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 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.

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 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.

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 book presents current research into the effect that environmental conditions have on volcanic eruptions and the subsequent emplacement of volcanic products. This is accomplished through a series of chapters that investigate specific environments - both terrestrial and extraterrestrial - and the expression of volcanic materials found within those settings. Current state-of-the-art numerical, analytical and computer models are used in most chapters to provide robust, quantitative insights into how volcanoes behave in different environmental settings. Readership: Upper level undergraduates and new graduates. The book is primarily a presentation of research results rather than a tutorial for the general public. Textbook or supplementary reading for courses in volcanology or comparative planetology at college/university level.

Easter Island, a World Heritage Site is still, after over 50 years since Thor Heyerdahl's work on the island, a fascinating area to explore and learn about a culture that has only remnants remaining, while documenting a marine ecology still mostly unknown. Easter Island: Scientific Exploration into the World's Environmental Problems in Microcosm presents the research results from three years of interdisciplinary expeditions to Easter Island. The primary objectives were to investigate the effects of human population growth on the ecology of the island and to discover whether any dramatic climatic changes such as a prolonged El Nino could have disrupted the island's fragile ecosystem. The interdisciplinary scientific team were mainly researching the paleontology, archaeology, climatology, and geophysics of the island. This book now brings together the results of the three expeditions, identifies new areas of research, and hopefully will continue to inspire aspiring scientists to revisit this amazing island to explore and demystify this timeless enigma of human history.

The continental shelf seas have an importance which is out of proportion to the rela tively small fraction of the area of the global ocean which they occupy. These shallow seas play an important role as the high energy boundary zones of the deep ocean where much of the ocean's tidal and wave energies are dissipated. They are highly productive biologically and are responsible for most of the world's fishery production. In many cases, they are also sources of economically important resources, notably hydrocarbons and they are frequently important as thorough fares for merchant shipping. Because they are the regions of the ocean closest to our centres of population and industrial activity, they have been the first to feel the impact of the increasing pressures imposed by large scale waste disposal into the ocean. The North Sea is an archetypal representative of such seas: we need to be able to understand its processes and predict them if we are to achieve a degree of rational management in the future, as the environmental threats increase. The understanding required extends through a wide range of processes that operate in the shelf seas from the fundamental physics to the chemistry and biology of the water column and the seabed sediments. These processes, and the interactions between them, cut across the traditional discipline boundaries within marine science and require a substantial inter disciplinary effort for their effective study.

This book is devoted to the quantitative physical modeling of subduction and subduction-related processes. It presents a coherent description of the modeling method (including similarity criteria, and a novel applied experimental technique), results from model experiments, theoretical analysis of results on the basis of continuum mechanics, and their geodynamic interpretation. Subduction is modeled in general as well as applied to particular regions using both 2-D and 3-D approaches, with both slab-push and slab-pull driving forces. The modeling covers all stages from subduction initiation to death', different regimes of subduction producing back arc extension and compression, blocking of subduction and jumps of subduction zone, arc-continent collision and continental subduction. This work is for geologists and geophysicists interested in geodynamics of the convergent plate boundaries and in mechanics of the lithosphere.

Marine protected areas (MPAs) have an important role in marine conserva tion programmes around the world. Although most have been established relatively recently when compared with protected areas on land, there is considerable expertise on their identification, setting up and management. Some techniques have been adapted from those used on land. Others are novel, and unique to marine conservation. The chapters in this book give an insight into this fast developing field where experiment and innovation work alongside techniques which have been tried and tested. The guiding princi ples behind key stages in the setting up and management of MP As are described, and case studies illustrate how they have worked. While it is most encouraging to read about the successes, the case studies also point to difficulties which have been encountered. Not all of the examples are new or recent but, together, they illustrate what is happening in this field.

The results of an interdisciplinary research project on stability mechanisms and processes in the Wadden Sea ecosystem. The book describes distribution patterns of abiotic and biotic components over space and time and their regeneration following experimentally induced and natural disturbances -- analysed with multivariate statistics and ecological models. Recommendations for future research and consideration of stability mechanisms for the management of a dynamic system are also given.

Preface This book is the culmination of a workshop jointly organized by NATO and CEC on Climate-Ocean Interaction which was held at Lady Margaret Hall, Oxford University during 26-30 September 1988. The objective of the ARW was to assess the current status of research on climate-ocean interaction, with a major focus on the development of coupled atmosphere-ocean-ice models and their application in the study of past, present and possible future climates. This book contains 16 chapters divided into four parts: Introduction; Observations of the Climate of the Ocean; Modelling the Atmospheric, Oceanic and Sea Ice Components of the Climatic System; and Simulating the Variability of Climate on Short, Medium and Long Time Scales. A fifth part contains the reports of the five Working Groups on: Climate Observations, Modelling, ENSO Modelling and Prediction, Climate-Ocean Interaction on TIme Scales of Decades to Centuries, and Impact of Paleoclimatic Proxy Data on Climate Modelling. Preface ix Acknowledgements I thank Howard Cattle and Neil Wells for their guidance and assistance as members of the Workshop Organizing Committee. I particularly thank Michael Davey for all his efforts as Local Organizer to make the ARW a success. I also thank the staff of Lady Margaret Hall, Oxford University, for their help with the arrangements for the ARW.

