Sampling on Kilauea Volcano, Hawai'i.
Dr Marie Edmonds studies the physics and chemistry of volcanic eruptions. Volcanoes are vents for gases and lavas, whose chemistry allows us to infer the structure and composition of the Earth's interior. Explosive volcanic eruptions pose a significant hazard to populations living nearby and therefore it is crucial to understand how they are triggered and sustained.

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.
