Exercise 2. Deglaciation Experiment
In this exercise you will work with a UMISM “deglaciation” experiment. The model has been fine-tuned so that the ice sheet disappearance matches known glacial geology better than in the previous experiment. There are two broad animation views: hemispheric and local. First examine the North American animations, then zoom in on Maine. (See README.txt in the Experiment 2 folder for file descriptions). Guiding questions:
- Characterize the glacial termination. How does this one differ from the termination sequence you saw in the previous exercise?
- Approximately how far below the present surface is Hudson Bay depressed at time -17,400? In general terms, what do you think might be happening here?
- Why doesn’t the Greenland Ice Sheet disappear?
- How far inland does the model predict that seawater intruded? Was there ever ocean-front property in Orono?
