This unrivalled reference book is the first in the new Springer-Praxis Earth System Science Series. Written by a team of global experts, this new book describes mankind s destruction of the Aral Sea. Dr Philip Micklin and team explain how spheres and events interact and reveal the social, psychological, political and economic consequences of the "Aral Sea Problem" together with some lessons of how to potentially rehabilitate portions of the sea.

International experts in the field have contributed to the work including Praxis author Dr. Zavialov, covering physical oceanography and also Dr. Vitaliy Bortnik, the leading expert on the hydrometeorology and hydrochemistry of the Aral at the end of the Soviet period. Other pioneering experts have contributed chapters covering climatology; archaeological and paleobotanical evidence for ascertaining the level variation history of the Aral Sea; landscape dynamics of the Amu Dar ya Delta owing to drying of the sea; use of radar altimetry to trace sea level changes and much more.

The book is structured into six core parts. The first part sets the scene and explains how the use of Aral basin water resources, primarily used for irrigation, have destroyed the Aral Sea. The team explains how spheres and events interact and the related problems. Part 2 examines the social consequences of the ecological catastrophe and the affect of the Aral Sea desiccation on cultural and economic conditions of near Aral region. Part 3 explores the scientific causes of the destruction using detailed analyses and data plus some of their own research spanning aquatic biology, terrestrial biology, hydrology, water management and biodiversity. They also share some of the latest archaeological discoveries and paleobotanical analysis to delineate past levels and characteristics of the Aral Sea. There is particular focus on modern remote sensing and GIS techniques and how they can monitor the Aral Sea and the environment. Part 4 discusses regional and international initiatives to mitigate human and ecological problems of the Aral Sea and the wider political and economic consequences. With thorough insight of the total environment cost, the final chapters of the book will provide lessons for the future. There are insightful case studies throughout.

Multidisciplinary by nature, all titles in our new reference book series will explore significant changes within the Earth s ecosystems and to some extent, will tackle ways to think about our changing environment. "

The book provides acoustic images about sedimentary systems of the shelf edge, slope and deep-sea-floor. The knowledge gained can be used by both academia and hydrocarbon industry in a better understanding of continental margins and the processes shaping them. It is also of interest to colleagues in earth sciences involved in margin surveys for environmental studies. The current global trend in marine resource development is to move into deeper water, and this book can provide examples relevant to other passive margins around the world.

The book describes different approaches to the analysis of heat and dynamic processes in the ocean-atmospheric interface with satellite passive radiometric observations at microwaves. It examines the feasibility of determining synoptic, seasonal and year-to-year variations of sensible, latent and momentum fluxes to a useful accuracy using the DMSP SSM/I and EOS Aqua AMSR-E data directly from the measured brightness temperatures. An important object in the studies is the North Atlantic with emphasize on the areas with high midlatitude cyclon activity: here the main results have been obtained by combining data from the vessel experiments NEWFOUEX-88, ATLANTEX-90 and the data of microwave radiometers from the DMSP and EOS Aqua satellites. The role of vertical turbulent and horizontal advective heat transfer in forming interrelations between the brightness temperature of the system ocean-atmosphere and surface heat fluxes in the range of synoptic time scales is analyzed. Special sections of the book describe some results of analysis of reaction of the system ocean-atmosphere on passing of the tropical cyclone Katrina (August 2005) in the Florida Strait as well as a behavior of the system in the period of a time preceding to origination the cyclone Humberto (September 2007) in the Mexico Gulf. The long-term goal of this research is the search for effects and regularities, which can explain the reasons for the tropical cyclones appearance. Some characteristics of the tropical cyclones (brightness temperature and heat contrasts, etc.) are compared with those for midlatitude cyclones. At the same time as covering a key topic area with implications for global warming research, this text is also usefull to students who want to gain insight into application of satellite microwave radiometric methods for studying the air-sea interaction. Key themes: microwave radiometry, air-sea interaction, midlatitude and tropical cyclones, atmosphere boundary layer, heat and momentum surface fluxes.

