Ice flow modelling group

The ice flow modelling group at Centre for Ice and Climate studies ice sheets and glaciers in the climate system. Our research interests cover glaciological themes related to ice flow modelling and observations, surface mass balance and evolution of ice sheets. 

Weekly group meetings.

Virtual meetings every Thursdays at 9.00-10 organized by Christine Hvidberg. Sign up to the maillinglist here:
