Book Description
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.

Book Description
This book “Facets of Contemporary History”is a selection of research papers, presented in the International Conference on Contemporary History which was held on 30th and 31st January 2015. This conference was organized by the Department of History, Tourism and Travel Management, Ethiraj College for Women, Chennai. It gives us great pleasure to put together a selection of the papers for the public in the form of a book in the interest of research. Contemporary History refers to the history of the immediate past or that which can be expected to remain in living memory. While there are areas of history which have branched off from contemporary history such as social history and economic history this conference took a very broad look at contemporary events from not just a historical but also a social science perspective. This Book contains 6 Sections namely Political History, Socio-Cultural History, Gender, Economic History, Environment and Tourism. We would like to place on record the Management of the college for the moral and financial support extended in the conduct of the Conference and in the production of the book. Thanks are due to our respected Chairman of the Trust Board, Mr. V.M.Muralidharan for all his support and encouragement. Heartfelt thanks are due to Prof.Dr.Karu. Nagarajan Member Secretary, TAMIL NADU STATE COUNCIL FOR HIGHER EDUCATION for their generous financial Assistance towards the conduct of the Conference. We would be failing in our duty if we do not thank the faculty of the Department of History, Tourism and Travel Management for their support and encouragement in the conduct of the Conference.

Book Description
Estuaries are among the most complex and complicated ecosystems in the biosphere because they are at the interface of terrestrial, freshwater, and marine systems. Estuaries and the lands surrounding them are places of transition from land to sea and from fresh to salt water. Although influenced by the tides, estuaries are protected from the full force of ocean waves, winds, and storms by the reefs, barrier island or fingers of land, mud or sand that define an estuary's seaward boundary. In India, estuaries have been a focal point of activities for human settlement, for development of port and harbors. The health status and the biological diversity of the Indian estuarine ecosystem are deteriorating day-by-day through man-made activities and dumping of enormous quantities of sewage and industrial effluent. Estuaries are ecologically very important because it provides vital habitats for thousands of marine species. They are "nurseries of the sea", as it is an ideal location for fish, shellfish, and other marine animals to reproduce in protected environment and availability of abundant food. Besides, estuaries are important for the health of the oceans as it can filter sediment and pollutants from the water before it flows into the oceans. Estuaries are vulnerable to excessive loading of nutrients by runoff containing fertilizer and other pollutants. In recent decades, population growth and related activities (agricultural practices, wastewater treatment plants, urban run-off, and the burning of fossil fuels) have increased nutrient inputs by many folds than the levels that occur naturally. The present book Eutrophic Status of Narmada and Tapi Tropical Estuaries of Gujarat, India point-out an intensive study at two major estuaries (Narmada, Tapi) of Gujarat, India. The authors have investigated hydrochemistry, geochemistry, phytoplankton, zooplankton, and benthic community, along with site-specific problems and their suggestions in both the estuarine environs. This book will certainly be a ready reference guide to the students, researchers, academicians, scientists, and riverine and marine authorities of Gujarat and India, to enrich their knowledge in cutting edge of research in the field of estuarine ecology, biodiversity, conservation, restoration, and management.

Book Description
This volume compiles recent research on phytoplankton primary productivity (PP) in the Indian Ocean to provide an understanding and consolidation of the driving mechanisms of PP variability in diverse oceanic ecosystems globally. The book aims to facilitate a holistic overview of the research carried out in this field in various oceanic realms such as Indian coastal and oceanic waters (estuaries, coastal waters, Bay of Bengal, Arabian Sea, Indian Ocean). The contents of this book also address the United Nations sustainable development goals i.e., SDG 13 (Climate Action) and SDG 14 (Life below Water), with a focus on the impacts of climate change oceanic ecosystems. The book can serve as a comprehensive baseline of information for researchers studying planktonic primary productivity and biogeochemistry-related research in the above-mentioned marine ecosystems and other global oceans. It is intended to attract the attention of researchers, professionals, undergraduate and graduate oceanography students, and policy makers in the field of marine sciences.

Book Description
Coral reefs are among Earth's most diverse, productive, and beautiful ecosystems, but until recently, their ecology and the means to manage them have been poorly understood and documented. In response to the inadequate information base for coral reefs, this book reviews the ecological and conservation status of coral reefs of the Western Indian Ocean, bringing together presentations of the region's leading scientists and managers working on coral reefs.Coral Reefs of the Indian Ocean: Their Ecology and Conservation starts with a general overview of the biogeography of the region and a historical account of attempts to conserve this ecosystem. It goes on to describe the state of the reefs in each of the countries with coral reefs, and it concludes with a series of management case studies.The book also summarizes most of the existing ecological information on reefs in this region and efforts at management, making it useful for students, teachers, and investigators interested in tropical or marine ecology, conservation biology and management, and environmental sciences.

Book Description
The main objective of bringing out a book of this sort is to popularize the story of transcontinental migrant shorebirds visiting the West Coast region of India. The book focuses mainly on two major issues (on the basis of thorough scientific study): 1. The shorebirds are ecological indicators of wetland health on a global scale. It is a matter of serious international conservation concern that shorebird populations are declining all over the world, with many species and populations facing imminent threats of endangerment or extinction. The population of migrant shorebirds coming to our West Coast has been declining drastically. This finding is an outcome of dedicated and systematic scientific investigation (as a part of the doctoral work of Dr. Aarif) made in the West Coast, focusing on Kadalundi-Vallikkunnu Community reserve (KVCR). KVCR, one of the four community reserves in India, supports transcontinental migratory shorebirds in Central Asian Flyway (CAF). The CAF covers thirty countries, of which India is one of the dominant wintering grounds for shorebirds. 2. Shorebirds can be regarded as global sentinels of environmental changes due to their migratory ecology and habitat use patterns. For long-distant migrants, the ecological quality of wintering ground appears to be of key importance. The West Coast of India faces environmental threats due to anthropogenic activities. Habitat destruction, solid waste dumping, sand mining, and so on are subjected to scientific study in KVCR. The role of man-made infrastructures in/near the habitat like roads, bridges, mobile towers, etc., were also subjected to study. The consequences of these anthropogenic activities on the survival of macrobenthic invertebrates (major prey items of shorebirds) and their habitats have been studied following proven scientific methods. The dominance of humans and their population explosion are likely to competitively exclude many species of migrant shorebirds. Declining food resources and reduced suitability of stopover sites have far-reaching implications on the reproduction and survival of migrant shorebirds. Climate change due to anthropogenic activities may exacerbate the situation. The book focuses on the major environmental threats and suggests specific management plans for reducing the cumulative impacts on West Coast in General and Kadalundi-Vallikkunnu Community Reserve in particular. If the anthropogenic pressures on this ideal stopover site of transcontinental migrant shorebirds continue to escalate at the same pace, the winged visitors may find other suitable habitats for wintering and foraging. The music of the fluttering wings may be silenced if we do not wake up to this dire situation. The authors are apprehensive of this silence settling on the shores all over the world.
