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: https://mailman.nbi.ku.dk/mailman/listinfo/cic_modelling.

Annual Greenland Ice Sheet Seminar
Network meeting between research groups in Denmark working on the Greenland Ice Sheet held the first Thursday in January. Contact Christine Hvidberg for further information (Email below).
Next meeting: January 7, 2021 at DTU. OBS Cancelled this year due to COVID-19, substitute network activities will be announced
