A great utility to the international oceanographic, climate research, and operational communities. This volume provides a global analysis of oceanographic data focusing on oxygen. Contains maps of dissolved oxygen, oxygen saturation, and Apparent Oxygen Utilization at selected standard levels of the world ocean on a one -degree grid. Basin zonal averages and basin volume averages are computed from objectively analyzed fields and are presented in the form of figures and tables.

Describes the ocean biome, including climate, geology, geography and biodiversity.

Marine and coastal applications of GIS are finally gaining wide acceptance in scientific as well as GIS communities, and cover the fields of deep sea geology, chemistry and biology, and coastal geology, biology, engineering and resource management. Comprising rigorous contributions from a group of leading scholars in marine and coastal GIS, this book will inspire and stimulate continued research in this important new application domain. Launched as a project to mark the UN International Year of the Ocean (1998) and supported by the International Geographical Union's Commission on Coastal Systems, this book covers progress and research in the marine and coastal realms, in the areas of theory, applications and empirical results. It is the first book of its kind to address basic and applied scientific problems in deep sea and coastal science using GIS and remote sensing technologies. It is designed for GIS and remote sensing specialists, but also for those with an interest in oceans, lakes and shores. Coverage ranges from seafloor spreading centres to Exclusive Economic Zones to microscale coastal habitats; and techniques include submersibles, computer modelling, image display, 3-D temporal data visualization, and development and application of new algorithms and spatial data structures. It illustrates the broad usage of GIS, image processing, and computer modelling in deep sea and coastal environments, and also addresses important institutional issues arising out of the use of these technologies.

Marine environmental history analyses the changing relationships between human societies and marine natural resources over time. This is the first book which deals in a systematic way with the theoretical backgrounds of this discipline. Major theories and methods are introduced by leading scholars of the field. The book seeks to encapsulate some of the major novelties of this fascinating new discipline and its contribution to the management, conservation and restoration of marine and coastal ecosystems as well as the cultural heritages of coastal communities in different parts of the world.

Underwater acoustic digital signal processing and communications is an area of applied research that has witnessed major advances over the past decade. Rapid developments in this area were made possible by the use of powerful digital signal processors (DSPs) whose speed, computational power and portability allowed efficient implementation of complex signal processing algorithms and experimental demonstration of their performance in a variety of underwater environments. The early results served as a motivation for the development of new and improved signal processing methods for underwater applications, which today range from classical of autonomous underwater vehicles and sonar signal processing, to remote control underwater wireless communications. This book presents the diverse areas of underwater acoustic signal processing and communication systems through a collection of contributions from prominent researchers in these areas. Their results, both new and those published over the past few years, have been assembled to provide what we hope is a comprehensive overview of the recent developments in the field. The book is intended for a general audience of researchers, engineers and students working in the areas of underwater acoustic signal processing. It requires the reader to have a basic understanding of the digital signal processing concepts. Each topic is treated from a theoretical perspective, followed by practical implementation details. We hope that the book can serve both as a study text and an academic reference.

The Indian Ocean represents a part of the global Ocean that has been less studied by modern oceanography than the Atlantic and Pacific parts. This is remarkable, since the Indian Ocean was subject to much historic exploration through navigators from Asia, India, the Middle East and lastly from Europe. This unique, comprehensive reference set on the Indian Ocean, covers all oceanographical aspects with its physics, chemistry, biology and geology in 21 peer-reviewed expert-written chapters. Besides the well-ground basis on the Ocean’s characteristics and a wealth of data, some unique features presented are the monsoon - the biennial reversal of winds and the resultant surface circulation; the tropical and sub-tropical jet streams, namely the Somali current, the Agulhas current and the Leevwin current; the oxygen-poor intermediate waters in its northern part which significantly contribute several green house gases to the atmosphere, for example, carbon dioxide, nitrous oxide, methane and dimethyl sulphide; its exhaustive coral reefs and mangrove vegetation; and the polymetallic nodules at its depths and its other mineral resources. Moreover, an analysis is provided of the anthropogenic contributions and their impacts on the health of the Indian Ocean; and that of estuary environments of important rivers of the 15 littoral countries. Intended for research scientists, professionals and students working in physical, chemical and geological oceanography.
