Gases from volcanoes are an important regulator of atmospheric composition, and large eruptions can affect global climate. The amount of gases contained in magma (molten rock) and the way in which bubbles form and rise through it are important controls on the style of volcanic eruptions. In this photo, Marie is using an infrared spectrometer to measure the composition of volcanic gases at Kilauea Volcano, Hawai'i.
Marie teaches igneous petrology, geochemistry and volcanology. She is a Fellow of Queens' College.
