Available in PDF, EPUB and Kindle. Book excerpt: Iron and manganese were installed as state variables in a previously developed sediment diagenesis model. The comprehensive model now incorporates nutrients, oxygen and sulfide, and iron and manganese. The model was initially calibrated using long-term mesocosm data The mesocosms contained water and sediments removed from Narragansett Sound, an estuarine environment Validation of the model was conducted using in situ data from two freshwater systems, Onondaga Lake and Croton Reservoir.

Available in PDF, EPUB and Kindle. Book excerpt: Iron and manganese are installed as state variables in a previously developed benthic sediment model. Initial emphasis is placed on manganese because of availability of observations. Mass-balance and chemical equilibrium equations for manganese in benthic sediments are presented. The model is tested in steady-state and time-variable mode against observations collected in Long Island Sound and Narragansett Bay. The initial model captures seasonal trends in sediment manganese release, although the magnitude of seasonal variability is underestimated. Improvement of the model through representation of manganese carbonate solubility is recommended. Iron, Model, Manganese, Sediments.

Available in PDF, EPUB and Kindle. Book excerpt: A derivative of the Encyclopedia of Inland Waters, Biogeochemistry of Inland Waters examines the transformation, flux and cycling of chemical compounds in aquatic and terrestrial ecosystems, combining aspects of biology, ecology, geology, and chemistry. Because the articles are drawn from an encyclopedia, they are easily accessible to interested members of the public, such as conservationists and environmental decision makers. This derivative text describes biogeochemical cycles of organic and inorganic elements and compounds in freshwater ecosystems

Download or read book Muddy Coast Dynamics and Resource Management written by B.W. Flemming and published by Elsevier. This book was released on 2000-12-08 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Muddy coasts are land-sea transitional environments commonly found along low-energy shorelines which either receive large annual supplies of muddy sediments, or where unconsolidated muddy deposits are being eroded by wave action.In providing 21 case studies in different parts of the world this book provides an up-to-date review of the state of the art in muddy coast research. Issues dealing with hydrodynamics and suspended matter transport, erosion, deposition, and sediment budgets on tidal flats, primary production, nutrient fluxes and mineralization in lagoons are treated in a multi disciplinary manner. Most articles deal with issues which are of relevance with respect to global warming and future sea level rise.
Download or read book Chemical and Biogeochemical Processes at Methane and Other Cold Seeps written by Davide Oppo and published by Frontiers Media SA. This book was released on 2023-10-31 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is a strong climate-active gas, the concentration of which is rapidly increasing in the atmosphere. Vast methane reservoirs are hosted in seafloor sediments, both dissolved in pore fluids and trapped in gas hydrate. Cold seeps discharge significant amounts of this methane into the ocean. The rate of seabed methane discharge could be orders of magnitude higher than current estimates, creating considerable uncertainty. The extent of methane transfer from the seafloor to the water column and ultimately to the atmosphere is also uncertain. The seepage of methane and other hydrocarbons drives complex biogeochemical processes in marine sediments and the overlying water column. Seeps support chemosynthesis-based communities and impact the chemistry of the water column. Seeps may also play a critical role in ocean acidification and deoxygenation and can be geohazards, as well as a potential energy resource. Unraveling the complex and dynamic interactions and processes at marine seeps is crucial for our understanding of element cycling in the geo- and hydrosphere.

Book excerpt: Practical and provocative, Bioavailability reviews prevalent understanding of the physical-chemical-biological mechanisms that control the bioavailability of both organic and inorganic contaminants in aquatic environments. Discusses the complex issues that surround many regulatory issues Emphasizes the need to identify and control that portion of the total concentration that is biologically available and can cause adverse effects, i.e., "active" Examines the influence of dynamic factors, such as pH, alkalinity, and light on these mechanisms Addresses the subject of speciation for both organic and inorganic contaminants
Download or read book Sediment Diagenesis written by A. Parker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks. Detailed knowledge of the diagenetic textures, fabrics, and minerals, and a prediction of the regional diagenetic response, partly controls hydrocarbon recovery programmes. In other words, knowledge of the diagenesis can aid (or even control) conservation policy. Similarly, facies and diagenetic trends w.ithin basins can influence exploration policy. This volume incorporates the majority of the principal contributions given to the NATO Advanced Study Institute held in the University of Reading, U.K., from July 12th-25th, 1981, at which the major themes of carbonate and terrigenous clastic sediments were treated sequentially from deposition to deep burial. Eighty selected scientists from twelve NATO and three other countries participated in the Institute. The keynote addresses which acted as the touchstones for discussion are presented here in the expectation that they will stimulate a still wider audience. We gratefully acknowledge the award of a grant from the Scientific Affairs Division of NATO to run the Institute, and also the cooperation of the University of Reading. Mrs. D. M. Powell helped in many ways with the organisation, and also retyped the entire manuscript of this book. A. Parker B. lv.

Download or read book Ecological Microcosms written by Robert J. Beyers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Microcosms is a seminal work which reviews the expanding field of enclosed ecosystem research, and relates the results and models of microcosm studies to general concepts in ecology. Microcosms are miniaturized pieces of our biosphere, ranging from streams and lakes to terraria, agroecosystems, and waste systems. The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of environmental management and global stability. The authors have used the well-known thermodynamic approach of H.T. Odum and numerous computer simulations. The book also includes an evaluation of alternative mesocosm approaches for the support of humans in space, as well as appendices to aid in the teaching of environmental concepts using student-created microcosms. Ecological Microcosms will be of interest to ecologists, environmental engineers, policy makers and environmental managers, space scientists, and educators. Robert J. Beyers is a Professor of Biology at the University of South Alabama. Howard T. Odum is Graduate Research Professor of Environmental Engineering Sciences at the University of Florida, and was awarded, with Eugene Odum, the 1987 Crafoord Prize in the Biosciences.
