ROGUE: Dynamics of the Greenland Ice Sheet
Project (finished)
Realtime Observations of the Greenland Under-ice Environment (ROGUE)
The ROGUE project is an international multi-insitute collaboration to understand the dynamical processes at the base of the Greenland Ice Sheet. Basal processes influencing spring speedup and summer slowdown are barely understood, yet are crucial for the dynamics of the ice sheet.
