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.

A true story of catastrophe and survival at sea, "Fatal Forecast" is a spellbinding moment-by-moment account of seventy-two hours in the lives of eightyoung fishermen, some of whom would never set foot on dry land again.

On the morning of November 21, 1980, two small Massachusetts lobster boats set out for Georges Bank, a bountiful but perilous fishing ground 130 miles off thecoast of Cape Cod. The National Weather Service had forecast typical fallweather, and the young, rugged crewmen aboard the "Sea Fever" and the "Fair Wind" had made dozens of similar trips that season. They had no reasonto expect that this trip would be any different.

But the only weather buoy on Georges Bank was malfunctioning, and the NationalWeather Service had failed to share this fact with the fishermen who dependedon its forecasts. As the two small boats headed out to sea, a colossal storm wasbrewing to the southeast, a furious maelstrom the National Weather Service didnot accurately locate until the boats were already caught in the storm's grip, trapped in the treacherous waters of Georges Bank.

Battered by sixty-foot waves and hurricane-force winds, the crews of the "FairWind" and the "Sea Fever" (captained by Peter Brown, whose father ownedthe "Andrea Gail" of "Perfect Storm" fame) struggled heroically to keep their vessels afloat. But the storm soon severely crippled one boat andoverturned the other, trapping its crew inside.

Meticulously researched and vividly told, "Fatal Forecast" is first andforemost a tale of miraculous survival. Most amazing is the story of Ernie Hazzard, who managed to crawl inside a tiny inflatable life raft and then spentmore than fifty terrifying hours adrift on the stormy open sea. By turns tragic, thrilling, and inspiring, Ernie's story deserves a place among the greatestsurvival tales ever told.

Equally riveting are the stories of the brave men and women from the Coast Guardand the crew of a nearby fishing boat who imperiled their own lives that day inorder to save the lives of others.

As gripping and harrowing as "The Perfect Storm" - but with a miracle ending - "Fatal Forecast" is an unforgettable true story about the collision of two spectacular forces: the brutality of nature and the human willto survive.

"Magnificent . . . A joyful, hopeful book. Safina gives us ample reasons to be enthralled by this astonishing ancient animal--and ample reasons to care.""--Los Angeles Times" As Carl Safina's compelling natural history adventure makes clear, the fate of the leatherback turtle is in our hands.

We accompany award-winning natural history expert Safina and his colleagues as they track leatherbacks across the world's oceans and onto remote beaches of every continent, including a thrilling journey from Monterey, California, to nesting grounds in Papua, New Guinea. Throughout, in his peerless prose, Safina captures the delicate interaction between these gentle giants and the humans who are playing a significant role in their survival.

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.

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.

Caustics are natural phenomena, forming light patterns in rainbows or through drinking glasses, and creating light networks at the bottom of swimming pools. Only in recent years have scientists started to artificially create simple caustics with laser light. However, these realizations have already contributed to progress in advanced imaging, lithography, and micro-manipulation. In this book, Alessandro Zannotti pioneers caustics in many ways, establishing the field of artificial caustic optics. He employs caustic design to customize high-intensity laser light. This is of great relevance for laser-based machining, sensing, microscopy, and secure communication. The author also solves a long standing problem concerning the origin of rogue waves which appear naturally in the sea and can have disastrous consequences. By means of a far-reaching optical analogy, he identifies scattering of caustics in random media as the origin of rogue waves, and shows how nonlinear light-matter interaction increases their probability.

This book explores computational fluid dynamics applied to ship hydrodynamics and provides guidelines for the future developments in the field based on the Tokyo 2015 Workshop. It presents ship hull test cases, experimental data and submitted computational methods, conditions, grids and results. Analysis is made of errors for global (resistance, sinkage, trim and self-propulsion) and local flow (wave elevations, mean velocities and turbulence) variables, including standard deviations for global variables. The effects of grid size and turbulence models are evaluated for both global and local flow variables. Detailed analysis is made of turbulence modeling capabilities for capturing local flow physics. Errors and standard deviations are also assessed for added resistance (captive test cases) and course keeping/speed loss (free running test cases) in head and oblique waves. All submissions are used to evaluate the error and uncertainty by means of a systematic verification and validation (V&V) study along with statistical investigations.
