Richard Peltier was chosen for his seminal cross-disciplinary research into the physics of the Earth: combining studies of the ocean, the interior of the Earth, and the atmosphere to highlight the interconnections that lead to global climate change.

Despite chemical knowledge about CO 2 that extends back centuries, some data bases are still evolving that are needed to predict even the sub-critical CO 2 behavior down the geothermal gradient's P - and T -values which will be encountered in sequest

Temperature-resolved analyses of volatiles from Mid-Ocean-Ridge-Basalt (MORB) and vitreous basaltic rims were carried out to investigate the total volatile contents of basaltic melts and the influence of magma contamination on the degassing behaviour

Electrochemical cells are reviewed and a new design is evaluated for potentiometric pH measurements to above 300 jC. The new design system minimizes the effects of metal corrosion on measured pH. In addition, a recently developed [Zhou, X.Y., Lvov, S

Samples of Mexican obsidian that exhibit either “sheen” or “rainbow” optical properties were examined with a combination of EMP, SEM, TEM, as well as visible and IR spectroscopy. Electron-microprobe analyses of the sheen matrix give (in wt.%)

ZrO2-EMF measurements were carried out on natural biotite samples between about 400 and 1100 8C in a closed system in a pure argon atmosphere (99.9999%). The EMF patterns are complex and cannot be compared to classical equilibrium 1/T-log ƒ data. In

ZrO2 oxygen sensors, gas mixtures, and conventional solid buffers have been used for decades to either control or measure oxygen fugacity (ƒ O2) at high temperatures. In dry systems below ca. 700°C these techniques were used cautiously, if at all,