The systematic description of the knowledge accumulated on the physical oceanography, marine chemistry and pollution, and marine biology of the Caspian Sea forms the basis of this book. It presents the principal characteristic features of the environmental conditions of the sea and their changes in the second half of the 20th century. At present, the principal problems of the Caspian Sea are related to the interannual sea level changes and their forecast and to the estimation of the intensity of the chemical pollution of the sea and its impact upon the biota. Special attention is paid to socio-economic, legal, and political issues in the Caspian Sea region. This publication is based on numerous observational data collected by the authors of the chapters during sea expeditions, on the archive data of several Russian oceanographic institutions, as well as on the broad scientific literature mainly published in Russian editions. This book is addressed to the specialists concerned with research in various fields of physical oceanography, marine chemistry, pollution studies, and biology; solving a wide scope of problems from the regional climate to the mesoscale processes; and using a variety of methods from remote sensing of the seas to numerical and laboratory modeling.

Thisvolumecontainsacollectionofpapersbyinternationalexpertsingeoph- ical ?uid dynamics, based upon presentations at a colloquium held in memory of Pedro Ripa on the ?rst anniversary of his untimely death. They review or present recent developments in hydrodynamic stability theory, Hamiltonian ?uid mechanics,balanceddynamics, waves,vortices,generaloceanographyand the physical oceanography of the Gulf ofCalifornia; all of them subjects in which Professor Ripamadeimportant contributions. His work, but also his friendly spiritandkindnesswerehighly regardedandappreciatedby colleagues and students alike around the world. This book is a tribute to his scienti?c legacy and constitutes a valuable reference for researchers and graduate s- dents interested in geophysical and general ?uid mechanics. Earlyin his career asa physicaloceanographer,Pedro Ripa made two la- mark contributions to geophysical ?uid dynamics. In 1981, he showed that the conservation of the potential vorticity is related to the invariance of the eq- tions of motion under the symmetry transformationsof the labels that identify the ?uid particles. That is, potential vorticity conservation is a consequence, via Noether's theorem, of the particle re-labelling symmetry. Two years later he published a paper entitled "General stability conditions for zonal ?ows in a one-layer model on the beta-plane or the sphere", where he established nec- sary conditions for stability in the shallow water equations, nowadays known as "Ripa's Theorem. " This is one of the very few Arnol'd-like stability con- tions that goes beyond two-dimensional or quasi-geostrophic ?ow, and stands alongside other famous stability criteria in making the foundations of the ?eld.

Recent global events such as the devastating 1998 Papua New Guinea tsunami, the 2004 Sumatran tsunami and the 2006 SE Asia undersea network cable failure underscore the societal and economic effects of submarine mass movements. These events call upon the scientific community to understand submarine mass movement processes and consequences to assist in hazard assessment, mitigation and planning. Additionally, submarine mass movements are beginning to be recognized as prevalent in continental margin geologic sections. As such, they represent a significant if not dominant role in margin sedimentary processes. They also represent a potential hazard to hydrocarbon exploration and development, but also represent exploration indicators and targets. This volume consists of a collection of the latest scientific research by international experts in geological, geophysical, engineering and environment aspects of submarine mass failures, focussed on understanding the full spectrum of challenges presented by submarine mass movements and their consequences.

Our desire to understand the global carbon cycle and its link to the climate system represents a huge challenge. These overarching questions have driven a great deal of scientific endeavour in recent years: What are the basic oceanic mechanisms which control the oceanic carbon reservoirs and the partitioning of carbon between ocean and atmosphere? How do these mechanisms depend on the state of the climate system and how does the carbon cycle feed back on climate? What is the current rate at which fossil fuel carbon dioxide is absorbed by the oceans and how might this change in the future? To begin to answer these questions we must first understand the distribution of carbon in the ocean, its partitioning between different ocean reservoirs (the "solubility" and "biological" pumps of carbon), the mechanisms controlling these reservoirs, and the relationship of the significant physical and biological processes to the physical environment. The recent surveys from the JGOFS and WOCE (Joint Global Ocean Flux Study and World Ocean Circulation Ex periment) programs have given us a first truly global survey of the physical and biogeochemical properties of the ocean. These new, high quality data provide the opportunity to better quantify the present oceans reservoirs of carbon and the changes due to fossil fuel burning. In addition, diverse process studies and time-series observations have clearly revealed the complexity of interactions between nutrient cycles, ecosystems, the carbon-cycle and the physical envi ronment."

