Deep Convection And Deep Water Formation In The Oceans

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book contains articles presenting current knowledge about the formation and renewal of deep waters in the ocean. These articles were presented at an international workshop at the Naval Postgraduate School in Monterey in March 1990. It is the first book entirely devoted to the topic of deep water formation in which articles have been both selected and reviewed, and it is also the first time authors have addressed both surface and deep mixed layers. Highlighted are: past and recent observations (description and analysis), concepts and models, and modern techniques for future research. Thanks to spectacular advances realised in computing sciences over the last twenty years this volume includes a number of sophisticated numerical models. Observational as well as theoretical studies are presented and a clear distinction is established between open-ocean deep convection and shelf processes, both leading to deep- and bottom-water formation. The main subject addressed is the physical mechanism by which the deep water in the ocean can be renewed. Ventilation occurs at the surface in areas called the gills, where water is mixed and oxygenated before sinking and spreading in the abyss of the deep ocean. This phenomenon is a very active area for both experimentalists and theoreticians because of its strong implications for the understanding of the world ocean circulation and Earth climate. This major theme sheds light on specific and complex processes happening in very restricted areas still controlling three quarters of the total volume of the ocean. All articles include illustrations and a bibliography. This book will be of particular interest to physical oceanographers, earth scientists, environmentalists and climatologists.

Interhemispheric Water Exchange In The Atlantic Ocean

218,63€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Recent results from modeling and observational studies demonstrate that the tropical Atlantic is a critical region for processes that maintain the meridional overturning circulation, such as cross-equatorial exchanges, and for sea surface temperature variability that impacts on climate variability of the coupled tropical ocean/atmosphere system. The theme of this book is the inter-hemispheric and inter-gyre exchanges of heat, salt and fresh water, while its goal is to improve the knowledge of the tropical Atlantic dynamics and how it affects the global ocean. A clear understanding of the dynamics of processes that affect the flow of mass and heat between the southern and the northern hemispheres in the upper few hundred meters in the tropical Atlantic and of those associated to the ocean circulation or to surface signals, from decadal, inter-annual to mesoscale periods, becomes necessary to better evaluate their contribution to the interhemispheric mass exchange. These processes are believed to be largely responsible in driving the sea surface temperature, which in turn, is a critical parameter to investigate ocean-atmospheric interactions. Output produced by regional models is also used to complement the observations and to provide additional information on their spatial and temporal variability. The subtropical cells, by bringing water masses subducted in the subtropics to the equator, and zonal currents investigated here contribute to the interhemispheric water exchange. Special attention is also given to the warm and salty anticyclonic rings shed by the North Brazil Current, which are now known to have a much broader impact, not only on interhemispheric water mass transfer, but also on the environment of remote regions. Observations from different sources are blended together, are used to validate model outputs and are also assimilated into models to obtain a more complete and accurate picture of the oceanic circulation and of its time evolution.

Applications In Coastal Modeling

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The importance of models to facilitate our understanding and management of the coastal system is evident from this book, which shows that the preference for using models to study the coastal system is shared not only by different research institutions (government, military, industry and academia), but also by researchers from diverse backgrounds. With contributions from several leading experts a variety of models - physical, analytical, numerical and computer simulation - are presented on various components of the coastal system.The book opens by examining the coast as a system, and provides an overview of models, systems concepts, and the systems approach. It next covers the simulation design process, stressing that modeling and simulation should form an interface between real-world processes, and the field of General Systems Theory. It is clearly shown that a system can be investigated with more than one type of model. For example, it is shown that waves can be studied with physical models, empirical and numerical models or with computer simulation models. Likewise, beaches can be investigated with physical, numerical or empirically-based models.The indispensability of models to enhance our understanding of coastal dynamics and associated component systems is emphasised. Mathematical modeling of rock coast development and the simulation of deltaic depositional systems are covered. A chapter on analytical modeling of predator-prey interactions highlights the fact that the coastal system also has biotic resources. Finally, problems which have to be overcome for the practical application of numerical and simulation models are discussed.The explanatory and detailed formulation of the various models, together with more than 100 figures, make this book worthwhile reading for senior undergraduates, graduate students, and all coastal researchers interested in the formulation and application of models of the coastal system.

Hydrodynamics Of Coastal Zones

de S.R. Massel

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book discusses selected theoretical topics of coastal hydrodynamics, including basic principles and applications in coastal oceanography and coastal engineering. It is not intended as a handbook; the emphasis is placed on presentation of a number of basic problems, rather than giving detailed instructions for their application. The bulk of the material deals with surface waves. In the author's opinion there is still a strong need for a book on wave phenomena in the coastal waters, as general textbooks on sea surface dynamics focus most of their attention on the deep ocean. This book intends to fill this need by concentrating on the phenomena typical of the coastal zone.Based on lectures given at the Institute of Hydroengineering, Polish Academy of Sciences in Gdansk, the approach throughout is a combination of the theoretical and observational. A basic knowledge of ordinary and partial differential equations, as well as the statistical and spectral analysis of time series, is assumed. The reader should also be familiar with fundamental hydrodynamic concepts.The book comprises nine chapters. Governing equations and conservation laws are treated in Chapter 1, using the variational principles. The theory of regular surface waves is covered in Chapters 2 to 4. The nonlinear effect of wave train modulation and their breaking of beaches is examined in Chapter 5. Chapters 6 and 7 focus on the statistical and spectral treatment of waves induced by wind. Current generation and circulation pattern are the subject of Chapter 8, while sea level variations are examined in Chapter 9. References for further reading are given at the end of each chapter.

