Graph of the Day: Ice-shelf Retreat in the Southern Antarctic Peninsula, 1947-2009

This image shows ice-front retreat in part of the southern Antarctic Peninsula from 1947 to 2009. USGS scientists are studying coastal and glacier change along the entire Antarctic coastline. The southern portion of the Antarctic Peninsula is one area studied as part of this project, and is summarized in the USGS report, Coastal-Change and Glaciological Map of the Palmer Land Area, Antarctica: 1947—2009 (map I—2600—C).
