• Volcanic Crystal Clocks and CO2: Transforming our Prospects for Predicting Huge Eruptions

Talks organised by John Maclennan

This list is based on what was entered into the 'organiser' field in a talk. It may not mean that John Maclennan actually organised the talk, they may have been responsible only for entering the talk into the talks.cam system.
