Professor Danny Feltham receives the IGS Seligman Crystal award
11th May 2026
We are delighted to announce that Professor Daniel Feltham (University of Reading), CPOM Principal Investigator: Sea Ice Modelling, has been awarded the Seligman Crystal by the International Glaciological Society (IGS).
The Seligman Crystal is awarded to a single person or a collaborative group/team that has made exceptional scientific contributions to glaciology, defined as any snow and/or ice studies.
The award recognises Professor Feltham’s pioneering contributions to sea ice physics, from the mechanics of how ice breaks, drifts, and melts, to the fluid dynamics of melt ponds and their role in accelerating ice loss. His work enhancing the development of the CICE model (the world’s most widely used sea ice model) has ensured the most recent physical discoveries have been incorporated into the code used by the IPCC and national weather services.
Petra Heil, the Chair of the IGS Awards Committee, stated in the citation.
“Professor Feltham’s extensive body of work and his dedication to scientific excellence have made him a towering figure in cryospheric physics. His innovation in applying mathematical rigour to the complex, multi-scale problems of sea ice has transformed how we understand and predict the future of the polar regions.“
