Completely revised and updated for its second edition, this volume belongs to the Open University series on oceanography. It is designed so that it can be read on its own or studied as part of the Open University third-level course, S330 Oceanography. The book begins by describing the characteristics of waves and tides, and their behaviour in shallow water. After outlining the sources of sediment supply to the oceans, some theoretical aspects of sediment movement and deposition by currents are considered. After looking at wave action in the littoral zone, the interplay of tidal currents, river flow and wave action in estuaries and deltas are explored. The final chapter provides an overview of shelf processes. This is a vital book for all oceanography undergraduate students worldwide. Easy to use question and answer format Full colour illustrations throughout 35-40% revised and extended from 1st edition
The text begins by describing waves, their measurement and characteristics, their behaviour in shallow water, and unusual waves. Next, mainly theoretical aspects are considered of sediment movement and deposition by currents, before discussing wave action in the littoral zone, tidal current action on tidal flat and in estuaries, and the interaction of waves, tides, and river flow in deltas. Finally, we examine shelf-sea processes, including an outline of their mineral resources.

Constituting more than 70 percent of Earths surface, the worlds oceans are so vast as to remain something of an enigma to this day. Navigating these imposing seas and unlocking their secrets is the calling of oceanographers. Their research helps determine what climatic, geologic, and chemical impact oceans have on a variety of organisms. In spite of their magnitude and might, the worlds oceans are not immune to the effects of adverse human activity, such as pollution. This volume surveys this huge, but fragile, ecosystem and the individuals who help fight for the preservation of this vital resource that has critical significance to all earthly life.

In recent years, research on acoustic remote sensing of the ocean has evolved considerably, especially in studying complex physical and biological processes in shallow water environments. To review the state of the art, an international workshop was held at Carvoeiro, Portugal, in March 1999, bringing together leading international researchers in the field. In contrast to much of the recent theoretical work, emphasis was placed on the experimental validation of the techniques. This volume, based on presentations at this workshop, summarizes a range of diverse and innovative applications. The invited contributions explore the use of acoustics to measure bottom properties and morphology, as well as to probe buried objects within the sediment. Within the water column, sound is applied to imaging of oceanographic features such as currents and tides or monitoring of marine life. Another key theme is the use of sound to solve geometric inverse problems for precise tracking of undersea vehicles. Audience: This volume should be useful both to the novice seeking an introduction to the field and to advanced researchers interested in the latest developments in acoustic sensing of the ocean environment. The workshop was sponsored by the Fundação para a Ciêcia e a Tecnologia (Portuguese Foundation for Science and Technology).
Seawater: Its Composition, Properties and Behaviour provides a comprehensive introduction to marine science. This book is divided into seven chapters. Chapter 1 summarizes the special properties of water and the role of the oceans in the hydrological cycle. The distribution of temperature and salinity in the oceans and their combined influence on density, stability, and vertical water movements are discussed in Chapters 2 to 4. The fifth chapter describes the behavior of light and sound in seawater and provides examples of the application of acoustics to oceanography. Chapter 6 examines the composition and behavior of the dissolved constituents of seawater, covering minor and trace constituents and major ions, as well as dissolved gases and biologically important nutrients. Residence times, speciation, and carbonate equilibria are also deliberated. The last chapter provides a short review of ideas about the history of seawater, involvement of the oceans in global cycles, and their relationship to climatic change. This publication is beneficial to oceanographers and marine biologists, including students that are interested in marine science.
This is an invaluable textbook, prepared by the Open University team and designed so that it can be read on its own or as part of the OU course. This second edition has been fully revised and updated including new colour illustrations increasing the striking spread of full colour diagrams throughout the book. The clarity of the text has been improved, providing comprehensive coverage of the evolution of ocean basins and their structure in a clear, concise manner aimed specifically at the student market. In this second edition the technological advances in fields as diverse as: - deep-towed instruments for `sniffing' hydrothermal plumes - mapping the sea-floor by sophisticated sonar techniques - three-dimensional imaging of crustal structure by seismic tomography - the use of satellites for navigation, and for making precise measurements of the height of the sea-surface The first chapters describe the processes that shape the ocean basins, determine the structure and composition of oceanic crust and control the major features of continental margins. How the 'hot springs' of the oceanic ridges cycle chemical elements between seawater and oceanic crust is then explored. Sediment distributions are examined next, to demonstrate how sediments can preserve a record of past climatic and sea-level changes. Finally, the role of the oceans as an integral part of global chemical changes is reviewed. High quality full colour diagrams Substantial chapter summaries ideal for revision Answers, hints and notes for questions at back of the book
This second edition retains the general structure of the first edition, but has been updated in the light of recent oceanographic research, and improved as a teaching text on the basis of feedback from past students and other readers. Notable additions include new sections addressing the topic of numerical modelling, and more discussion of natural oscillations in the ocean-atmosphere system (previously confined to the El Niño phenomenon). In particular, the Chapter on the North Atlantic now includes a discussion of the North Atlantic Oscillation, as well as of the Great Salinity Anomaly. In the final Chapter, treatment of water mass formation has been updated to reflect recent ideas about the processes involved and how they relate to climatic change over different time-scales, from decades to millennia.

In diesem Buch wird einerseits die spannende Entdeckung der Stratosphäre selbst und verschiedener unerwarteter Phänomene in der Stratosphäre beschrieben: ein bemannter Ballonflug im Jahr 1901 bis in 11 km Höhe; eine Expedition zum Victoriasee im Jahr 1908; die Entdeckung der Ozonschicht um 1930, des "Berliner Phänomens" im Jahr 1952, des Einflusses von Vulkaneruptionen im Jahr 1982, des Ozonlochs im Jahr 1985 und des Einflusses der Sonnenaktivität im Jahr 1987. Andererseits wird gezeigt, wie diese Erscheinungen miteinander verknüpft sind und wie sie anthropogene und natürliche Schwankungen in unserem Klimasystem verursachen. Am Beispiel der Stratosphäre soll das Buch zum Verständnis der Erforschung komplizierter Zusammenhänge in der Natur beitragen.
