(AMER ASSOC ADVANCEMENT SCIENCE, 2004-10-08)
      Recent aircraft and satellite laser altimeter surveys of the Amundsen Sea sector of West Antarctica show that local glaciers are discharging about 250 cubic kilometers of ice per year to the ocean, almost 60% more than is ...
    • Airborne laser altimetry survey of Glaciar Tyndall, Patagonia 
      Keller, Kristian; Casassa, Gino; Rivera Ibáñez, Sergio; Forsberg, Rene; Gundestrup, Niels (ELSEVIER SCIENCE BV, 2007-10)
      The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin ...
    • Current status of Andean glaciers 
      Casassa, Gino; Haeberlib, Wilfried; Jones, Gerry; Rivera Ibáñez, Sergio; Kaser, Georg; Ribstein, Pierre; Schneider, Christoph (ELSEVIER SCIENCE BV, 2007-10)

      Casassa, Gino; Rivera Ibáñez, Sergio; Acuña, César; Brecher, Henry; Lange, Heiner (INT GLACIOLOGICAL SOC, 2004)
      Patriot Hills is located at 80 degrees 18'S, 81 degrees 22'W, at the southernmost end of the Heritage Range, Ellsworth Mountains, West Antarctica. A comparison of glacier elevation data and ice velocities obtained by the ...
    • Glacier wastage on southern Adelaide Island, Antarctica, and its impact on snow runway operations 
      Casassa, Gino; Thomas, R.; Rignot, E.; Zamora, R.; Antúnez, D.; Acuña, César; Rivera Ibáñez, Sergio; Ordenes, F. (INT GLACIOLOGICAL SOC, 2005)
      The variations and dynamics of the southern edge of Fuchs Ice Piedmont, Adelaide island (67 degrees 45'09'S, 68 degrees 55'04'W), Antarctic Peninsula, are presented. The snow-covered surface of the glacier has been used ...
    • Ice-elevation changes of Glaciar Chico, southern Patagonia, using ASTER DEMs, aerial photographs and GPS data 
      Casassa, Gino; Bamber, Jonathan; Kaab, Andreas; Rivera Ibáñez, Sergio (INT GLACIOL SOC, 2005)
      Hielo Patagonico Sur (HPS; southern Patagonia icefield) is the largest temperate ice mass at mid-latitudes in the Southern Hemisphere. With few exceptions, the glaciers in this region have been retreating during the last ...
    • The surface energy balance of an active ice-covered volcano:Villarrica Volcano, Southern Chile 
      Brock, Benjamin; Casassa, Gino; Bown, Francisca; Rivera Ibáñez, Sergio; Acuña, César (International Glaciological Society, 2007-10)
      The energy balance of bare snow and tephra-covered ice near the glacier equilibrium line elevation on Villarrica Volcano, southern Chile, was investigated during 2004 and 2005, combining meteorological, surface temperature ...