Cohesive sediment, or mud, is encountered in most water bodies throughout the world. Often mud is a valuable resource, synonymous with fertile land, enriching the natural environment and used as an important building material. Yet mud also hinders navigation and consequently, dredging operations have been carried out since ancient times to safeguard navigation. Unfortunately, many mud deposits are now contaminated, endangering the eco-system and increasing the costs of dredging operations. The transport and fate of mud in the environment are still poorly understood and the need for basic research remains. This text contains the proceedings of the INTERCOH-2000 conference on progress in cohesive sediment research. It was the sixth in a series of conferences initially started by Professor Ashish Mehta in 1984 as a "Workshop on Cohesive Sediment Dynamics with Special Reference to the Processes in Estuaries". During these conferences the character of the first workshop has always been maintained, that is, small scale and dedicated to the physical and engineering aspects of cohesive sediments, without parallel sessions, but with ample time for discussions during and after the presentations, and followed by a book of proceedings containing thoroughly reviewed papers. INTERCOH-2000 was integrated with the final workshop of the COSINUS project. This project was carried out as a part of the European MAST-3 programme, and almost all European cohesive sediment workers were involved. INTERCOH-2000 focused on the behaviour and modelling of concentrated benthic suspensions, i.e. high-concentrated near-bed suspensions of cohesive sediment. Special attention was paid to: sediment - turbulence interaction; flocculation and settling velocity; high-concentrated mud suspensions; processes in the bed - consolidation; processes on the bed - erosion; field observations on mud dynamics; instrumentation; and numerical modelling.

Submarine mass movements represent major offshore geohazards due to their destructive and tsunami-generation potential. This potential poses a threat to human life as well as to coastal, nearshore and offshore engineering structures. Recent examples of catastrophic submarine landslide events that affected human populations (including tsunamis) are numerous; e.g., Nice airport in 1979, Papua-New Guinea in 1998, Stromboli in 2002, Finneidfjord in 1996, and the 2006 and 2009 failures in the submarine cable network around Taiwan. The Great East Japan Earthquake in March 2011 also generated submarine landslides that may have amplified effects of the devastating tsunami. Given that 30% of the World 's population live within 60 km of the coast, the hazard posed by submarine landslides is expected to grow as global sea level rises. This elevated awareness of the need for better understanding of underwater landslides is coupled with great advances in underwater mapping, sampling and monitoring technologies, laboratory analogue and numerical modeling capabilities developed over the past two decades. Multibeam sonar, 3D seismic reflection, and remote and autonomous underwater vehicle technologies provide hitherto unparalleled imagery of the geology beneath the oceans, permitting investigation of submarine landslide deposits in great detail. Increased and new access to drilling, coring, in situ measurements and monitoring devices allows for ground-thruthing geophysical data, provides access to samples for geotechnical laboratory experiments and unprecedented in situ information on strength and effective stress conditions of underwater slopes susceptible to fail. Great advances in numerical simulation of submarine landslide kinematics and tsunami propagation, particularly since the 2004 Sumatra tsunami, have also lead to increased understanding and predictability of submarine landslide consequences.
This volume consists of the latest scientific research by international experts in geological, geophysical, engineering and environmental aspects of submarine mass failure, focused on understanding the full spectrum of challenges presented by submarine mass movements and their consequences.

This thorough and informative volume presents a set of detailed, globally applicable techniques for seagrass research.
The book provides methods for all aspects of seagrass science from basic plant collection to statistical approaches and investigations of plant-animal interaction. The emphasis is on methods that are applicable in both developing and developed countries.

The importance of seagrasses in coastal and near shore environments, and ultimately their contribution to the productivity of the world's oceans, has become increasingly recognised over the last 40 years.
Seagrasses provide food for sea turtles, nearly 100 fish species, waterfowl and for the marine mammals the manatee and dugong. Seagrasses also support complex food webs by virtue of their physical structure and primary production and are well known for their role as breeding grounds and nurseries for important crustacean, finfish and shell fish populations. Seagrasses are the basis of an important detrital food chain. The plants filter nutrients and contaminants from the water, stabilise sediments and act as dampeners to wave action. Seagrasses rank with coral reefs and mangroves as some of the world's most productive coastal habitat and strong linkages among these habitats make the loss of seagrasses a contributing factor in the degradation of the world's oceans.

Contributors from around the world provide up-to-date methods for comparable collection of ecological information from both temperate and tropical seagrass ecosystems.

