Modeling Post-Glacial Rebound Esther Adelstein• EPS 109 • Fall 2012 http://ancientshore.com/2009/07/30/on-the-level/
Initially Skip some math… y W0 z assume x http://upload.wikimedia.org/wikipedia/commons/f/fd/Glacier_weight_effects_LMB.png Skip more math… Integrate Turcotte and Schubert. Geodynamics. Second Ed. Cambridge University Press, 2002. Simulate rebound of a landscape with varying wavelengths • neglect forces in the z-direction • consequences of too small a wavelength relative to depression • reasonable results for large wavelengths -Hudson Bay, 5000km for depression of ~.5km, check with present-day rebound rate