The earth where we live is the only planet of our solar system that holds a mass of water we know as the ocean, covering 70.8% of the earth's surface with a mean depth of 3,800 m. When using the term ocean, we mean not only the water and what it contains, but also the bottom that supports the water mass above and the atmosphere on the sea surface. Modern oceanography thus deals with the water, the bottom of the ocean, and the air thereon. In addition, varied interactions take place between the ocean and the land so that such interface areas are also extended domains of oceanography. In ancient times our ancestors took an interest in nearshore seas, making them an object of constant study. Deep seas, on the other hand, largely remained an area beyond their reach. Modern academic research on deep seas is said to have been started by the first round-the-world voyage of Her Majesty's R/V Challenger I from 1872 to 1876. It has been only 120 years since the British ship leftPortsmouth on this voyage, so oceanography can thus be considered still a young science on its way to full maturity.

This monograph is an attempt to compile the present state of knowledge on ocean wave analysis and prediction. The emphasis of the monograph is on the development of ocean wave analysis and predic tion procedures and their utility for real-time operations and appli cations. Most of the material in the monograph is derived from journal articles, research reports and recent conference proceedings; some of the basic material is extracted from standard text books on physical oceanography and wind waves. Ocean wave analysis and prediction is becoming an important activity in the meteorological and oceanographic services of many countries. The present status of ocean wave prediction may be compar able to the status of numerical weather prediction of the mid-sixties and early seventies when a number of weather prediction models were developed for research purposes, many of which were later put into operational use by meteorological services of several countries. The increased emphasis on sea-state analysis and prediction has created a need for a ready reference material on various ocean wave analysis and modelling techniques and their utility. The present monograph is aimed at fulfilling this need. The monograph should prove useful to the ocean wave modelling community as well as to marine forecasters, coastal engineers and offshore technologists. The monograph could also be used for a senior undergraduate (or a first year graduate) level course in ocean wave modelling and marine meteorology.

Data assimilation is considered a key component of numerical ocean model development and new data acquisition strategies. The basic concept of data assimilation is to combine real observations via estimation theory with dynamic models. Related methodologies exist in meteorology, geophysics and engineering. Of growing importance in physical oceanography, data assimilation can also be exploited in biological and chemical oceanography. Such techniques are now recognized as essential to understand the role of the ocean in a global change perspective.
The book focuses on data processing algorithms for assimilation, current methods for the assimilation of biogeochemical data, strategy of model development, and the design of observational data for assimilation.

Senior level/graduate level text/reference presenting state-of-the- art numerical techniques to solve the wave equation in heterogeneous fluid-solid media. Numerical models have become standard research tools in acoustic laboratories, and thus computational acoustics is becoming an increasingly important branch of ocean acoustic science. The first edition of this successful book, written by the recognized leaders of the field, was the first to present a comprehensive and modern introduction to computational ocean acoustics accessible to students. This revision, with 100 additional pages, completely updates the material in the first edition and includes new models based on current research. It includes problems and solutions in every chapter, making the book more useful in teaching (the first edition had a separate solutions manual). The book is intended for graduate and advanced undergraduate students of acoustics, geology and geophysics, applied mathematics, ocean engineering or as a reference in computational methods courses, as well as professionals in these fields, particularly those working in government (especially Navy) and industry labs engaged in the development or use of propagating models.

Subtropical convergence regions in the southwestern Atlantic have a high biological productivity, and are important as nursery and feeding areas and as reproduction grounds for fishery stocks of subtropical and antarctic origin.
This book represents the first multidisciplinary treatise of this large and complex marine ecosystem. It analyses how subtropical convergence and land-sea interactions influence the coast, and sea and their biota. Synthesizing the rapidly expanding information, it provides a comprehensive appraisal of the biological resources, an assessment of their sustainable exploitation, and an evaluation of oceanographic processes. An inventory of all marine taxa in the southwestern Atlantic is included as an appendix.

Southern California is sandwiched between two tectonic plates with an ever-shifting boundary. Over the last several million years, movements of these plates have dramatically reshuffled the Earth's crust to create rugged landscapes and seascapes riven with active faults. Movement along these faults triggers earthquakes and tsunamis, pushes up mountains, and lifts sections of coastline. Over geologic time, beaches come and go, coastal bluffs retreat, and the sea rises and falls. Nothing about Southern California's coast is stable. Surf, Sand, and Stone tells the scientific story of the Southern California coast: its mountains, islands, beaches, bluffs, surfing waves, earthquakes, and related phenomena. It takes readers from San Diego to Santa Barbara, revealing the evidence for how the coast's features came to be and how they are continually changing. With a compelling narrative and clear illustrations, Surf, Sand, and Stone outlines how the coast will be altered in the future and how we can best prepare for it.

Increasing population, expanding industry and commerce, and tourism are placing added pressures on an already highly-utilized coastal zone. This book, through a series of case studies, illustrates the variety of changes already made along the coastlines of the world. The examples used are mainly from China, Japan, The Netherlands, and the United States, all countries with extensively engineered shorelines. Modifications emphasized include those associated with protection against coastal erosion, building of artificial beaches and islands, reclamation for aquaculture and agriculture, and the construction of harbors. The information in this book should be useful for all planners and engineers involved in the construction of coastal engineering works and for students interested in coastal modification.