From the author of the international Bestseller Breath Covering a diving championship in Greece on a hot and sticky assignment for Outside magazine, James Nestor discovered free diving. He had stumbled on one of the most extreme sports in existence: a quest to extend the frontiers of human experience, in which divers descend without breathing equipment, for hundreds of feet below the water, for minutes after they should have died from lack of oxygen. Sometimes they emerge unconscious, or bleeding from the nose and ears, and sometimes they don't come up at all. The free divers were Nestor's way into an exhilarating and dangerous world of deep-sea pioneers, underwater athletes, scientists, spear fishermen, billionaires and ordinary men and women who are poised on the brink of some amazing discoveries about the ocean. Soon he was visiting the scientists who live 60ft underwater (and are permanently high on nitrous dioxide), swimming with the notorious man-eating sharks of Reunion and descending thousands of feet in a homemade submarine. And on the way down, he learnt about the amazing amphibious reflexes activated in the human body under deep-water conditions, why dolphins were injected with LSD in an attempt to teach them to talk, and why sharks like AC/DC. The sea covers seventy per cent of Earth's surface, and still contains answers to questions about the world we are only beginning to ask: Deep blends science and adventure to uncover its amazing secrets.

The enclosed and marginal seas surrounding the European continent exhibit a wide spectrum of environmental traits, ranging from sub-polar to sub-tropical climates, from shallow continental shelves to deep oceanic basins, from pristine marine reserves to regions impacted by countless economic and recreational activities. Understanding the inner workings of these seas a" aiming to reconcile the conflicting needs of protecting their ecological balance and exploiting their natural resources a" requires adequate observation systems, integrating both in situ and remote sensing techniques. This volume reviews the current potential of Earth Observations, while devoting particular attention to applications dealing with the issues, peculiarities and special challenges posed by the European Seas. The assessment of surface parameters by means of passive techniques a" which measure reflected visible and near-infrared sunlight, or surface emissions in the thermal infrared or microwave spectral regions a" is addressed. Active techniques a" which use transmitted impulses of visible or microwave radiation, for a subsequent evaluation of the signal returned by the water surface a" are covered as well. An in-depth analysis of the specific merits and drawbacks of each spectral region, and of both passive and active techniques, provides clues to help compose the unique mosaic of dynamical and bio-geo-chemical features of the European Seas.

A coastal sea area usually indicates a sea area between a continental shelf break with a water depth of about 200 m and the land shore. About 70% of global fish resources spend part of their life cycle in the coastal seas, which accounts for 90% of marine biomass yield. Freshwater and nutrients from the land have a great influence on the coastal seas, especially since more than half the human population lives within 100 km of a coast. Chemical reactions occur there rapidly between substances from the land as they encounter substances from the ocean. In terms of physics, a coastal sea acts as a boundary layer and kinetic energy is actively exchanged there. But if coastal oceanography were to be summed up in a single sentence, it would be the study that quantitatively makes clear the material transport in the coastal sea area'. Because the physical, chemical and biological processes relate to the material transport in the sea, it can be said the coastal oceanography is a genuinely interdisciplinary study. This book clarifies the quantitative material transport processes in the coastal sea area, mainly from a physical viewpoint.

Does there exist, deep within the earth's crust, a second biosphere-- composed of very primitive, thermophilic (heat-loving) bacteria, and containing more living matter than the entire surface? This idea, first proposed by the author in the early 1980s, is now supported by a growing body of evidence. The implications are astonishing: is the deep biosphere where life originated? Can Mars and other seemingly dead planets contain deep biospheres? Is there yet another--deeper, hotter--biosphere within the earth, based on silicon instead of carbon? This is the first book to explore this very controversial, intriguing theory.

Stimulated by Noah's Flood Hypothesis proposed by W. Ryan and W. Pitman in which a catastrophic inundation of the Pontic basin was linked to the biblical story, leading experts in Black Sea research (including oceanography, marine geology, paleoclimate, paleoenvironment, archaeology, and linguistic spread) provide overviews of their data and interpretations obtained through empirical scientific approaches. Among the contributors are many East European scientists whose work has rarely been published outside of Cyrillic. Each of the 35 papers marshals its own evidence for or against the flood hypothesis. No summary or overall resolution to the flood question is presented, but instead access is provided to a broad range of interdisciplinary information that crosses previously impenetrable language barriers so that new work in the region can proceed with the benefit of a wider frame of reference.

