Dr. Hallberg has been actively involved in three ocean Climate Process Teams, studying Gravity Current Entrainment, Eddy-Mixed Layer Interactions, and Internal Wave Driven Mixing. These teams aim to improve the representation of these processes in climate-scale models, based on the best understanding that can be obtained from observations, process studies, and theory. He is currently working on coupling a dynamic ice-sheet and ice-shelf model with high resolution versions of GFDL?s coupled climate models for improved prediction of sea-level rise, and is leading the effort to modernize GFDL's sea-ice model.
