Available in PDF, EPUB and Kindle. Book excerpt: Over 10 years have passed since RANKAMA'S second book, Progress in Isotope Geology, surveyed the literature on isotope abundance deter minations. In the meantime the number of measurements and publi cations has increased enormously. Therefore, it seems necessary to summarize the knowledge in this field in the light of more recent developments. The title of this book was chosen because the whole field of radio active isotope geochemistry has been deliberately omitted. The book is divided into three parts. Section A gives the theory of isotope effects and the technical background, both aspects being discussed rather briefly. The author regrets some shortcomings in the introductory section, especially in the theoretical treatment of isotope fractionation, but he has been trained mainly in earth sciences rather than in physical chemistry. Section B gives a summary of the fractionation mechanisms affecting the most important elements - hydrogen, carbon, oxygen, and sulfur. Further, it surveys some other elements that have not yet been as thoroughly investigated. Section C surveys the most important results from a geological stand point. In some cases the opinions of different authors on the same sub ject are summarized without comment, because the field of stable isotope geology is growing so rapidly that a final answer cannot be given at the moment. It is obvious that in writing this book, which is of the survey type, the author could not rely only on his own experiments and experience.

Download or read book Time-series of Stable Isotopes in Dissolved Inorganic Carbon of Surface Seawater Near Bermuda and Hawaii written by Mariela Ke'o-lani Brooks and published by . This book was released on 2020 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 13C/12C ratio of stable carbon isotopes in dissolved inorganic carbon (DIC) can provide insight into carbon cycle variability and trends in the surface ocean. Measurements of [delta]13C-DIC when combined with DIC can be used to estimate anthropogenic carbon uptake and marine productivity and can contribute to our understanding of the role that the ocean plays in the global carbon cycle. This dissertation describes surface ocean time-series measurements near Bermuda (S-BATS) and Hawaii (HOT) of [delta]13C-DIC, DIC, and alkalinity (ALK) as a part of the Scripps Seawater Program, focusing on [delta]13C-DIC. Prior to this study, there was a hiatus in seawater [delta]13C-DIC measurements at Scripps, while samples continued to be collected and archived for future analysis. This dissertation details the resumption of these measurements along with the calibration and methodology used for Scripps measurements of [delta]13C-DIC. We quantify the calibration contributions to uncertainty in the context of consistency between newer and older measurements. In addition, we introduce and document the stability of three new seawater secondary standards, including a method based on CO2 in compressed N2 gas. In these time-series records of nearly three decades, we show that the long-term trends and seasonal cycles in sDIC and [delta]13C-DIC at both S-BATS and HOT are consistent with earlier studies and independent time-series records. From the full record we find no long-term changes in the seasonal cycle of sDIC, [delta]13C-DIC, or computed pCO2. Consistent to some earlier studies we find significant correlations at S-BATS with the North Atlantic Oscillation and at HOT with the Pacific Decadal Oscillation (PDO). We also find correlations at HOT that were not previously noted including the PDO with sea surface temperature and mixed layer depth (MLD), as well as El Nino Southern Oscillation (NINO3.4) with sDIC and MLD. Lastly, we use a combination of observations and CESM hindcast simulations to explore upper ocean carbon variability in subtropical gyres. This allows us to examine the time-series in a broader geographic context, showing coherent patterns of variability across the North Atlantic and North Pacific subtropical gyres and illustrating key differences in the controls of variability at BATS and HOT.

Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!

Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia is a complete and authoritative reference work for this rapidly evolving field. Over 200 international scientists, each experts in their specialties, have written over 330 separate topics on different aspects of geochemistry including geochemical thermodynamics and kinetics, isotope and organic geochemistry, meteorites and cosmochemistry, the carbon cycle and climate, trace elements, geochemistry of high and low temperature processes, and ore deposition, to name just a few. The geochemical behavior of the elements is described as is the state of the art in analytical geochemistry. Each topic incorporates cross-referencing to related articles, and also has its own reference list to lead the reader to the essential articles within the published literature. The entries are arranged alphabetically, for easy access, and the subject and citation indices are comprehensive and extensive. Geochemistry applies chemical techniques and approaches to understanding the Earth and how it works. It touches upon almost every aspect of earth science, ranging from applied topics such as the search for energy and mineral resources, environmental pollution, and climate change to more basic questions such as the Earth’s origin and composition, the origin and evolution of life, rock weathering and metamorphism, and the pattern of ocean and mantle circulation. Geochemistry allows us to assign absolute ages to events in Earth’s history, to trace the flow of ocean water both now and in the past, trace sediments into subduction zones and arc volcanoes, and trace petroleum to its source rock and ultimately the environment in which it formed. The earliest of evidence of life is chemical and isotopic traces, not fossils, preserved in rocks. Geochemistry has allowed us to unravel the history of the ice ages and thereby deduce their cause. Geochemistry allows us to determine the swings in Earth’s surface temperatures during the ice ages, determine the temperatures and pressures at which rocks have been metamorphosed, and the rates at which ancient magma chambers cooled and crystallized. The field has grown rapidly more sophisticated, in both analytical techniques that can determine elemental concentrations or isotope ratios with exquisite precision and in computational modeling on scales ranging from atomic to planetary.

This book was released on 2012-12-06 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book arises from a NATO-sponsored Advanced Study Institute on 'The Role of Air-Sea Exchange in Geochemical Cycling' held at Bombann@§. near Bordeaux, France. from 16 to 27 September 1985. The chapters of the book are the written versions of the lectures given at the Institute. The aim of the book is to give a comprehensive up-to-date coverage of the subject. presented in a teaching mode. The chapters contain much recent research material and attempt to give the reader an understanding of how the role of air-sea exchange in geochemical cycling can be quantitatively assessed. In the last decade, major advances in the fields of marine and atmospheric chemistry have underlined the role of physical, chemical and biological processes at and near the air-sea interface in a number of geochemical cycles (C. S, N, metals etc ... ). Further, there is strong concern over the anthropogenic perturbation of these cycles on both regional and global scales. The first part of the book (Chapters 1 to 8) provides a review of topics fundamental to such studies. These topics include concepts in geochemical modelling, assessment of atmospheric transport from sources to the oceans. description of mixing and transport processes within the ocean for both dissolved and particulate materials, quantification of air-sea fluxes for both gases and particles, photochemical transformations in the atmospheric and oceanic boundary layers.
