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.

Multi-scale systems, involving complex interacting processes that occur over a range of temporal and spatial scales, are present in a broad range of disciplines. Several methodologies exist to retrieve this multi-scale information from a given time series; however, each method has its own limitations. This book presents the mathematical theory behind the stochastic analysis of scaling time series, including a general historical introduction to the problem of intermittency in turbulence, as well as how to implement this analysis for a range of different applications. Covering a variety of statistical methods, such as Fourier analysis and wavelet transforms, it provides readers with a thorough understanding of the techniques and when to apply them. New techniques to analyse stochastic processes, including empirical mode decomposition, are also explored. Case studies, in turbulence and ocean sciences, are used to demonstrate how these statistical methods can be applied in practice, for students and researchers.

Deep-water coral reefs are found along large sections of the outer continental shelves and slopes of Europe, from North Cape to the Gulf of Cadiz, and because they also occur along the Atlantic seaboard of USA, the Gulf of Mexico, off Brazil, in the Mediterranean, and off New Zealand, they are currently being targeted by international groups of marine scientists. They have become popular and opportune deep-water research targets because they offer exciting frontier exploration, combined with a whole plethora of modern scientific methods, such as deep-sea drilling, sampling, remote control surveying and documentation. Furthermore they represent timely opportunities for further developments within the application of geochemistry, stable isotope research, bacterial sciences, including DNA-sequestering, and medical research (search for bioactive compounds). The Integrated Ocean Drilling Program (IODP) has arranged a deep-sea scientific drilling campaign on giant carbonate banks off Ireland. Because the reefs currently defy traditional marine-ecological theories, they represent future research opportunities and will enjoy scientific scrutiny for many years to come.

Arctic marine ecosystems are largely impacted by changes associated with global warming. The sea ice in Greenland Sea plays an important role in regional and global climate system. The book investigate the relationships between phytoplankton biomass, measured using remotely sensed chlorophyll-a (CHL), aerosol optical depth (AOD) and sea-ice cover (ICE) in the Greenland Sea (20 DegreesW-10 DegreesE, 65-85 DegreesN) over the period 2003-2012. First hand Satellite data was used to do correlation analysis. Enhanced statistics methods, such as lag regression method and cointegration analysis method are used for correlation and regression analysis between 2 variables (up to 3 variables). ARMA model was used to prediction time series in the future 3 years. The book not only gives outline of ecosystem in Greenland Sea, how the ice impact to the local ecosystems, but also provides valuable statistical methods on analysis correlations and predicting the future ecosystems.

This textbook offers a comprehensive and authoritative introduction to the latest analytical methods, tools and techniques used in the marine environment, bringing together the two fields of chemical oceanography and analytical chemistry. Divided into 11 chapters, the book starts with an overview of the main parameters of the marine carbon system, and it covers different sampling strategies used by the marine scientific community, and the different chemical analyses to measure trace metals, radionuclides and organic matter in the marine environment. Particular attention is given to the identification and quantification of marine persistent organic pollutants, emerging organic contaminants and microplastics. Readers will also find accessible explanations and real life examples of the application of remote sensing and in-situ sensing technologies to monitor the marine environment. The textbook finishes with a chapter on data treatment that outlines the relevant statistical approaches, uncertainty estimation and quality assurance of marine chemical measurements. This textbook provides both students and professionals alike with a transdisciplinary and comprehensive foundation for the chemical analysis of our oceans and seas.

Originally published in 1928 as part of the Cambridge Comparative Physiology Series, this book examines the effect of sea water on the growth of marine plants and animals as well as how the varying chemical makeup of seawater affects its circulation. Harvey covers topics such as temperature fluctuation, tidal streams, and the fertility of coastal areas, and supplies many charts and graphs in the text to illustrate key points. This book will be of value to anyone with an interest in the history of science and the study of the oceans.

