    • 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 ...
    • 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 ...
    • 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 ...
