Presented by some of the world's leading scientists, this revised edition reports on the major advances in this area and includes new chapters covering the role of DOM in ancient ocean carbon cycles, the long term stability of marine DOM, the biophysical dynamics of DOM, fluvial DOM qualities and fate, and the Mediterranean Sea. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, is an extremely useful resource that helps people interested in the largest pool of active carbon on the planet (DOC) get a firm grounding on the general paradigms and many of the relevant references on this topic. - Features up-to-date knowledge of DOM, including five new chapters - The only published work to synthesize recent research on dissolved organic carbon in the Mediterranean Sea - Includes chapters that address inputs from freshwater terrestrial DOM
Book Synopsis Applications of Fluorescence Spectroscopy to Environmental Chemistry by : Sarah A. Green
Download or read book Applications of Fluorescence Spectroscopy to Environmental Chemistry written by Sarah A. Green and published by . This book was released on 1992 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis consists of three parts. The first is a photophysical study of the mechanism of fluorescence quenching by stable nitroxyl radicals, which are becoming an important analytical tool for the study of reactive transients in surface waters (1, 2). In part two, quenching of dissolved organic matter (DOM) fluorescence by nitroxides is employed to investigate the electrostatic propertie~ of DOM in aqueous solution, with the goal of elucidating the apparent ionic strength and pH dependence of metal-fulvic acid binding constants. In part three, the intrinsic optical properties (absorbance, fluorescence, and fluorescence efficiency) of DOM are examined in a coastal region to understand how these properties vary with source. age and sunlight exposure time. Nitroxide-fluorophore adducts were employed to investigate the mechanism by which nitroxyl radicals quench fluorescence (3). Fluorescence quantum yields and lifetimes were measured for a series of adducts, and quenching rates were shown to be quite high (kq~108-1010 s-1), even at distances of ~12 A. Forster or Dexter energy transfer mechanisms are unable to account for the observed rates and lack of solvent dependence in quenching. An excellent correlation is observed between kq and the non-radiative relaxation rate. These results confirm that nitroxyl radicals are very non-selective in their quenching abilities, and suggest that the best analytical probe adducts will include a fluorophore with an appreciable non-radiative relaxation rate. Diffusional quenching by charged and neutral nitroxides was employed to explore the electrostatic properties of fulvic (FA) and humic (HA) acids. Cationic nitroxides were found to be up to 16 times more effective than neutral analogues in quenching the fluorescence of humic materials. This result is attributed to the enhanced coulombic attraction of cations to the anionic FA or HA surface, and is interpreted as an estimate of surface electrostatic potential. Reduction of molecular charge at low pH and shielding of charge at high ionic strength (I) produced diminished enhancements. consistent with this interpretation. The potential was found to be particularly sensitive to ionic strength. suggesting that this electrostatic effect should be of particular importance in transition zones. such as estuaries, where I increases from

Book Synopsis Organic Substances and Sediments in Water by : Robert A. Baker
Download or read book Organic Substances and Sediments in Water written by Robert A. Baker and published by CRC Press. This book was released on 1991-08-19 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fate and transport of natural and anthropogenic sediment-borne organic contaminants is a critical environmental issue and complex processes are involved that until now have been poorly defined. Organic Substances and Sediments in Water is a three-volume book that provides the best information available regarding the many interdisciplinary factors affecting organic substances associated with particulates in water. Topics discussed include absorption and transport of contaminants associated with particles; interfacial processes affecting fate and transport of organic substances associated with particles; the release of contaminants in receiving water bodies; water treatment; the role of biological factors in the fate and transport of organic contaminants in aqueous systems; development of biotransformation in natural and anthropogenic systems; the use of organic contaminant and sediment chemicals; biological and physical data to refine models to be used by resource managers; and chemical and biological processes that affect the fate and transport of organic constituents and determine degradation of contaminants and uptake in plants. This will be an important reference for environmental chemists, environmental engineers, environmental biologists, water treatment and natural system modelers, and soils scientists.
Book Synopsis Photobiogeochemistry of Organic Matter by : Khan M.G. Mostofa
Download or read book Photobiogeochemistry of Organic Matter written by Khan M.G. Mostofa and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 919 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoinduced processes, caused by natural sunlight, are key functions for sustaining all living organisms through production and transformation of organic matter (OM) in the biosphere. Production of hydrogen peroxide (H2O2) from OM is a primary step of photoinduced processes, because H2O2 acts as strong reductant and oxidant. It is potentially important in many aquatic reactions, also in association with photosynthesis. Allochthonous and autochthonous dissolved organic matter (DOM) can be involved into several photoinduced or biological processes. DOM subsequently undergoes several physical, chemical, photoinduced and biological processes, which can be affected by global warming. This book is uniquely structured to overview some vital issues, such as: DOM; H2O2 and ROOH; HO•; Degradation of DOM; CDOM, FDOM; Photosynthesis; Chlorophyll; Metal complexation, and Global warming, as well as their mutual interrelationships, based on updated scientific results.

Book Synopsis Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms by : Babin, Marcel
Download or read book Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
Book Synopsis Chlorophyll a Fluorescence in Aquatic Sciences: Methods and Applications by : David J. Suggett
Download or read book Chlorophyll a Fluorescence in Aquatic Sciences: Methods and Applications written by David J. Suggett and published by Springer Science & Business Media. This book was released on 2010-08-23 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of variable chlorophyll fluorescence have revolutionised global research of photosynthetic bacteria, algae and plants and in turn assessment of the status of aquatic ecosystems, a success that has partly been facilitated by the widespread commercialisation of a suite of chlorophyll fluorometers designed for almost every application in lakes, rivers and oceans. Numerous publications have been produced as researchers and assessors have simultaneously sought to optimise protocols and practices for key organisms or water bodies; however, such parallel efforts have led to difficulties in reconciling processes and patterns across the aquatic sciences. This book follows on from the first international conference on “chlorophyll fluorescence in the aquatic sciences” (AQUAFLUO 2007): to bridge the gaps between the concept, measurement and application of chlorophyll fluorescence through the synthesis and integration of current knowledge from leading researchers and assessors as well as instrument manufacturers.
Book Synopsis Methods of Seawater Analysis by : Klaus Grasshoff
Download or read book Methods of Seawater Analysis written by Klaus Grasshoff and published by John Wiley & Sons. This book was released on 2009-07-30 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.