Cotidal lines are lines on a map which connect points at which the same tidal level occurs simultaneously. Isaac Newton had explained the movement of the tides by the action of the moon and sun, and Daniel Bernoulli had used Newton's findings to create tide tables for specific locations, but William Whewell wanted to take research further by gathering and analysing information which would link cotidal points or lines across the world. Fellow and eventually Master of Trinity College, Cambridge, Whewell (1794 1866) published this work in 1833. In it he proposes various observations that would need to be undertaken to produce a cotidal map, with detailed descriptions of the factors to be taken into account in computing the results. In 1837, Whewell, several of whose other works are also reissued in this series, was awarded a royal prize medal by the Royal Society for his work on 'tidology'."

Beach renourishment is the restoration of beaches that have been depleted. The text deals with the sources of beach sediment as well as the causes and typical responses to beach erosion, before discussion of beach renourishment. Some of the first documented renourishment projects were undertaken in the early 1900's on the east coast of the United States. Several countries have since renourished beaches, particularly during the past few decades. Most projects have been in the United States, the United Kingdom, some European countries and Australia. These are reviewed and experience from various beach renourishment projects used for discussion of the following topics: 1. The need for preliminary investigations 2. Sources of sediment for beach renourishment 3. Methods of beach renourishment 4. Design considerations 5. Monitoring changes after beach renourishment 6. Assessment of performance 7. Modelling of beach renourishment 8. Beach renourishment for coast protection 9. Environmental impacts 10. Costs and benefits 11. Response of renourished beaches to a rising sea level

In later life the recipient of the Nobel Peace Prize for his humanitarian work, the explorer and scientist Fridtjof Nansen (1861 1930) encouraged and supported the 1901 voyage of his fellow Norwegian Roald Amundsen (1872 1928), publishing this account of its scientific findings in 1906. Amundsen had just purchased his famous boat, the Gjoa, and wanted to test her in Arctic waters. He planned to pay for the expedition by hunting seals, but wanted to carry out scientific work at the same time. On Nansen's advice, he decided to make oceanographic observations. After a six-month voyage, he returned with both observations and samples of water and plankton which considerably enlarged understanding of the bottom waters of the Norwegian Sea and the play of current in the area. Nansen's work supplies technical details, diagrams and maps from this remarkable scientific survey."

John Young Buchanan (1844-1925) was a Scottish chemist and oceanographer, he worked extensively on the chemistry of marine environments. Originally published in 1919, this book gathers together a selection of Buchanan's papers on a broad variety of topics, some of them non-scientific. Numerous illustrative figures are also included and the contents listing contains extensive notes on each of the papers. This book will be of value to anyone with an interest in the writings of Buchanan, chemistry, oceanography and the history of science.

Clay Sedimentology is a comprehensive textbook divided into six parts: - clay minerals and weathering - clay sedimentation on land - origin and behaviour of clay minerals and associated minerals in transitional environments (estuaries, deltas) and shallow-sea environments - diverse origins of clay in the marine environment - post-sedimentary processes intervening during early and late diagenesis - use of clay stratigraphic data for the reconstruction of past climate, marine circulation, tectonics, and other paleogeographical aspects. A basic idea on most topics dealing with sedimentary clays is presented and controversial data and uncertainties from the frontiers of knowledge are discussed.

The Arctic, the Antarctic, and the Hindu Kush-Himalayas form a trio of terrains sometimes called "the three poles". Mainly composed of rock, snow, and ice, these precious regions, which are home to many unique species such as the polar bear, the emperor penguin, and the snow leopard, contain the primary water resource of this planet and directly shape our climate. This book presents a first-ever global assessment and progressive review of the three poles and demonstrates the urgent need for their protection. Sins of the past have irrevocably harmed and threatened many of the unique qualities of these regions, and the future looks bleak with the global population forecast to reach 9 billion by 2060, and with climate change on the rise. Presented here is a wide-reaching and coherent overview of the three poles' biodiversity, habitats, and ongoing destruction. Failed protection and social targets set by the United Nations and other bodies are exposed while economic growth, unconstrained or inappropriate development, and urban sprawl are promoted unabated. Polar regions play a major role in the global agenda as they are rich in oil and other resources, marking them for contamination, overfishing, and further degradation. Tourism in the Antarctic has benefited from enlightened self-regulation, but there are signs that this is changing, too. The chapters of this book are written by experts in their fields, and their evidence leaves no doubt that we already live beyond our carrying capacity on a finite but decaying space. A global protection role model and several outlook scenarios are proposed to help set in motion polar protection priorities that are actually valid. Humanity has demonstrated through international treaties such as the Antarctic Treaty and the Madrid Protocol that we can put the interests of the planet as a whole first. This must become the norm, not the exception.

