Erosion by summertime melt-driven streams on Greenland’s ice sheet shapes landscapes similarly to, but much faster, than do rivers on land, according to a new study. The approach used to study the drainage system of the ice sheet should serve to broaden the scientific understanding of melt rates and improve projections about ice sheet response to climate change, said Leif Karlstrom, a geologist at the University of Oregon in Eugene and lead author of the study.
