Volcanologist

“I study the chemistry of the gases that are emitted from volcanoes because it helps us to understand the ‘plumbing’ beneath them and forecast when they might erupt. It’s not always possible or sensible to collect samples directly from volcanoes, so I’ve been experimenting with long-range, high-altitude drones. Now we can fly them into a gas plume to collect measurements and samples, remotely and safely. My work takes me to amazing places. I was in Papua New Guinea four times last year. We discovered that the Manam volcano there releases huge amounts of carbon dioxide. It was a privilege to work with the local communities. They were as fascinated by us and our shiny gadgets, as we were by them and their beautiful culture. I also think we left a lasting impression because after we left, they set up their own Community Disaster Preparedness Committee to deal with future volcano hazards. It was wonderful to see and hear about that.”
