This book was released on 1971 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: To trace the effects of cultural eutrophication, one meter sediment cores were used to determine the history of calcareous and noncalcareous Wisconsin lakes. Cores were analyzed for carbon, phosphorus, calcium, magnesium, potassium, aluminum, iron, and manganese. Determinations of organic nitrogen, exchangeable ammonium and acid soluble phosphorus were made on selected sedimentary profiles. Recent sedimentation rates and identification of pre- and postcultural sediments were determined by ragweed pollen. Enrichment of phosphorus in postcultural Lake Mendota, Wisconsin, sediments are the effect of increased phosphorus supply from domestic sewage. Chemical stratigraphy of concentration-depth diagrams permit a qualitative evaluation of cultural activities. Potentialities and limitations of using recent lake sediments to evaluate eutrophication are discussed.

This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic chemistry is becoming both a rewarding and substantial area of inquiry and is drawing many prominent scientists to its fold. Its literature has changed from a compilation of compositional tables to studies of the chemical reactions occurring within the aquatic environments. But more than this is the recognition that human society in part is determining the nature of aquatic systems. Since rivers deliver to the world ocean most of its dissolved and particulate components, the interactions of these two sets of waters determine the vitality of our coastal waters. This significant vol ume provides not only an introduction to the dynamics of aquatic chem istries but also identifies those materials that jeopardize the resources of both the marine and fluvial domains. Its very title provides its emphasis but clearly not its breadth in considering natural processes. The book will be of great value to those environmental scientists who are dedicated to keeping the resources of the hydrosphere renewable. As the size of the world population becomes larger in the near future and as the uses of materials and energy show parallel increases, the rivers and oceans must be considered as a resource to accept some of the wastes of society. The ability of these waters and the sediments below them to accommodate wastes must be assessed continually. The key questions relate to the capacities of aqueous systems to carry one or more pollutants.

Book excerpt: This Workshop was organized to assess the status of knowledge on the behaviour of phosphorus in sediments and to define gaps and reassess research strategies, particularly with respect to prevalent methodology and future approach; and to define gaps and reassess research strategies for water management measures in aquatic ecosystems, especially in relation to the release of phosphorus from the sediments and its impact on the functioning of the whole system.

Download or read book A Eutrophic Lake written by Thomas D. Brock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Mendota has often been called "the most studied lake in the world. " Beginning in the "classic" period of limnology in the late 19th century and continuing through the present time, this lake has been the subject of a wide variety of studies. Although many of these studies have been published in accessible journals, a significant number have appeared in local monographs and reports, ephemeral documents, or poorly distributed journals. To date, there has been no attempt at a synthetic treatment ofthe vast amount of work that has been published. One intent of the present book is to present a com prehensive compilation of the major early studies on Lake Mendota and to examine how they impinge on important present-day biological questions. In addition, this book presents a summary of field and laboratory work carried out in my own laboratory over a period of about 6 years and shows where correlations with earlier work exist. The book should be ofinterest to limnologists desiring a ready reference to data and published papers on this important lake, to biogeochemists, ocean ographers, and low-temperature geochemists interested in lakes as model sys tems for global processes, and to lake managers interested in understanding short-term and long-term changes in lake systems. Although the major thrust ofthe present book is ecologicaland environmental, sufficient background has been presented on other aspects ofLake Mendota's limnology so that the book should also be useful to nonbiologists.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 9: Regional and Specific Deposits focuses on the processes, methodologies, principles, and approaches involved in the identification of regional and specific ore deposits. The selection first elaborates on the timing of mineralization in stratiform copper deposits, oolitic iron formations, and metalliferous deep-sea sediments. Discussions focus on marine distribution and nature of surface and near-surface deposits, structural setting and associated deposits, principal types of deep-sea metal-enriched sediments, chronological development of oolitic-inland-sea iron formation, and complementary sources and transport mechanisms. The text then tackles heavy-metal accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits. Topics include lithological associations, oxidation and supergene alteration of ores, temporal and tectonic setting, dissolved metal concentrations in large freshwater systems, and transport phases of heavy metals in river water. The publication examines strata-bound tin deposits, geology of the Pine Point lead-zinc district, and genesis of the Rammelsberg ore deposit near Goslar/Upper Harz in the Federal Republic of Germany. The selection is a valuable reference for researchers wanting to explore ore deposits.