Barrier islands represent a complex coastal system that includes a number of different sedimentary depositional environments; nearshore zone, beach, dunes, washover fans, marshes, tidal flats, estuaries, lagoons, and tidal inlets. The morphodynamics of these fragile coastal systems provide a further complication to this coastal type. Although barrier islands comprise only 15% of the world's coastline, they have received a far greater proportion of attention from the scientific and engineering community, and more recently, from coastal managers and environmentalists. Modern barrier islands are arguably the most expensive and most vulnerable of all coastal environments. Pressure from developers for residential, industrial, and recreational development has caused most of our barriers to become significantly impacted by human activity, especially over the past few decades. These pres sures have led to extensive preservation of natural barriers through efforts from all levels of government and also by private organizations. Governments have also formed coastal management programs that help to control any future de velopment with the intent being to keep human activity compatible with barrier island morphodynamics. In order to devise appropriate coastal zone management programs, it is necessary to have a comprehensive understanding of the morpho dynamics of barrier island systems. This volume provides comprehensive details on barrier island morphology, sediment distribution, and the process-response mechanisms that cause changes to both. These are the important aspects of barrier systems that can provide important input into the development and implementation of coastal management programs."

Modern researchers in plate tectonics may be concerned with the analysis of distributed deformation across diffuse plate boundaries and triple junction zones. This book extends classic methods of kinematic analysis first developed in the 1960s to the more general scenarios of diffuse deformation zones between plates. The analytic methods presented specifically target the non-rigid deformation implied by unstable triple junction configurations. These methods are then applied to the tectonic evolution of western Caribbean region which provides new ways to test and challenge the established Pacific model of Caribbean tectonics. Possible advantages of the new Pirate model of Caribbean tectonics are discussed in terms of paleo-geography and paleo-ocean connections, as well as mineral and hydrocarbon potential and seismic risks across the region.

The book is an up-to-date basic reference for natural gas hydrate (NGH) in the Arctic Ocean. Geographical, geological, environmental, energy, new technology, and regulatory matters are discussed. The book should be of interest to general readers and scientists and students as well as industry and government agencies concerned with energy and ocean management. NGH is a solid crystalline material that compresses gas by about a factor of about 164 during crystallization from natural gas (mainly methane) - rich pore waters over time. NGH displaces water and may form large concentrations in sediment pore space. Its formation introduces changes in the geotechnical character of host sediment that allows it to be distinguished by seismic and electric exploration methods. The chemical reaction that forms NGH from gas and water molecules is highly reversible, which allows controlled conversion of the NGH to its constituent gas and water. This can be achieved rapidly by one of a number of processes including heating, depressurization, inhibitor injection, dissolution, and molecular replacement. The produced gas has the potential to make NGH a valuable unconventional natural gas resource, and perhaps the largest on earth. Estimates for NGH distribution, concentration, economic targets, and volumes in the Arctic Ocean have been carried out by restricting the economic target to deepwater turbidite sands, which are also sediment hosts for more deeply buried conventional hydrocarbon deposits. Resource base estimates are based on NGH petroleum system analysis approach using industry-standard parameters along with analogs from three relatively well known examples (Nankai-Japan, Gulf of Mexico-United States, and Arctic permafrost hydrate). Drilling data has substantiated new geotechnical-level seismic analysis techniques for estimating not just the presence of NGH but prospect volumes. In addition to a volumetric estimate for NGH having economic potential, a sedimentary depositional model is proposed to aid exploration in the five different regions around the deep central Arctic Ocean basin. Related topics are also discussed. Transport and logistics for NGH may also be applicable for stranded conventional gas and oil deposits. Arising from a discussion of new technology and methodologies that could be applied to developing NGH, suggestions are made for the lowering of exploration and capital expenses that could make NGH competitive on a produced cost basis. The basis for the extraordinarily low environmental risk for exploration and production of NGH is discussed, especially with respect to the environmentally fragile Arctic region. It is suggested that because of the low environmental risk, special regulations could be written that would provide a framework for very low cost and safe development.

