Hello Reddit! My name is Tom Pering and I am currently a Teaching Associate at the University of Sheffield. My research focuses on the gases which volcanoes release. In particular, I am interested in volcanoes which have basaltic magmas. This type of magma allows the constant release of gases at the surface, which can then be measured using remote sensing techniques. As part of this, I am also interested in the modelling of how gas behaves within magmas, which then leads to a range of volcanic activities; such as strombolian eruptions. The research group in volcano remote sensing at the University of Sheffield has a strong history of developing such techniques. Recently we have developed a low-cost ultraviolet camera approach to remotely sense the volcanic gas sulphur dioxide (SO2), which incorporates the popular Raspberry Pi platform. Happy to answer questions about my research and more broadly about volcanology! Here are a few example papers from our recent research: Ultraviolet Imaging with Low Cost Smartphone Sensors: Development and Application of a Raspberry Pi-Based UV Camera - http://www.mdpi.com/1424-8220/16/10/1649 A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission measurements - http://www.mdpi.com/2072-4292/9/1/27 The dynamics of slug trains in volcanic conduits: evidence for expansion driven slug coalescence – http://www.sciencedirect.com/science/article/pii/S0377027316304267 Hello everyone! I am taking a break for a couple of hours but will keep an eye on this and return to answer questions at about 8 pm GMT (3 pm Eastern Time).
