Fig. 1. Continental and regional maps illustrating the geographic context of the southern McMurdo Ice Shelf overlaid by the 2014–2015 UTIG airborne survey tracks (red lines). This study addresses the portion of the tracks covering SMIS and RIS. The background is the Landsat image mosaic of Antarctica (Bindschadler and others, 2008). All the maps in this paper use a standard universal polar stereographic (UPS) projection with a metric-based Cartesian ‘easting/northing’ coordinate system.
