This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the basic concepts of ocean biogeochemistry is that of an ocean with extremely active boundary zones and separation boundaries of extensive biochemical interactions. The areas of these zones are characterized by a sharp decrease of element migration intensity and consequently the decrease in their concentrations gave the boundaries for the naming of the geochemical barriers (Perelman, 1972). For the purposes of biogeo chemistry the most important ones are the boundaries of separation between river-sea, ocean-atmosphere, and water-ground (Lisitzin, 1983). The most complicated of them is the river-sea boundary, where the biogeochemical processes are the most active and complicated (Monin and Romankevich, 1979, 1984). The necessity of studying organic matter in rivers, mouth regions and adjoining sea aquatories has been repeatedly pointed out by v.I. Vernadsky (1934, 1960) who noted both the importance of registration of solid and liquid run-off of rivers, coming into the sea, and "the quality and the character of those elements, which are washed-down into the sea", emphasizing that "wash-down of organic substances into the sea is of great value". The interest in studying organic matter in natural waters, including river and sea waters, has grown considerably over the last 30 years. During this period essential material was collected on the content and composition of organic matter in various types of river waters of the USSR, and this was published in papers by B.A Scopintzev, AD. Semenov, M.V.

This book was released on 2013-11-11 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: My work Geochemistry oj organic matter in the ocean first appeared in Russian in 1978. Since then much progress has been made in the exploration of various forms of organic matter in the ocean: dissolved, colloidal, organic matter sus pended in particles and that contained in bottom sediments and in interstitial waters. The appropriate evidence is found in hundreds of articles and several re view works, such as Andersen (1977), Biogeochimie de [a matiere organique a ['interjace eau-sedimentmarine (1980), Duursma and Dawson (1981). A great amount of new information has been obtained in the Soviet Union's scientific institutions on the composition and distribution in natural waters and bottom sediments of organic matter and its separate components playing a crucial role in the formation of the chemical and biological structure of the ocean and its productivity, in the biogeochemistry of the elements and geochemistry of organic matter in the Earth's sedimentary cover. The areas of exploration have expanded over the past four-and-a-half years to embrace many new, little-known regions, including the Arctic seas. In contrast to the three preceeding decades, the research has been focused on investigating the existing forms, the distribution and accumulation of organic matter in near continental oceanic zones between land and sea, and in river estuaries.

Download or read book Organic geochemistry of natural waters written by E.M. Thurman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written as a reference on organic substances in natural waters and as a supplementary text for graduate students in water chemistry. The chapters address five topics: amount, origin, nature, geochemistry, and characterization of organic carbon. Of these topics, the main themes are the amount and nature of dissolved organic carbon in natural waters (mainly fresh water, although seawater is briefly discussed). It is hoped that the reader is familiar with organic chemistry, but it is not necessary. The first part of the book is a general overview of the amount and general nature of dissolved organic carbon. Over the past 10 years there has been an exponential increase in knowledge on organic substances in water, which is the result of money directed toward the research of organic compounds, of new methods of analysis (such as gas chromatography and mass spectrometry), and most importantly, the result of more people working in this field. Because of this exponential increase in knowledge, there is a need to pull together and summarize the data that has accumulated from many disciplines over the last decade.

Available in PDF, EPUB and Kindle. Book excerpt: Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

Download or read book Geochemistry of Marine Sediments written by David J. Burdige and published by Princeton University Press. This book was released on 2020-08-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The processes occurring in surface marine sediments have a profound effect on the local and global cycling of many elements. This graduate text presents the fundamentals of marine sediment geochemistry by examining the complex chemical, biological, and physical processes that contribute to the conversion of these sediments to rock, a process known as early diagenesis. Research over the past three decades has uncovered the fact that the oxidation of organic matter deposited in sediment acts as a causative agent for many early diagenetic changes. Summarizing and discussing these findings and providing a much-needed update to Robert Berner's Early Diagenesis: A Theoretical Approach, David J. Burdige describes the ways to quantify geochemical processes in marine sediment. By doing so, he offers a deeper understanding of the cycling of elements such as carbon, nitrogen, and phosphorus, along with important metals such as iron and manganese. No other book presents such an in-depth look at marine sediment geochemistry. Including the most up-to-date research, a complete survey of the subject, explanatory text, and the most recent mathematical formulations that have contributed to our greater understanding of early diagenesis, Geochemistry of Marine Sediments will interest graduate students of geology, geochemistry, and oceanography, as well as the broader community of earth scientists. It is poised to become the standard text on the subject for years to come.

Download or read book Ecology of Humic Substances in Freshwaters written by Christian Steinberg and published by Springer Science & Business Media. This book was released on 2003-04-16 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.
Download or read book Chemistry of Marine Water and Sediments written by Antonio Gianguzza and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important processes on the Earth`s surface occur in the Ocean where materials and energy are primarily exchanged. In the case of marine chemistry different fields of chemistry from organic to inorganic as well as thermodynamics and biochemistry are involved. Analytical Chemistry is a very important tool for the quantification of biogeochemical processes by providing correct and even more sophisticated methodologies. These are often directly applied 'in situ', in order to detect trace and ultra-trace natural and anthropogenic substances. Kinetic and thermodynamic studies allow us to establish whether the process occurs. Once discovered it is then possible to build up general models for environmental systems. This book gathers many aspects with the aim of creating a general picture of the chemical processes occurring in the marine environment
