Download or read book Tracking Environmental Change Using Lake Sediments written by John P. Smol and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.

Download or read book Use of Proxies in Paleoceanography written by Gerhard Fischer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoceanographic proxies provide infonnation for reconstructions of the past, including climate changes, global and regional oceanography, and the cycles of biochemical components in the ocean. These prox ies are measurable descriptors for desired but unobservable environmental variables such as tempera ture, salinity, primary productivity, nutrient content, or surface-water carbon dioxide concentrations. The proxies are employed in a manner analogous to oceanographic methods. The water masses are first characterized according to their specific physical and chemical properties, and then related to particular assemblages of certain organisms or to particular element or isotope distributions. We have a long-standing series of proven proxies available. Marine microfossil assemblages, for instance, are employed to reconstruct surface-water temperatures. The calcareous shells of planktonic and benthic microorgan isms contain a wealth of paleoceanographic information in their isotopic and elemental compositions. Stable oxygen isotope measurements are used to detennine ice volume, and MglCa ratios are related to water temperatures, to cite a few examples. Organic material may also provide valuable infonnation, e. g. , about past productivity conditions. Studying the stable carbon isotope composition of bulk organic matter or individual marine organic components may provide a measure of past surface-water CO 2 conditions within the bounds of certain assumptions. Within the scope of paleoceanographic investigations, the existing proxies are continuously evolving and improving, while new proxies are being studied and developed. The methodology is improved by analysis of samples from the water column and surface sediments, and through laboratory experiments.
Download or read book Coastal Upwelling Its Sediment Record written by Erwin Suess and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: NATO Advanced Research Institutes are designed to explore unre solved problems. By focusing complementary expertise from various disciplines onto one unifying theme, they approach old problems in new ways. In line with this goal of the NATO Science Committee, and with substantial support from the u.s. Office of Naval Research and the Seabed Assessment Program of the U. S. National Science Founda tion, such a Research Institute on the theme of Coastal Upwelling and Its Sediment Record was held september 1-4, 1981, in Vilamoura, Portugal. The theme implies a modification of uniformitarian thinking in earth science. Expectations were directed not so much towards find ing the key to the past as towards exploring the limits of interpret ing the past based on present upwelling oceanography. Coastal up welling and its imprint on sediments are particularly well-suited for such a scientific inquiry. The oceanic processes and conditions characteristic of upwelling are well understood and are a well packaged representation of ocean science that are familiar to geolo gists, just as the magnitude of bioproduction and sedimentation in upwelling regimes --among other biological and geological processes- have made oceanographers realize that the bottom has a feedback role for their models.

Download or read book The Biogeochemical Cycle of Silicon in the Ocean written by Bernard Quéguiner and published by John Wiley & Sons. This book was released on 2016-06-16 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the biogeochemical dynamics of marine ecosystems, silicon is a major element whose role has, for a long time, been underestimated. It is however indispensable to the activity of several biomineralizing marine organisms, some of which play an essential role in the biological pump of oceanic carbon. This book presents notions indispensable to the knowledge on the silicon biogeochemical cycle in ocean systems, first of all describing the main quantitative analysis techniques and examination of the major organisms involved in the cycle. The author then moves on to study the most up-to-date processes to control the use of silicon and its regeneration in natural conditions, before mentioning the central role played by this original element in the control of all the biogeochemical cycles in the global ocean. The available information finally enables the global biogeochemical budget of silicon in the marine environment to be quantified.

Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable re sources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication in the transitional marine coastal waters has increased dramatically in many parts of the world, and this evolution has shifted attention to the anthropogenic factor. The problem has become the theme of many conferences and workshops, as well as being given priority in international organizations. This volume has been brought about by the desire to assess both our scientific understanding as well as the means and technologies available to combat the problem of marine coastal eutrophication. It discusses the results of research and surveillance programmes carried out in the last ...

This book was released on 2013-06-29 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: "How can we increase the production and harvest of living marine resources in the new millennium? Bridging potentials and environmental constraints". This was the theme of the 1st Maricult Conference arranged in Trondheim, Norway in June 2000 in connection with termination of the Norwegian research programme Maricult (1996-2000; www.maricult.org). The intention for the conference was not only to present a state of the art overview of the research conducted as part of the programme, but also to describe other experiences and to discuss the ideas and the scientific status of the programme with the international scientific community. A total of 50 oral communications and 8 posters were presented at the conference. Sixteen of them are included in the present volume. They deal with such topics as strategies for improving marine harvest, underlying mechanisms for marine productivity, new concepts of mariculture with emphasize on mussels, and nutrient supply and environmental impact.
