This 1 minute movie shows the evolution of ice and topography during the last 120 thousand year glacial cycle, as computed by the MUN/UofT glacial systems model. Pay attention to the speed of the changing ice extent and to the changing shoreline (which in this movie is simply based on an eustatic approximation). Ice sheets are dynamic!
The MUN/UofT 3D thermo-mechanically coupled model includes till deformation, visco-elastic bedrock deformation, surface meltwater drainage, and physically based parameterizations for surface mass-balance and ice calving. Ice margins are constrained to fit the chronology of Dyke et al (2003). The model is calibrated for the last deglacial interval, but so far lacks significant constraints prior to last glacial maximum. (Thanks to Guido Vettoretti for the graphical projection.)
