A comparison of ice drift motion from modeled and buoy data
U.S. Naval operations in the Arctic require an effective way to predict the movement and behavior of sea ice. This is currently provided by the Navy's PIPS model which is based on Hibler's (1979) sea ice model which combines the thermodynamic ice heat budget with a dynamic ice model sensit...
