Polar ice science wins prize crystal for pioneer professor
12 May 2026
Professor Danny Feltham has been awarded the Seligman Crystal by the International Glaciological Society, one of the highest international honours in glaciology.
The Seligman Crystal is the Society's senior scientific award, presented for outstanding and sustained scientific contribution to the understanding of snow and ice on Earth.
Named after Gerald Seligman, a founder of the IGS, the prize has been awarded only selectively since its creation, marking it as a rare and highly prestigious distinction within the global cryospheric science community.
Professor Feltham said: "I am incredibly grateful to the International Glaciological Society for this award, and to my wonderful scientific colleagues. Almost all high-quality research comes as a result of talented people working effectively as a team, and I have benefited from the great privilege of having worked with some of the best ice scientists in the world throughout my career."
'Scientifically exceptional'
Professor Feltham, who works in the University of Reading's Department of Meteorology, is internationally recognised for his pioneering research into sea ice thermodynamics, dynamics and ice-ocean interactions.
His work has played a crucial role in advancing scientific understanding of how polar ice responds to a warming climate, with significant implications for ocean currents, weather patterns and global climate systems.
The IGS Awards Committee described Professor Feltham’s contribution as scientifically exceptional and influential across the field of glaciology.
The award underscores the continued world‑class research excellence at the University of Reading in climate and environmental science. Reading is internationally respected for its research strength in weather, climate and environmental processes, and Professor Feltham’s recognition reinforces the University’s reputation as a global leader in research.
The Seligman Crystal will be formally conferred at an upcoming International Glaciological Society meeting.
