Research by the U.S. Geological Survey is the first to document that every ice front in the southern part of the Antarctic Peninsula has been retreating overall from 1947 to 2009, with the most dramatic changes occurring since 1990. The USGS previously documented that the majority of ice fronts on the entire Peninsula have also retreated during the late 20th century and into the early 21st century. The report, “Coastal-Change and Glaciological Map of the Palmer Land Area, Antarctica: 1947—2009” and its accompanying map is available online.
