(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 ...
-
(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 ...
-
(Universidad de Chile, 2010)En este trabajo se estudian las variaciones de cinco glaciares localizados en Campo de Hielo Sur (Occidental, Greve, HPS8, Lautaro y Pío XI) y el comportamiento del lago Greve, así como las tendencias climáticas pronosticadas ...
-
(Copernicus Gesellschaft MBH, 2017)Glacier melt is an important source of water for high Andean rivers in central Chile, especially in dry years, when it can be an important contributor to flows during late summer and autumn. However, few studies have ...
-
(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 ...

-
(Cambridge University Press, 2016)In contrast to the general trend for glaciers of the Southern Patagonia Icefield, Glaciar Pio XI has experienced a large cumulative frontal advance since 1945. In an effort to better understand this advancing behaviour, ...

-
(Natl Acad Sciences, 2020)The future response of the Antarctic ice sheet to rising temperatures remains highly uncertain. A useful period for assessing the sensitivity of Antarctica to warming is the Last Interglacial (LIG) (129 to 116 ky), which ...
-
(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 ...
-
(Universidad de Chile, 2014)Se presentan los resultados obtenidos en estudios llevados a cabo en los glaciares de los Nevados de Chillán (37ºS) donde se buscó caracterizar el comportamiento glaciar en respuesta al cambio climático y a los posibles ...
-
(ELSEVIER SCIENCE BV, 2005-11-01)Elucidating the timing and extent of former glacier fluctuations is important because of the palaeoclimatic inferences that can be drawn from such studies. Here we present new geomorphological evidence of the patterns of ...
-
(Elsevier, 2009)This paper presents an updated, extensive review of glacier fluctuations during the past 1000 years in the extratropical Andes of South America between ca. 17° and 55°S. Given the variety of environmental conditions and ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(International Glaciological Society, 2008-12)Volc´an Villarrica (39◦25 12 S, 71◦56 27 W; 2847ma.s.l.) is an active ice-capped volcano located in the Chilean lake district. The surface energy balance and glacier frontal variations have been monitored for ...
