The Eyjabakkajokull glacial landsystem, Iceland: Geomorphic impact of multiple surges
A new glacial geomorphological map of the Eyjabakkajokull forefield in Iceland is presented. The map covers c. 60 km(2) and is based on high-resolution aerial photographs recorded in August 2008 as well as field checking. Landforms are manually registered in a geographical information system (ArcGIS...
