Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. A compilation of the most recent research. It examines a wide range of factors affecting sediments as part of a multi-disciplinary investigation, including studies of sedimentology, geochemistry, physical oceanography, and benthic biology. The Amazon River discharges enormous amounts of particulate and dissolved material to the continental shelf. Knowledge about the fate of this material is relevant to understanding sedimentary processes at the interface between major rivers and the ocean and to interpreting similar shelf environments preserved in the stratigraphic record. The uniqueness of this volume results from the multi-disciplinary and interactive nature of the research, and from the major importance of the Amazon dispersal system.

Available in PDF, EPUB and Kindle. Book excerpt: With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.

Download or read book Sediment Transport and Distribution Over Continental Shelves written by Laura Lorenzoni and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this dissertation was to understand lithogenic suspended sediment transport mechanisms and distribution in two river-influenced margins: The Cariaco Basin, Venezuela, and the Amazon Shelf, Brazil. Lithogenic sediment input in the Cariaco Basin is controlled by small mountainous rivers (SMR), while in the Amazon Shelf it is dominated by the Amazon River, the largest river in the world in terms of freshwater discharge ([H stroke]20[percnt] of global riverine discharge). Optical transmissometer measurements were coupled with particulate organic matter (POM) observations to understand changes in the geochemical composition of suspended sediment and spatial/temporal distributions over the two regions of interest. In the Cariaco Basin sampling was conducted during the rainy seasons of September 2003, 2006 and 2008, and during the upwelling period (dry season) of 2009. Our results suggest that bottom nepheloid layers (BNL) originating at the mouth of the SMR discharging into the Cariaco Basin are a major delivery mechanism of terrigenous sediments to the basin's interior year-round. Intermediate nepheloid layers (INL) were also observed near the shelf break ([H stroke]100m) and appear to effectively carry terrigenous material laterally from the shelf to deep waters, thereby providing a plausible supply mechanism of the terrestrial material observed in sediment traps, deployed>70 km offshore as part of the CARIACO Ocean Time-Series. These findings highlight the importance of small, local rivers in the Cariaco Basin as sources of terrestrial material. Indeed, the low isotopic composition of particulate organic carbon ([delta]13Corg, [H stroke]-30 - -24 [89]) carried by the BNL suggests that this material was continentally derived. BNL [delta]13Corg also changed with season, indicating that the geochemical composition of BNL reflects particle source.

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 Carbonate Clastic Transitions written by Laurence (Hy) Doyle and published by Elsevier. This book was released on 1987-12-01 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years, the field of sedimentology has become subdivided into various specialities. Two of the largest groups are those who study clastic rocks and those who study carbonates. There is little communication between the two: journals appear which are exclusively devoted to one or the other, and research conferences tend to be mutually exclusive. On the other hand, rocks themselves cannot be "pigeon-holed" in this way - the facies change from clastic to carbonate both laterally and through time. This volume stems from the editors' observations of such changes in the Gulf of Mexico and their realization that these geologically important transitions were being largely ignored because of professional compartmentilization.The book opens with a chapter which gives an overview of the whole picture of global patterns of carbonate and clastic sedimentation. It then proceeds to a discussion of sedimentary models of siliciclastic deposits and coral reef relationships. The rest of the book comprises eight case studies on carbonate-clastic transitions, and a final chapter on control of carbonate-clastic sedimentation systems by baroclinic coastal currents.The aim of the book is to emphasize that clastic and carbonate sedimentation are not separate but part of a continuum - a transition which needs to be more thoroughly investigated and better understood. The excellent research papers presented here will undoubtedly help to achieve this goal.
