Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Perspectives on Integrated Coastal Zone Management written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: All coastal areas are facing a growing range of stresses and shocks, the scale of which now poses threats to the resilience of both human and environmental coastal systems. Responsible agencies are seeking better ways of managing the causes and consequences of the environmental change process in coastal zones. This volume discusses the basic principles underpinning a more integrated approach to coastal management and highlights the obstacles that may be met in practice in both developed and developing countries. Successful strategies will have to encompass all the elements of management, from planning and design through financing and implementation, as highlighted in this book.
Download or read book Marine Geochemistry written by Roy Chester and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Marine Geochemistry received strongcritical acclaim, and the reviews included the comments that it'provides a benchmark in the field' and 'is clearly recognizable asa standard text for years to come'. Marine Geochemistry offers a fully comprehensive andintegrated treatment of the chemistry of the oceans, theirsediments and biota. It addresses the fundamental question 'How dothe oceans work as a chemical system?' by capitalizing on thesignificant advances in understanding oceanic processes made overthe past three decades. These advances have been facilitated byimproved sampling and analytical techniques, a better understandingof theoretical concepts and the instigation of large-sizedinternational oceanographic programs. Designed for use as a text, the book treats the oceans as a'unified system' in which material stored in the sea water, thesediment and the rock reservoirs interacts to control thecomposition of sea water itself. Part I covers the transport ofmaterial to the oceans via rivers, the atmosphere and hydrothermalsystems, and discusses their relative flux magnitudes. Part IIconsiders the oceans as a reservoir, introducing water-columnparameters before discussing water-column fluxes and the benthicboundary layer. Part III is devoted to the sediment reservoir. Thetopics covered include diagenesis, the major components of thesediments, and the processes controlling the geochemistry ofoceanic deposit, which are discussed in terms of sediment-formingsignals. Part IV offers an overview and synthesis of the integratedmarine geochemical system. Since the publication of the first edition, there have beenfurther significant advances in several areas of the subject. Therevised text of this edition accommodates these advances, whilestill retaining the emphasis on identifying key processes operatingwithin a 'unified ocean.' Special attention has been paid tofundamental conceptual changes, such as those related to tracemetal speciation in sea water, hydrothermal activity, carbondioxide and the importance of the oceans in world climate change,the transport of particulate material to the interior of the ocean,primary production and iron limitation, colloids, and thepreservation/destruction of organic matter in marine sediments. Intermediate and advanced students with interests in chemicaloceanography, marine geochemistry, marine biology and environmentalchemistry will welcome this revised comprehensive text. Otherstudents in the broader field of earth sciences will find it to bean essential reference source dealing with the interaction betweenthe atmosphere, the ocean and the solid earth. Incorporates all significant recent advances in thefield. 'Unified system' approach to ocean chemistry. Emphasises geological contexts, e.g. sediment diagenesis.

Download or read book Evaluating and Monitoring the Health of Large Scale Ecosystems written by David J. Rapport and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem health offers a fresh perspective on the management of natural resources and the environment. While some of the root concepts can surely be traced back to Aldo Leopold and even earlier, it is only in the recent decade that a substantial body of work has emerged on this topic. There is no question that a novel approach which is by its nature cross disciplinary, bridging the health and biological sciences, will initially raise a number of questions particularly pertaining to the use of metaphors and the validity of the analogy. This volume however goes beyond merely the philosophical dimensions of the subject by covering a number of case studies which have given rise to the development of promising quantitative methods for diagnosis and rehabilitation of ecosystems under stress. The focus of most studies is on regional ecosystems i.e. ecosystems of large scale. As such, the methods and approaches should have wide appeal to government agencies charged with the responsibility of sustainable development of regional ecosystems and natural resources. Health is one of those difficult concepts that everyone thinks they can define, until they come to try. We all have personal knowledge about health and illness and this makes the ecosystem analogy so potentially powerful. Yet it is also clear that the uncritical application of the concept could lead to overly simplistic approaches to analysis and management of ecosystem health.

Download or read book Pollution of the North Sea written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 753 pages. Available in PDF, EPUB and Kindle. Book excerpt: This preface is being written at a time of exceptional public interest in the North Sea, following media head lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels. These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen tury. The growth of cities and introduction of sewer sys tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con tributes to the global input of pollutants to the world's oceans. The major part of the pollutants accumulate in the North Sea and are incorporated in the bottom sediments. Although they are "out of sight", they should not be "out of mind".

Book excerpt: The concepts and concerns regarding the global effects of a continued increase in the atmospheric concentrations of greenhouse gases have enjoyed a high visibility in newspapers and scientific journals. This concern is now being translated into big-science projects. These international projects aim to understand better the processes of climate and ecosystem changes and impacts and are being designed under the aegis of the World Climate Research Programme and the International Geosphere-Biosphere Programme. Biological and climatic systems are intertwined in processes leading to impacts and feedbacks and so it has emerged that climatologists, atmospheric scientists, terrestrial and marine ecologists must collaborate in research programmes, else the bases of their future projections are incomplete. This special volume of Advances in Ecological Research brings together eight papers which propose and demonstrate the two major components of current climate change research, future prediction and interdisciplinary approach.

Download or read book Facets of Modern Biogeochemistry written by Egon T. Degens and published by Springer. This book was released on 1990-02-20 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists who have had the opportunity of being associated with Professor Egon T. Degens, to whom this Festschrift is devoted, have been influenced by his ideas on subjects as varied as: extraterrestrial organic matter, origin of life, evolution of organisms, isotope biogeochemistry down to more imminent ones such as the carbon cycle and its implications on climate. This variety is also reflected in the papers in the present volume contributed by colleagues who have known Egon or have worked with him. Egon Theodor Degens was born on April 16, 1928 at Inden, Germany and had his education in Bonn and Wiirzburg. After a stint at the Pennsylvania State University he returned to Wiirzburg to help set up one of the first organic geochemistry laboratories in the world. This laboratory was the breeding ground for some of the eminent organic geochemists at work today. Later, he joined the California Institute of Technology and began his work on stable carbon isotopes, and later on biogeochemical compounds in natural waters. From California he moved on to the east coast, which led to yet another productive phase at the Woods Hole Oceanographic Institution. He was instrumental in the pioneering work carried out by the Woods Hole scientists in the Black Sea which is the largest anoxic basin in the world, and in the Red Sea where the first hydrothermal ore deposits on the seafloor were discovered.

Download or read book Quantitative Distribution of Suspended Matter in the Surface Water of the North Indian Ocean written by E. I. Gordeev and published by . This book was released on 1967 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of distribution and composition of suspended matter in oceans is associated with the solution of problems concerning the sedimentation in oceans. The suspended matter is also significant when solving problems of geo- and hydro-chemistry, biological productivity, physical properties of sea water, etc. The distribution and composition of suspended matter in oceans is closely associated with many factors--namely, with hydrodynamical conditions, morphology of ocean bottom, characteristics of development and distribution of plankton as well as with physical-geographical characteristics of the basins themselves and the surrounding land areas. The study of suspended matter in the Indian Ocean was conducted during the four cruises of the Ob'. The collection of suspended matter in the Indian Ocean during the 33rd cruise of Vityaz' was carried on from October 1960 to April 1961 by using two methods: semi-permeable membrane ultrafiltration of particles larger than 0.7 microns with the application of membrane filters no. 3, and separation with the use of highly efficient industrial separators.
