Professor of Glaciology, Arctic Five Chair, University of Tromsø

Alun is an applied glaciologist interested in subglacial processes, cryosphere / methane-hydrate interactions and the dynamic response of glaciers and ice sheets to atmospheric, oceanic and geological forcing. He holds an Arctic Five research chair to address the long-term stability and legacy of the cryosphere and its impact on the environment, landscape, carbon-cycle, and broader impacts on sea-level rise and society. His approach applies novel field-data to improve process understanding and constrain models with ongoing projects across the Arctic, focusing on Greenland, Alaska and the Barents Sea with additional interests in Patagonia, Alaska, Asia and Antarctica. He has led over 60 successful research/exploration expeditions across all icy regions of the planet, many conducted self-sufficiently from his own sailboat and using a heli-logistics non-profit he set up. He is a popular commentator on the environment, and presented in and supported many gong-winning documentaries including Frozen Planet (1 & 2), Our Planet, Operation Iceberg, Into the Ice and Chasing Ice etc.
