Measurements of noble gas in the atmosphere are a powerful tool to study natural and anthropogenic changes in the Earth system. The chemically inert nature of noble gases means that they are only impacted by physical processes, greatly simplifying the interpretation of observations. Furthermore, fast atmospheric mixing intrinsically integrates global signals on time scales beyond one year allowing local records to capture global changes. Air samples can be obtained in a variety of ways including directly from the atmosphere, from reservoirs intentionally archived by humans, or from small bubbles trapped naturally in ancient ice, enabling the reconstruction of atmospheric changes over a wide range of timescales. However, atmospheric noble gas measurements are challenging because the signals we chase are often small, and analytical methods are still being developed and improved upon. In four chapters, this dissertation aims to deepen our understanding of noble gases as geochemical tracers and highlights new methods and applications of noble gas analyses. Chapter 1 explores the processes that cause small offsets between atmospheric air and air preserved in ice using a 2-D numerical model of air transport through snow. Chapter 2 demonstrates a connection between atmospheric circulation in the upper atmosphere and the in-situ argon-to-nitrogen (Ar/N2) ratio using samples collected by aircraft. Chapter 3 introduces a novel mass spectrometric technique for the precise measurement of small changes in the atmospheric helium abundance and outlines potential scientific applications. Finally, Chapter 4 builds on Chapter 3 and presents the first record of an atmospheric helium build-up which can be linked directly to anthropogenic fossil fuel activity.

The twelve chapters of this volume aim to provide a complete manual for using noble gases in terrestrial geochemistry, covering applications which range from high temperature processes deep in the Earth’s interior to tracing climatic variations using noble gases trapped in ice cores, groundwaters and modern sediments. Other chapters cover noble gases in crustal (aqueous, CO2 and hydrocarbon) fluids and laboratory techniques for determining noble gas solubilities and diffusivities under geologically relevant conditions. Each chapter deals with the fundamentals of the analysis and interpretation of the data, detailing sampling and sampling strategies, techniques for analysis, sources of error and their estimation, including data treatment and data interpretation using recent case studies.

After the discovery that elements were commonly composed of isotopes, there developed a range of studies of the variability of isotopic compositions in Earth materials, which was able to add to our understanding of Earth processes and history. This collection of chapters from the Treatise on Geochemistry describes the range of isotopic studies. The chapters are grouped into the following categories: light stable isotopes, radiogenic tracers, noble gases and radioactive tracers. The first three groups depend on mass spectrometric measurements. The section on radioactive tracers employs both radioactive counting techniques and the newly developed accelerator mass spectrometric techniques. Comprehensive, interdisciplinary and authoritative content selected by leading subject experts Robust illustrations, figures and tables Affordably priced sampling of content from the full Treatise on Geochemistry

Though largely inaccessible, the geochemistry of Earth's mantle and core can be examined through a wide variety of approaches. Volume 2 focuses first on "remote" sensing using evidence from cosmochemical, seismic, petrologic and geochemical approaches. Mantle composition is then examined in detail through descriptions of mantle samples brought to Earth's surface through tectonic, volcanic, and volatile-outgassing processes. The volume concludes with examination of processes that modify the composition of the mantle and core including an early magma ocean, partial melting, element partitioning between minerals and melts, and physical mixing caused by plate subduction, mantle convection and mass exchange between mantle and core.

Volume 77 of Reviews in Mineralogy and Geochemistry focuses on important aspects of the geochemistry of geological CO2 sequestration. It is in large part an outgrowth of research conducted by members of the U.S. Department of Energy funded Energy Frontier Research Center (EFRC) known as the Center for Nanoscale Control of Geologic CO2 (NCGC). Eight out of the 15 chapters have been led by team members from the NCGC representing six of the eight partner institutions making up this center - Lawrence Berkeley National Laboratory (lead institution, D. DePaolo - PI), Oak Ridge National Laboratory, The Ohio State University, the University of California Davis, Pacific Northwest National Laboratory, and Washington University, St. Louis.