de W.Y. Tan

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Within this monograph a comprehensive and systematic knowledge on shallow-water hydrodynamics is presented. A two-dimensional system of shallow-water equations is analyzed, including the mathematical and mechanical backgrounds, the properties of the system and its solution. Also featured is a new mathematical simulation of shallow-water flows by compressible plane flows of a special virtual perfect gas, as well as practical algorithms such as FDM, FEM, and FVM. Some of these algorithms have been utilized in solving the system, while others have been utilized in various applied fields. An emphasis has been placed on several classes of high-performance difference schemes and boundary procedures which have found wide uses recently for solving the Euler equations of gas dynamics in aeronautical and aerospatial engineering. This book is constructed so that it may serve as a handbook for practicians. It will be of interest to scientists, designers, teachers, postgraduates and professionals in hydraulic, marine, and environmental engineering; especially those involved in the mathematical modelling of shallow-water bodies.

Marine Physics

de J. Dera

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 In trying to discover as much as possible about the marine environment, oceanography has split into many subdisciplines, each represented by innumerable publications. To date however, there has been no concise synthesis introducing readers to the whole array of physical processes in the sea, and showing how these processes are related to one another and to other natural phenomena. The author of Marine Physics aims to fill this gap.The volume presents energy and mass transfer processes in the marine environment together with an explanation of their effects on other processes. Starting with a general introduction to the thermodynamics of ocean waters, there follow chapters on radiation transfer processes; the molecular exchange of mass, heat and momentum; the turbulent exchange of mass, heat and momentum; small-scale air-sea interactions; modelling the surface boundary layer; and the propagation of acoustic waves in the sea. The discussions begin with physical principles and culminate in a presentation of current research problems. The volume is completed with the presentation of basic quantities, equations, formulas and diagrams, as well as indexes and 576 literature references. This volume should be an invaluable resource to post-graduates and scientists in the fields of engineering and oceanography, and for those interested in the protection or exploitation of the marine environment.

Marine Mineral Exploration

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The past 20 years have seen extensive marine exploration work by the major industrialized countries. Studies have, in part, been concentrated on Pacific manganese nodule occurrences and on massive sulfides on mid-oceanic ridges. An international jurisdictional framework of the sea-bed mineral resources was negotiated by the United Nations Conference on the Law of the Sea (UNCLOS III). A most important outcome of this conference was the establishment of an Exclusive Economic Zone (EEZ) of at least 200 nautical miles for all coastal states and the recognition of a deep-sea regime.Mineral deposits in EEZ areas are fairly unknown; many areas need detailed mapping and mineral exploration, and the majority of coastal or island states with large EEZ areas have little experience in exploration for marine hard minerals. This book describes the systematic steps in marine mineral exploration. Such exploration requires knowledge of mineral deposits and models of their formation, of geophysical and geochemical exploration methods, and of data evaluation and interpretation methods. These topics are described in detail by an international group of authors. A short description is also given of marine research vessels, evaluation of marine exploration examples; and an overview is provided of the jurisdictional situation after UNCLOS III.

Global Ecological Consequences Of The 1982-83 El Nino-Southern Oscillation

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 El Nino is a meteorologic/oceanographic phenomenon that occurs sporadically (every few years) at low latitudes. It is felt particularly strongly in the eastern Pacific region, notably from the equator southwards along the coasts of Ecuador and Peru. The El Nino is a component of the ENSO (El Nino Southern Oscillation) which accentuates the intimate and causal connection between atmospheric and marine processes. Obvious manifestations of El Nino in the eastern Pacific are anomalous warming of the sea; reduced upwelling; a marked decline in fisheries, and high rainfall with frequent flooding.The 1982/83 El Nino was exceptionally severe, and was probably the strongest warming of the equatorial Pacific Ocean to occur during this century. The warming was intense and spread over large parts of the Pacific Ocean and penetrated to greater depths than usual. Many eastern Pacific coral reefs that had exhibited uninterrupted growth for several hundred years until 1983 were devasted by the disturbance and are now in an erosional mode. Marine species were adversely affected. The consequent depletion of the plant food base resulted in significant reductions in stocks of fish, squid etc. This led to a mass migration and near-total reproductive failure of marine birds at Christmas Island.Emphasis in this volume is placed on disturbances to benthic communities; littoral populations; terrestrial communities and extratropical regions.
