This volume contains the proceedings of a Symposium held at the University of Kiel, Germany, from 31 March to 6 April, 1971. The Symposium was organized by the Scientific Committee on Oceanic Research (SCOR) and the Marine Productivity section of the International Biological Programme (IBPIPM) with the assistance of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Food and Agriculture Organization (FAO), and the International Association of Biological Oceanography (IABO). The aim of the Symposium was to summarize present knowledge of the biology of the Indian Ocean. Twenty-two presentations by invited speakers reviewed the research work carried out during the International Indian Ocean Expedition (lIOE) 1959 -1965, the first cooperative project coordinated by the Intergovernmental Oceanographic Commission (IOC). In addition, reports were presented of postexpedition examination of material and of more recent investigations relevant to the aims of the lIOE. In keeping with the aims of "Ecological Studies", the present volume contains much new information and some synthesis, all directed towards obtaining an understanding of the functioning and organization of the ecosystem of the Indian Ocean. The plan of the Symposium was to present the relevant meteorological, physical, chemical and geological background and to follow this with the various aspects of biological oceanography. Because of the uneven stage of development of the different disciplines, the papers included in this volume vary in their analytical level.

The Indian Ocean and its Role in the Global Climate System provides an overview of our contemporary understanding of the Indian Ocean (geology, atmosphere, ocean, hydrology, biogeochemistry) and its role in the climate system. It describes the monsoon systems, Indian Ocean circulation and connections with other ocean basins. Climatic phenomena in the Indian Ocean are detailed across a range of timescales (seasonal, interannual to multi-decadal). Biogeochemical and ecosystem variability is also described. The book will provide a summary of different tools (e.g., observations, modeling, paleoclimate records) that are used for understanding Indian Ocean variability and trends. Recent trends and future projections of the Indian Ocean, including warming, extreme events, ocean acidification and deoxygenation will be detailed. The Indian Ocean is unique and different from other tropical ocean basins due to its geography. It is traditionally under-observed and understudied, yet plays a fundamental role for regional and global climate. The vagaries of the Asian monsoon affect over a billion people and a third of the global population live in the vicinity of the Indian Ocean. It is also particularly vulnerable to climate change, with robust warming and trends in heat and freshwater observed in recent decades. Advances have recently been made in our understanding of the Indian Ocean's circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales. As such, this book is the perfect compendium to any researcher, student, teacher/lecturer in the fields of oceanography, atmospheric science, paleoclimate, environmental science, meteorology and geology, as well as policy managers and water resource managers. - Provides interdisciplinary content with a comprehensive overview for students and practitioners from a wide range of disciplines as well as for stakeholders - Presents a broad overview and background on the current state of knowledge of the variability, change, and regional impacts of the Indian Ocean - Includes links to animations, slideshows, and other educational resources

This open access book discusses the impact of human-induced global climate change on the regional climate and monsoons of the Indian subcontinent, adjoining Indian Ocean and the Himalayas. It documents the regional climate change projections based on the climate models used in the IPCC Fifth Assessment Report (AR5) and climate change modeling studies using the IITM Earth System Model (ESM) and CORDEX South Asia datasets. The IPCC assessment reports, published every 6–7 years, constitute important reference materials for major policy decisions on climate change, adaptation, and mitigation. While the IPCC assessment reports largely provide a global perspective on climate change, the focus on regional climate change aspects is considerably limited. The effects of climate change over the Indian subcontinent involve complex physical processes on different space and time scales, especially given that the mean climate of this region is generally shaped by the Indian monsoon and the unique high-elevation geographical features such as the Himalayas, the Western Ghats, the Tibetan Plateau and the adjoining Indian Ocean, Arabian Sea, and Bay of Bengal. This book also presents policy relevant information based on robust scientific analysis and assessments of the observed and projected future climate change over the Indian region.

Over the past ten years, a number of new large-scale oceanographic programs have been initiated. These include the Climate Variability Program (CLIVAR) and the recent initiation of the Geochemical Trace Metal Program (GEOTRACES). These studies and future projects will produce a wealth of information on the biogeochemistry of the world's oceans. Aut

The Lakshadweep islands are a group of 36 coral islands in the Indian Ocean. These small islands are unique for their aquatic bio-diversity and vast blue lagoons. This book presents the results of studies done by the authors during the period 1990 to 2009 that address the beach morphology, hydrodynamics, energy resources and management options with special reference to the issue of both natural and anthropogenic coastal erosion. The relatively low island elevation makes the islands more susceptible to high-wave attack and coastal flooding during adverse weather conditions. The islands are also prone to risks from episodic events like cyclones and deep depressions. This highlights the need for a comprehensive study of the wave, climate and coastal processes at work during different seasons to delineate the factors responsible for shoreline changes and also to identify the locations that need protection and the management options. This book will serve as a guide to researchers, scholars and students who are interested in the coastal processes of coral islands.

Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features may have the same origin. This book follows a logical progression from geological and physical processes, ecology, biology and biogeography, to exploitation, management and conservation concerns. In 21 Chapters written by 57 of the world’s leading seamount experts, the book reviews all aspects of their geology, ecology, biology, exploitation, conservation and management. In Section I of this book, several detection and estimation techniques for tallying seamounts are reviewed, along with a history of seamount research. This book represents a unique and fresh synthesis of knowledge of seamounts and their biota and is an essential reference work on the topic. It is an essential purchase for all fisheries scientists and managers, fish biologists, marine biologists and ecologists, environmental scientists, conservation biologists and oceanographers. It will also be of interest to members of fish and wildlife agencies and government departments covering conservation and management. Supplementary material is available at: www.seamountsbook.info

The Indian Ocean: Basics of Marine Geology, Physics and Chemistry begins with a short introduction to the and origin of water and formation of oceans on Earth. This is followed by the history of Oceanography / Marine Sciences, including international and Indian scenarios. In subsequent chapters marine instruments, sampling equipment, coastal features, offshore and deep-sea feature, and structures are discussed. Oceanic volcanism, formation of different rocks and geotectonics (continental drift, plate tectonics, seafloor spreading) are detailed, as these play important roles in the evolution of Earth. Sediments of the coasts and deep sea are presented in terms of their classifications, granulometry, chemical compositions and other parameters. The properties of sea water, oceanic circulation and cycling of nutrients form the crux of physical oceanography. The Indian Ocean: Basics of Marine Geology, Physics and Chemistry includes a chapter on the biology of the oceans, and their importance to sediment formation and palaeoceanography form another chapter. A chapter on mineral wealth of the coasts (near- and off-shore) and deep sea is included and contains beach sands, placer deposits, polymetallic nodules, phosphorites, hydrothermal polymetallic sulphides. In addition, the economics of mining these deposits are covered. Information related to harnessing various energies from the sea such as from tides, waves, currents and winds are incorporated. The Indian Ocean also deals with the important aspects of territorial waters, exclusive economic zones and coastal regulation zones together with international maritime laws, rules and regulations. A chapter pertaining to blue economy and green technology of the oceans are also presented. The highlight of the book is the inclusion of details, examples and photographs from Indian coasts and neighboring seas (especially Arabian Sea and Bay of Bengal) and the Indian Ocean. Presents the Indian Ocean in the context of global ocean circulation and climate Includes a modern, comprehensive, coherent treatment of the Indian Ocean's physical, chemical and biological oceanography Provides examples and case studies related to India, that can also be applied elsewhere

This book explores the immense potential of the Indian Ocean region, and how best to maintain sustainable and responsible economic and strategic activities. The combination of science, innovation, and entrepreneurship will create the new blue economy business model, which has the potential to transform society.
