Covid-19 update

Dear all

(Update 21 aug 2020)

Based on the latest information on international travel and the restrictions imposed on arrivals to Norway we do not think it is possible to arrange the 25th International Symposium on Ice in Trondheim as a physical meeting. We have therefore decided that we will arrange the symposium as a virtual conference from the 23rd to the 25th of November. We intend to publish the proceedings from the conference as usual. We will get back to you as soon as possible with information about the virtual meeting and how to register for the conference.

Best Regards,
The 25th IAHR Ice Symposium organising committee

25th IAHR International Symposium on Ice

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.
