A spatial and temporal study of the carbon cycle; the role of carbonates in buffering Earth’s climate
… have been attributed to an imbalance between volcanic degassing rates and silicate weathering. To force environmental changes in this way, such as the CO<sub>2</sub> decline observed during the Cenozoic Period (66 Myr - present), requires either a decrease in volcanic degassing, or an increase …

The Atmospheric Fingerprints of Volcanism: Simulating Volcanic Outgassing and Secondary Atmospheres on Rocky Planets
… its atmosphere, with the aim of analysing how a volcanically derived or supplemented atmosphere may appear, both under the end-member case where volcanism is the only factor affecting the atmosphere, and when changing surface temperatures and atmospheric escape is considered. Chapter 2 describes …

Infrared spectroscopy of volcanic gases at Masaya, Nicaragua
Volcanic gases carry valuable information about processes occurring at active volcanoes, and so their accurate measurement and analysis are highly desirable. Masaya is a low-lying persistently active basaltic volcano, which is renowned for strong passive gas emission unaccompanied by lava …

Magmatic and volcanic processing of volatile and chalcophile elements
… also partition into exsolving magmatic fluids. Degassing and sulfide saturation occur ubiquitously during magma evolution, yet the impact that these processes exert on the abundance and distribution of copper in magmatic systems, and more specifically in exsolving magmatic fluids, remain …
