Available in PDF, EPUB and Kindle. Book excerpt: The book presents results of recent projects in oceanography and marine geosciences (e.g. WOCE, JGOFS, PAGES, ODP) regarding present and past circulation in the South Atlantic. The objective of the book is to integrate results from both oceanographic and geological studies. As the connecting link between the Antarctic and the North Atlantic, the South Atlantic plays a crucial role with regard to the heat budget of the North Atlantic and to the biogeochemical budget of the global ocean. New results from studies of meridional water mass and heat transports are presented. The central theme of geological investigations is the reconstruction of current and productivity systems in the South Atlantic during the late Quaternary.
Download or read book From the Agulhas to the South Atlantic written by Deirdre Byrne and published by Universal-Publishers. This book was released on 2000-07-31 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Agulhas Retroflection transfers heat, salt and vorticity from the Indian Ocean to the South Atlantic. The transfer is accomplished by discrete meso-scale features and by the advection of a water column of mixed Atlantic and Indian Ocean origins. The objectives of this thesis are to measure the strength of the Agulhas-South Atlantic (ASA) exchange and to develop a generalized method for the measurement of mass and thermohaline fluxes. First, ASA mass and energy fluxes are estimated by using sea surface height (SSH) anomalies from satellite altimetry to monitor Agulhas eddies, a significant component of ASA transport. ~20 eddies are tracked from SSH during 1986 - 1989. Six eddies/year are observed entering the South Atlantic; when combined with information from hydrography this suggests minimum annual ASA mass and energy fluxes of O(5x10^6) m^3/s and O(10^17) J. Next, the accuracy of altimetric tide models, critical to measurements of ASA fluxes using altimetry, is evaluated in the Agulhas region by a comparison with in situ bottom pressure (BP). The CSR 3.0 model accounts for 98.5% - 99.4% of the variance in bottom pressure at four locations, with maximum discrepancies between model and in situ tides reaching 6.5 cm. In Enhanced Thermohaline Transport Analysis (ETTA), developed herein, vertically averaged thermohaline transport coefficients are parameterized as functions of SSH and acoustic travel time (tau). These quantities, which can be directly measured, are then used as proxies to determine mass and thermohaline fluxes from time-series of altimetric SSH and tau from inverted echo sounder moorings. Using ETTA, the 1992 - 1993 baroclinic-barotropic ASA fluxes through a moored array at 30S (2E - 17E) are estimated at O(14.5x10^6) m^3/s, O(15x10^20) J and O(83x10^12) kg salt per annum. Meso-scale eddies accomplish at least 18% of the transport. Lastly, ETTA is combined with the Gravest Empirical Mode (GEM) technique to create continuous parameterizations of temperature and salinity fields with pressure, tau and SSH. Thus tau and SSH become proxies for vertically resolved thermohaline profiles. With data from the Caribbean region, GEM-ETTA is shown to have the potential to resolve inter-ocean mass and thermohaline fluxes with time and depth.

Download or read book Ocean Biogeochemical Dynamics written by Jorge L. Sarmiento and published by Princeton University Press. This book was released on 2013-07-17 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean Biogeochemical Dynamics provides a broad theoretical framework upon which graduate students and upper-level undergraduates can formulate an understanding of the processes that control the mean concentration and distribution of biologically utilized elements and compounds in the ocean. Though it is written as a textbook, it will also be of interest to more advanced scientists as a wide-ranging synthesis of our present understanding of ocean biogeochemical processes. The first two chapters of the book provide an introductory overview of biogeochemical and physical oceanography. The next four chapters concentrate on processes at the air-sea interface, the production of organic matter in the upper ocean, the remineralization of organic matter in the water column, and the processing of organic matter in the sediments. The focus of these chapters is on analyzing the cycles of organic carbon, oxygen, and nutrients. The next three chapters round out the authors' coverage of ocean biogeochemical cycles with discussions of silica, dissolved inorganic carbon and alkalinity, and CaCO3. The final chapter discusses applications of ocean biogeochemistry to our understanding of the role of the ocean carbon cycle in interannual to decadal variability, paleoclimatology, and the anthropogenic carbon budget. The problem sets included at the end of each chapter encourage students to ask critical questions in this exciting new field. While much of the approach is mathematical, the math is at a level that should be accessible to students with a year or two of college level mathematics and/or physics.

Download or read book Environmental Radionuclides written by Klaus Froehlich and published by Elsevier. This book was released on 2009-09-23 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Radionuclides presents a state-of-the-art summary of knowledge on the use of radionuclides to study processes and systems in the continental part of the Earth's environment. It is conceived as a companion to the two volumes of this series, which deal with isotopes as tracers in the marine environment (Livingston, Marine Radioactivity) and with the radioecology of natural and man-made terrestrial systems (Shaw, Radioactivity in Terrestrial Ecosystems). Although the book focuses on natural and anthropogenic radionuclides (radioactive isotopes), it also refers to stable environmental isotopes, which in a variety of applications, especially in hydrology and climatology, have to be consulted to evaluate radionuclide measurements in terms of the ages of groundwater and climate archives, respectively. The basic principles underlying the various applications of natural and anthropogenic radionuclides in environmental studies are described in the first part of the book. The book covers the two major groups of applications: the use of radionuclides as tracers for studying transport and mixing processes: and as time markers to address problems of the dynamics of such systems, manifested commonly as the so-called residence time in these systems. The applications range from atmospheric pollution studies, via water resource assessments to contributions to global climate change investigation. The third part of the book addresses new challenges in the development of new methodological approaches, including analytical methods and fields of applications. - A state-of-the-art summary of knowledge on the use of radionuclides - Conceived as a companion to the two volumes of this series, which deal with isotopes as tracers
Download or read book Handbook of Environmental Isotope Geochemistry written by Mark Baskaran and published by Springer Science & Business Media. This book was released on 2011-10-13 with total page 944 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of radioactive and stable isotopes have revolutionized our understanding of the Earth and near-earth surface processes. The utility of the isotopes are ever-increasing and our sole focus is to bring out the applications of these isotopes as tracers and chronometers to a wider audience so that they can be used as powerful tools to solve environmental problems. New developments in this field remain mostly in peer-reviewed journal articles and hence our goal is to synthesize these findings for easy reference for students, faculty, regulators in governmental and non-governmental agencies, and environmental companies. While this volume maintains its rigor in terms of its depth of knowledge and quantitative information, it contains the breadth needed for wide variety problems and applications in the environmental sciences. This volume presents all of the newer and older applications of isotopes pertaining to the environmental problems in one place that is readily accessible to readers. This book not only has the depth and rigor that is needed for academia, but it has the breadth and case studies to illustrate the utility of the isotopes in a wide variety of environments (atmosphere, oceans, lakes, rivers and streams, terrestrial environments, and sub-surface environments) and serves a large audience, from students and researchers, regulators in federal, state and local governments, and environmental companies.
