      Thomas, R.; Rignot, E.; Casassa, Gino; Rivera Ibáñez, Sergio; Kanagaratnam, P.; Acuña, César; Akins, T.; Brecher, Henry; Frederick, E.; Gogineni, P.; Krabill, W.; Manizade, S.; Ramamoorthy, H.; Russell, R.; Sonntag, J.; Swift, R.; Yungel, J.; Zwally, J. (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)
    • Elevation change and ice flow at Horseshoe Valley, Patriot Hills, West Antarctica 

      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 shrinkage and negative mass balance in the Chilean Lake District (40°S) 

      Rivera Ibáñez, Sergio; Bown, Francisca; Casassa, Gino; Acuña, César; Clavero, Jorge (Taylor & Francis, 2005)
      Ice-capped volcanoes of the Chilean Lake District have shown significant glacier retreat during recent decades, probably in response to tropospheric warming and precipitation decrease. Volcán Mocho-Choshuenco (39°55′S, ...
    • 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 and areal changes of glaciers from the Northern Patagonia Icefield, Chile 

      Rivera Ibáñez, Sergio; Benham, Toby; Casassa, Gino; Bamber, Jonathan; Dowdeswell, Julian A. (Elsevier, 2007)
      High thinning rates (up to −4.0±0.97 m a−1) have been measured at Campo de Hielo Patagónico Norte (CHN) or Northern Patagonia Icefield, Chile between 1975 and 2001. Results have been obtained by comparing a Digital Elevation ...
    • 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 ...
    • Variaciones recientes de glaciares en Chile 

      Casassa, Gino; Rivera Ibáñez, Sergio; Acuña, César (Universidad de Chile, 2000)
      Se presenta una síntesis de la investigación glaciológica realizada en Chile durante las últimas décadas, incluyendo los inventarios existentes, los balances de masa y las variaciones de glaciares, todo lo cual se analiza ...
    • Volume changes on Pio XI glacier, Patagonia: 1975-1995 

      Rivera Ibáñez, Sergio; Casassa, Gino (Elsevier, 1999)
      Pio XI glacier, with an area of 1263 km 2 and a length of 65.7 km, is the largest of the Southern Patagonia Icefield (SPD. During the period 1945-1995 it experienced a net advance of ca. 10 km., a unique behavior considering ...