The 2011 Tohoku earthquake generated a tsunami that caused severe damage including 20,000 casualties in Japan. The tsunami also affected other Pacific coasts, including the Kuril Islands, the USA, French Polynesia, the Galapagos Islands, Australia, and New Zealand. This volume contains an introduction and 21papers, mostly presented at the 25th International Tsunami Symposium held 1-4 July 2011, only four months after the tsunami. They report seismological aspects of the event related to the tsunami warning, the tsunami impacts and effects in Japan and around the Pacific, analyses of instrumental tsunami data and modelling.

Chapters are abundant with maps and illustrations.

This book provides an integrated view of Atlantic coastal Patagonian ecosystems, including the physical environment, biodiversity and the main ecological processes, together with their derived ecosystem services and anthropogenic impacts. It focuses on the key components of the aquatic ecosystem, covering the lower levels (plankton) to the top predators like large mammals and birds, before turning to human beings as consumers and shapers of coastal marine resources. The book then presents an overview of how organisms that constitute the aquatic food webs have changed through time and how they likely will soon change due to global change processes and anthropogenic pressures. In this regard it offers a wealth of information such as long-term patterns in physical / atmospheric processes, biodiversity and the distribution of marine organisms, as well as the results of experimental studies designed to understand their responses under future scenarios shaped by both climate change and anthropogenic pressures. The book also covers various aspects of the past, present and potential future relationship of human beings with Patagonian coastal environments, including the utilization of sea products, tourism, and growth of cities.

The primary goal here is to present a treatise on the significance and value of coarse clastic carbonate sediments (i.e. large coral boulders) on tropical coastlines for understanding both modern and pre-historical (Holocene) high-magnitude marine inundation events. There has been a rapid groundswell of interest in large carbonate blocks on tropical coasts over the last decade, yet it is not widely appreciated that such features were observed and recorded back in the early explorations of Matthew Flinders on the Great Barrier Reef in the 1800s. This book will illuminate how various characteristics of datable carbonate blocks torn up from coral reefs and deposited on reef platforms yield importance evidence about the storms and tsunamis that emplaced them over decadal and centennial timescales. No comprehensive review has so far been published. A need now exists for a 'definitive reference' on coral boulder research, which details the earliest observations, changing terminology, sedimentology, and relevance for coastal hazard research in the tropics. A wide range of examples will be incorporated from across Asia, Australia, the Pacific and the Americas, as well as a full up-to-date review of the existing literature.

Sea ice is a major component of polar environments, especially in the Arctic where it covers the entire Arctic Ocean throughout most of the year. However, in the context of climate change, the Arctic sea ice cover has been declining significantly over the last decades, either in terms of its concentration or thickness. The sea ice cover evolution and climate change are strongly coupled through the albedo positive feedback, thus possibly explaining the Arctic amplification of climate warming. In addition to thermodynamics, sea ice kinematics (drift, deformation) appears as an essential factor in the evolution of the ice cover through a reduction of the average ice age (and consequently of the cover's thickness), or ice export out of the Arctic. This is a first motivation for a better understanding of the kinematical and mechanical processes of sea ice. A more upstream, theoretical motivation is a better understanding of the brittle deformation of geophysical objects across a wide range of scales. Indeed, owing to its very strong kinematics, compared e.g. to the Earth s crust, an unrivaled kinematical data set is available for sea ice from in situ (e.g. drifting buoys) or satellite observations. Here, we review the recent advances in the understanding of sea ice drift, deformation and fracturing obtained from these data. We focus particularly on the scaling properties in time and scale that characterize these processes, and we emphasize the analogies that can be drawn from the deformation of the Earth s crust. These scaling properties, which are the signature of long-range elastic interactions within the cover, constrain future developments in the modeling of sea ice mechanics. We also show that kinematical and rheological variables such as average velocity, average strain-rate or strength have significantly changed over the last decades, accompanying and actually accelerating the Arctic sea ice decline.
