For GSS Climate Change chapter 8.  Excerpt: Scientists at NASA and the University of California, Irvine (UCI), have found that canyons under Greenland's ocean-feeding glaciers are deeper and longer than previously thought, increasing the amount of Greenland's estimated contribution to future sea level rise. ...The results were published Sunday in the journal Nature Geoscience.  ...An animation of the newly mapped bed topography is available at: http://youtu.be/g_6a7SloMsY.... http://www.nasa.gov/press/2014/may/hidden-greenland-canyons-mean-more-sea-level-rise/#.U3rZgy9GLhw - NASA RELEASE 14-141.