The emphasis now placed on the concept of sediment cells as boundaries for coastal defence groups, and the development of SMPs, should help CPAs realise the importance of natural processes at the coast when designing defence and protection schemes. However, this will only be the case where defence groups exist, and where CPAs take up the challenge of developing SMPs. Coastal landscapes have been produced by the natural forces of wind, waves and tides, and many are nationally or internationally important for their habitats and natural features. Past practices at the coast, such as the construction of harbours, jetties and traditional defence systems may have contributed to the deterioration of the coast. English Nature (1992) have argued that if practices and methods of coastal defence are allowed to continue, then coastlines would be faced with worsening consequences, including: The loss of mudflats and the birds which live on them Damage to geological Sites of Special Scientific Interest (SSSIs) and scenic heritage by erosion, due to the stabilisation of the coast elsewhere Cutting of sediment supplies to beaches resulting in the loss of coastal wildlife Cessation through isolation from coastal processes, of the natural operation of spits, with serious deterioration of rare plants, animals and geomorphological and scenic qualities (English Nature, 1992) A number of designations, provided by national and international legislation do exist to aid conservation.

The book addresses a weakness of current methodologies used in extreme value assessment, i.e. the assumption of stationarity, which is not given in reality. With respect to this issue a lot of new developed technologies are presented, i.e. influence of trends vs. internal correlations, quantitative uncertainty assessments, etc. The book not only focuses on artificial time series data, but has a close link to empirical measurements, in order to make the suggested methodologies applicable for practitioners in water management and meteorology.

Oceans play a pivotal role in our weather and climate. Ocean-borne commerce is vital to our increasingly close-knit global community. Yet we do not fully understand the intricate details of how they function, how they interact with the atmosphere, and what the limits are to their biological productivity and their tolerance to wastes. While satellites are helping us to fill in the gaps, numerical ocean models are playing an important role in increasing our ability to comprehend oceanic processes, monitor the current state of the oceans, and to a limited extent, even predict their future state.
Numerical Models of Oceans and Oceanic Processes is a survey of the current state of knowledge in this field. It brings together a discussion of salient oceanic dynamics and processes, numerical solution methods, and ocean models to provide a comprehensive treatment of the topic. Starting with elementary concepts in ocean dynamics, it deals with equatorial, mid-latitude, high latitude, and coastal dynamics from the perspective of a modeler. A comprehensive and up-to-date chapter on tides is also included. This is followed by a discussion of different kinds of numerical ocean models and the pre- and post-processing requirements and techniques. Air-sea and ice-ocean coupled models are described, as well as data assimilation and nowcast/forecasts. Comprehensive appendices on wavelet transforms and empirical orthogonal functions are also included.
This comprehensive and up-to-date survey of the field should be of interest to oceanographers, atmospheric scientists, and climatologists. While some prior knowledge of oceans and numerical modeling is helpful, the book includes an overview of enough elementary material so that along with its companion volume, Small Scale Processes in Geophysical Flows, it should be useful to both students new to the field and practicing professionals.
* Comprehensive and up-to-date review
* Useful for a two-semester (or one-semester on selected topics) graduate level course
* Valuable reference on the topic
* Essential for a better understanding of weather and climate

This volume is one outcome of the 6th International Conference on Paleoceano graphy (ICP VI). The conference was held August 23-28, 1998 in Lisbon, Portugal. The meeting followed the traditional format of a small number of invited oral presentations complemented by a large number ofcontributed posters. Over 550 participants attended, representing thirty countries and nearly 450 posters were presented. The invited speakers addressed the main themes of the 5oral sessions. The session topics were: Polar-Tropical and Interhemisphere Linkages; Does the Ocean Cause, or Respond to, Abrupt Climatic Changes?; Biotic Responses to Major Paleoceanographic Changes; Past Warm Climates; and Innovations In Monitoring Ocean History. This is the first time in ICP history that the Conference Proceedings are published. The aim of the organisers with the publication of this book is two-fold: to provide a useful review of the field and to document the ideas/controversies raised during the con ference that may stimulate future work. The book reflects the initial intentions of the conference, but it is not a conven tional conference proceedings, given that the papers have been reviewed by formal exter nal referees. Each of the conference topics is introduced by a review article designed to summarize the state of the art in each theme followed by articles prepared by the invited speakers. As with most conference proceedings, each theme is covered heterogenously. Some topics have all the expected contributions, others are less well covered."
