    • Climate changes and recent glacier behaviour in the Chilean Lake District 

      Bown, Francisca; Rivera Ibáñez, Sergio (ELSEVIER SCIENCE BV, 2007-10)
      Atmospheric temperatures measured at the Chilean Lake District (38°–42°S) showed contrasting trends during the second half of the 20th century. The surface cooling detected at several meteorological stations ranged from ...
    • Glacier responses to recent volcanic activity in Southern Chile 

      Bown, Francisca; Carrión, Daniela; Zenteno, Pablo; Rivera Ibáñez, Sergio (IOP PUBLISHING, 2012)
      Glaciers in Southern Chile (39–43 S) are characterized by frontal retreats and area losses in response to the ongoing climatic changes at a timescale of decades. Superimposed on these longer-term trends, volcanic activity ...
    • 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, ...
    • I ghiacciai del Cile come indicatori dei cambiamenti climatici - Chilean Glaciers as indicators of climate change 

      Bown, Francisca; Acuña, César; Rivera Ibáñez, Sergio; Ordenes, Fernando (CONSEJO NACIONAL DE INVESTIGACIONES CIENTIFICAS Y TECNICAS, 2008)
      This work presents a summary of Chile’s present glacial environment and its most significant recent variations. Though the behaviour of some glaciers may be driven by non-climatic factors, the majority of them experienced ...
    • Recent glacier variations at the Aconcagua basin, central Chilean Andes 

      Bown, Francisca; Rivera Ibáñez, Sergio; Acuña, César (International Glaciological Society, 2008-06)
      The majority of glaciers in central Chile have receded in recent decades, from >50m to only a few meters per year, mainly in response to an increase in the 08C isotherm altitude. The Aconcagua river basin (338 S) is one ...
    • Recent glacier variations on active ice capped volcanoes in the Southern Volcanic Zone (37 

      Rivera Ibáñez, Sergio; Bown, Francisca (Elsevier, 2013)
      Glaciers in the southern province of the Southern Volcanic Zone (SVZ) of Chile (37e46 S) have experienced significant frontal retreats and area losses in recent decades which have been primarily triggered by tropospheric ...
    • 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 ...
