation of critical minerals and materials are needed to fulfil the green transition and goals for the Green Stone Age.
