This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oxygen and carbon isotope composition (18O/16O and 13C/12C) of atmospheric carbon dioxide is an excellent tool to investigate the atmospheric CO2 cycle. In recent years, it has been suggested that the triple oxygen isotope composition (17O/16O and 18O/16O) of tropospheric CO2 might be a potential new tracer for the terrestrial gross primary production. This study investigates whether and to which extent this new tracer might complement conventional stable isotope investigations of tropospheric CO2. This thesis presents (i) a new high-precision technique for triple oxygen isotope analysi ...

Available in PDF, EPUB and Kindle. Book excerpt: Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the "missing sink" for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature.

Download or read book Carbon Dioxide Effects Research and Assessment Program Proceedings of the International Meeting on Stable Isotopes in Tree Ring Research New Paltz New York May 22 25 1979 written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Information about the past and present concentrations of CO/sub 2/ in the atmosphere and variations in climate can be obtained from measurements of stable isotopes in tree rings; specifically carbon-13, oxygen-18 and deuterium. The analysis of these stable isotopes in tree rings is a relatively new and rapidly developing field. This proceedings volume contains most of the papers presented at the meeting. The first paper gives an overview of the status of carbon-13 research. Papers relating to carbon-13 are in section I and grouped separately from the contributions on carbon-14. Although the meeting was primarily concerned with stable isotopes, all carbon isotopic analysis may be helpful in understanding the carbon-13 record in tree rings. The papers on hydrogen and oxygen isotope studies are in sections II and III respectively. The remaining sections contain papers that consider more than one isotope at a time, general topics related to isotopes, atmospheric changes and tree growth, and methods of isotopic analysis.

Download or read book Reconstruction of Northern Hemisphere Atmospheric Carbon Monoxide Mole Fraction and Stable Isotopes from Greenland Firn Air and Ice Cores written by Philip Fulton Place and published by . This book was released on 2021 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Carbon Monoxide (CO) is an important atmospheric trace gas that affects the oxidative capacity of the atmosphere by being a major sink of the hydroxyl radical. Ice cores may preserve a record of past atmospheric CO for analysis and interpretation; therefore, a new analytical system has been developed for analysis of CO mole fraction and stable isotopes ([delta]13CO and [delta]C18O) from ice core and atmospheric air samples. We present new measurements of past atmospheric CO and CO stable isotopes from firn air at Summit, Greenland, which provides a record from approximately 1965 to 2011 CE. A firn gas transport model and an inverse model were used to reconstruct atmospheric histories of CO mole fraction, [delta]13CO and [delta]C18O. The results show the highest values for CO mole fraction and isotopes in the early part of the record, with values declining from ~1980 to the present day. The negative trend in [delta]13CO and [delta]C18O intensified in the last decade. An isotope mass balance interpretation shows that the atmospheric CO decline was being driven by a decrease in emissions from fossil fuel combustion. Analyses of ice cores from Summit, Greenland using continuous flow analysis (CFA) revealed large and rapid variations in CO mole fraction with depth. We conducted experiments using gas-free ice core samples from different locations to investigate the possibility that some of the observed elevation in CO mole fraction was due to CO production from organics in the ice during melting. The results show that melt-extraction in our system does not result in CO production from trace organics in the ice and, by extension, that the elevated and highly variable CO values observed are likely due to in situ CO production in the ice itself. Baseline records of CO mole fraction are recovered from the CFA data and show relatively steady CO values from 1700 to 1850, with CO mole fraction rapidly increasing into the 1960s. Due to the in situ production, it is unlikely that atmospheric histories of CO stable isotopes will be recoverable from Greenland ice until the in situ CO production mechanism is better understood"--Pages ix-x.

Available in PDF, EPUB and Kindle. Book excerpt: The warming of the Earth has been the subject of intense debate and concern for many scientists, policy-makers, and citizens for at least the past decade. Climate Change Science: An Analysis of Some Key Questions, a new report by a committee of the National Research Council, characterizes the global warming trend over the last 100 years, and examines what may be in store for the 21st century and the extent to which warming may be attributable to human activity.
Download or read book Stable Isotopes in Ecology and Environmental Science written by Robert Michener and published by John Wiley & Sons. 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.
