Occasional YouTube video #1 - Modelling glacial erosion


David Egholm has posted a video of the numerical model of glacial erosion described in Nature (Egholm et al., 2009), illustrating what would happen if the Spanish Sierra Nevada (largely unglaciated during the Quaternary) were subjected to dramatic climate cooling and subsequent substantial glacial erosion. This is definitely a major development compared with previous glacial landscape evolution models, so watch out for more from David and his PhD student Vivi Pedersen as they continue their research into glacial erosion using their new model (more details about the model are available from JGR-ES here), and new topographic analyses.
