PPT-A distributed glacier model for RASM

Jeremy Fyke Bill Lipscomb Los Alamos National Laboratory Goal Simulate the coupled evolution of Arctic glaciers and ice caps within RASM Evolving land ice area A ffects vegetation extent and albedo. deGeer. Moraines . Erica . Doody. What is a . deGeer. moraine?. Small moraine ridges that occur in clusters parallel to each other. Usually found in coastal marine settings. First identified by Gerard . What are the processes of glacial erosion?. They erode by two main processes. As a glacier moves down a valley, it creates pressure on the land which creates heat. This melts part of the glacier. This water runs into small cracks, it the refreezes as it gets colder (freeze-thaw). modelling. Jeremy . Fyke. (LANL). Bill Lipscomb (LANL). Bill Sacks (NCAR). Valentina. . Radic. (UBC, Canada).
