Beach Processes And Nearshore Hydrodynamics Of Dhanushkodi Rameswaram India

This book focuses on understanding the shoreline dynamics, nearshore processes and sediment transport around Rameswaram Island and the cities of Dhanushkodi and Arichamunai. Rameswaram Island is located between the Gulf of Mannar on the south and Palk Bay on the north, between the southern tip of India and Sri Lanka, and is unique in terms of physical, chemical and biological processes. The Gulf of Mannar is established as a marine biodiversity conservation area by its richness of variety and variability of marine species such as corals, finfish, shellfish and other fishes. The island is predominantly influenced by four seasons: northeast monsoon, post-monsoon, summer and southwest monsoon; and the sedimentological and hydrodynamic conditions significantly change seasonally, resulting in the island’s responding in a different manner with each season. It also explains the physical forces and their impacts around these areas. Rameswaram Island has existed naturally for a long period of time even under the influence of different water masses of the Gulf of Mannar and Palk Bay. Understanding the regional natural phenomena is the only solution to carry out the best management practices to develop coastal constructions and modifications.

Adam’s Bridge offers the first comprehensive transdisciplinary study of the famous eponymous tombolo (also known as Ram Setu) combining its sacral, historical, geological, political, performative, and heritage aspects into one framework, viewed under the critical lenses of island studies and cultural theory. The book elucidates the entanglement of Adam’s Bridge’s discursive history with India’s colonial history, contemporary geology, domestic politics, and the nation’s emerging position in a complex geopolitical order in and around the Indian Ocean region, vis-à-vis increasing Sino-American involvement in Indo-Sri Lankan relations. Without foregrounding any absolute scientific claims on the location of the sandbars that inspired sage Valmiki’s Ram Setu and the Ramayan legacy or hindering narratives of religious faiths and folklore revolving around the structure, this intellectual historiography traces the parallel evolution of traditions of compassionate questioning and devotion for Indic sacred beliefs among commentators across the millennia from both Indian and non-Indian spectra, seen in juxtaposition with the biotic and abiotic diversity of the Gulf of Mannar and Palk Bay. Looking beyond secular-versus-religious debates, this book will be of interest to scholars of ocean and island studies, coastal economies, archipelagic geographies, environmental history, heritage studies, colonial studies, and cultural theory. Adam’s Bridge unifies a consortium of themes, ranging across ecological and livelihood sustainability, environmentalism, soteriology, economic and geostrategic history, and the United Nations Convention on the Law of the Sea, in conceptualizing a compellingly nuanced chronicle for India’s enchanted ‘bridge.’

This book provides information on the causes, consequences, and possible solutions to modern environmental problems associated with ocean pollution with a particular focus on the Back Sea. The oceans are a vast but fragile complex. In recent decades, it has become especially manifest when ocean pollution has reached an unparalleled situation. Meanwhile, not only the well-being of ecosystems depends on the state of ocean waters, but human civilization largely depends on the oceans as a consequence of environmental dependence. This book examines the consequences of pollutants such as oil and hydrocarbon products (including plastics and microplastics), water acidification, sewage, wastewaters discharge into the ocean, thermal pollution, nuclear pollution, and biological pollution. Beyond the types of pollutants and their consequences, this book outlines the state of the art of the legal situation internationally regarding ocean pollution. The authors also show the current pollution of the inland seas, taking as an example of the Black Sea (anthropogenic and natural sources of pollution, its shelf, and shallow waters as well as international legislation). A part of the book analyzes the main types of environmental monitoring of the oceans and their role in solving ocean pollution problems with a particular interest in the Black Sea. The book is of interest to specialists in ocean pollution, ecologists, oceanologists, students, and graduate students studying oceanography, marine ecology, current methods of environmental monitoring, and legal problems related to the oceans and seas pollution, as well as to anyone interested in modern problems of the oceans.

This book provides a comprehensive overview of recent research on estuaries of the east coast of India, and how changing biogeochemical dynamics as a result of climate change and human activity have impacted estuaries and other open water ecosystems. Though estuaries only cover a very small portion of the earth’s hydrosphere, they are some of the most biogeochemically active regions among the global water bodies. As such, this book focuses on estuaries of the east coast of India going all the way to the Bay of Bengal, which is the world's largest freshwater input from perennial rivers and rain-fed estuaries, and is therefore a unique area of study. Through its unique coverage of the Bay of Bengal in particular, the book presents a new perspective not present in the literature on estuary biogeochemistry and ecosystem dynamics. Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life below Water), with a focus on ecosystem services of the natural aquatic system.The book will be useful to researchers, policy makers, coastal managers and marine sustainability scientists and organizations.

This book considers the formation of the signal reflected from the sea surface when sensing in the radio and optical range. Currently, remote sensing from space is the main source of information about the processes taking place in the atmosphere and ocean. The correct interpretation of remote sensing data requires detailed information about the rough surface that forms the reflected signal. The first three chapters describe the statistical and spatial-temporal characteristics of the sea surface, focusing on the effects associated with the nonlinearity of sea surface waves. The analysis makes extensive use of data obtained by the authors on a stationary oceanographic platform located on the Black sea. In the next seven chapters, the authors analyze how the nonlinearity of waves affects the formation of a signal reflected from the sea surface.This book is geared for advanced level research in the general subject area of remote sensing and modeling as they apply to the coastal marine environment. It is of value to scientists and engineers involved in the development of methods and instruments of remote sensing, analysis and interpretation of data. It is useful for students who have decided to devote themselves to the study of the oceans.

The book is dedicated to the study and mathematical definition of the biogeochemical patterns of organic and inorganic matter interaction with the marine environment's radioactive and chemical components. This book describes the radioisotope and mineral exchange theory between organic and inorganic matters in the marine environment on a time scale of metabolic processes and trophic interactions. The approach is parametrically compatible with modern techniques describing the matter and energy balance in aquatic ecosystems. The criteria for assessing the ecological capacity, biogeocenoses assimilation capacity, and water masses radio capacity, which form the basis of the theory of radioisotope and mineral homeostasis of marine ecosystems, are substantiated. This book presents methods to implement sustainable development of the Black Sea's critical and recreational zones according to the marine pollution factors. This book does that by regulating the balance between the consumption of water quality resources and their reproduction as a result of natural biogeochemical processes are proposed. The book is of interest to scientists working in marine geology, marine ecology, biogeophysics, and biogeochemistry. This book is also necessary for professionals working in institutions and administrations coordinating maritime activities, environmental projects, and developing aquaculture technologies.
