This book was released on 2013-05-09 with total page 1037 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 185. Indian Ocean Biogeochemical Processes and Ecological Variability provides a synthesis of current knowledge on Indian Ocean biogeochemistry and ecology and an introduction to new concepts and topical paradigm challenges. It also reports on the development of more extensive/frequent observational capacity being deployed in the Indian Ocean. This represents the first collection of syntheses that emphasize a basin-wide perspective, and the contributing authors include some of the most esteemed oceanographers and Indian Ocean experts in the world. The volume is derived from invited plenary talks that were presented at the initial Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER) workshop held at the National Institute of Oceanography (NIO) in Goa, India, in October 2006. The volume discusses The overlying physical processes set by monsoonal forcing and how these control biological production and variability Nutrient cycling and limitation Pelagic carbon cycling and air-sea exchange Benthic biogeochemistry and ecology The impact of climate and human activities on biogeochemistry and ecosystems. The readership for this book will consist of academic and governmental researchers interested in exploring how oceanographic, atmospheric, and hydrological processes combine to establish the environmental setting that supports and drives the pelagic system and which are especially relevant to understanding the complex biogeochemical and ecological interactions in the Indian Ocean.

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.

This book was released on 2013-11-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The global ocean contains a massive reservoir (662±32 Pg C) of dissolved organic carbon (DOC), and its dynamics, particularly in the deepest zones, are only slowly being understood. DOC in the deep ocean is ubiquitously low in concentration (~35 to 48 [mu]mol kg-1) and aged (4000 to 6000 years), persisting for multiple meridional overturning circulation cycles. Deep waters relatively enriched in DOC form in the North Atlantic. They migrate to the Southern Ocean (SO) to mix with waters from Antarctic shelves and the deep Pacific and Indian Oceans, in turn forming the voluminous circumpolar waters. The latter ultimately feed back into the Atlantic, Pacific, and Indian basins as bottom and intermediate waters. The goal of this dissertation is to assess evidence for local versus remote processes in influencing the distribution of DOC in the deep ocean. We use both large-scale datasets and isotopic and molecular composition data to understand the dynamics of the DOC pool on a global scale, though with an emphasis on the southern hemisphere. Chapter 2 focuses on DOC in Antarctic shelf systems and Antarctic Bottom Water (AABW) formation; Chapter 3 looks at the mostly conservative behavior of DOC in the deep SO; Chapter 4 considers the radiocarbon content of DOC in the South Indian Ocean (SIO) to assess the age of DOC; and Chapter 5 looks at the radiocarbon and molecular composition of DOC in the far North Pacific. In Chapter 6, findings are summarized. One potential local source of DOC to the deep SO is export from Antarctic shelf systems. Antarctica's continental shelves generate the densest waters in the world ocean and are responsible for the formation of AABW. AABW has the potential to sequester carbon in the deep ocean for millennia. DOC enrichment in dense shelf waters (DSW) in the Ross Sea was quantified and the potential for DOC to be sequestered into AABW was assessed. Ross Sea DSW was enriched in DOC by ~7 [mu]mol kg-1 relative to the incoming source waters (initial conditions), primarily due to deep vertical mixing of DOC-enriched surface waters. The total DOC excess in DSW suggests that 4.0±0.6 Tg DOC y-1 is exported off the shelf. However, this exported fraction does not appear to persist in newly formed AABW and is likely remineralized, sequestering this carbon as TCO2 in the deep ocean. A test of the conservative behavior of DOC in the Southern Ocean was assessed by considering its transport within deep water masses (North Atlantic Deep Water (NADW), Indian Deep Water (IDW), and Pacific Deep Water (PDW)). Multiple approaches (multiple linear regression, mass transport, and mass balance calculations) were used with data from CLIVAR Repeat Hydrography sections to evaluate the system. DOC concentrations in the deep SO and CDW largely reflect the linear mixing of those several deep waters entering the system from the north. Mass balance suggests too that the relatively depleted DOC radiocarbon content in the deep SO is a conserved property, but limited radiocarbon profiles in the SIO prevent a full analysis of the conserved behavior of 14C age of DOC. Consequently, to further test for the conservative behavior of the 14C age of DOC in the SO, the 14C age of DOC in the SIO was assessed; these data complete a survey of ages in the major deep water masses entrained into the SO. Four profiles of the 14C content of DOC spanning the SIO were collected, ranging from the Polar Front (56oS) to the subtropics (29oS). Surface waters had bulk radiocarbon ages of ~4400 years at the Polar Front and ~2000 14C years in the subtropics. At depth, mean radiocarbon age of DOC in CDW was 5302±160 14C years, while that in IDW was significantly older at 5557±81 14C years. A high-salinity remnant of NADW intruding into the deep SIO had a distinctly younger radiocarbon age for DOC (~5100 14C years). Multiple linear regression of 14C ages was used to assess the transport of DOC in the SIO. These results additionally confirm the conservative behavior of DOC in the deep Southern Ocean. To assess how the conserved behavior of DOC can be related to the molecular composition of dissolved organic matter (DOM), the 14C age of DOC was coupled with DOM composition in PDW in the far deep North Pacific (FNP), where the ocean's oldest water masses are located. DOM in this region has an old radiocarbon age (~6400 years old) and an overall molecular composition comprised of intrinsically stable compounds with low reactivities. By correlating radiocarbon age with each molecular formulae in solid-phase extracted DOM, the majority of DOM in PDW was found to have low reactivity and slow removal rates, especially in comparison with the DOM composition from the deep North Atlantic. Overall, this dissertation uses large-scale biogeochemical distributions as well as isotopic and molecular composition techniques to show that DOC cycling in the deep SO and SIO are due to mixing. As Antarctic shelf systems do not export DOC to the deep SO, instead DOC distributions and 14C age of DOC in the SO are largely controlled by mixing of NADW, IDW, and PDW. In addition, the SIO exhibits 14C ages of DOC consistent with water mass transports into that basin. Finally, the degraded molecular characteristic and old age of PDW in the FNP suggests that DOM in that region is low in reactivity and has not been renewed for long timescales.

This book was released on 2008-04-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly. The second edition of this book provides a thorough, up-to-date examination of these methods of research. As part of the Ecological Methods and Concepts series which provides the latest information on experimental techniques in ecology, this book looks at a wide range of techniques that use natural abundance isotopes to: follow whole ecosystem element cycling understand processes of soil organic matter formation follow the movement of water in whole watersheds understand the effects of pollution in both terrestrial and aquatic environments study extreme systems such as hydrothermal vents follow migrating organisms In each case, the book explains the background to the methodology, looks at the underlying principles and assumptions, and outlines the potential limitations and pitfalls. Stable Isotopes in Ecology and Environmental Science is an ideal resource for both ecologists who are new to isotopic analysis, and more experienced isotope ecologists interested in innovative techniques and pioneering new uses.
