Covid-19 update

Dear all

The conference is scheduled for the 23 - 26th of November. We do hope we can arrange a meeting in Trondheim, but in the case travel restrictions makes this impossible we intend to arrange the conference as a virtual meeting. We will decide on this in August when we have more information on restrictions on meetings and travel for the fall.

Best Regards,
The 25th IAHR Ice Symposium organising committee

The 25th IAHR International Symposium on Ice

Welcome to Trondheim, Norway in November 2020! The Norwegian University of Science and Technology (NTNU) will host the 25th IAHR International Symposium on Ice.

The registration is temporarily closed, as we re-schedule for November 2020.

Changes to the cold climate regions of the world creates challenges related to the state of ice in both fresh and sea water. These challenges relate to fundamental ice processes, engineering aspects of ice and environmental issues in all areas were ice forms. The IAHR ice symposium is focused on presenting and discussing topics related to ice in both fresh and sea water and should provide a venue for addressing current topics in ice engineering and research.

We do invite you all to the Norwegian University of Science and Technology in June of 2020 for the 25th IAHR Symposium of Ice, 26 years after the first time the symposium was arranged in Trondheim. The conference will start with an ice breaker on Sunday the 14th of June and end with lunch on Thursday the 18th of June. We look forward to seeing you in Trondheim in 2020.
