Abstract 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 0˚C isotherm altitude. The Aconcagua river basin (33˚ S) is one of the major glaciated basins in central Chile, with 121 km2 of ice in 2003. An earlier inventory using 1955 aerial photographs yielded a total surface area of 151 km2, implying a reduction in glacier area of 20% (0.63km2 a–1) over the 48 years. Photographic stereo… 
Sudden glacier advances in the Cachapoal Valley, Southern Central Andes of Chile (34°S)
Abstract Throughout the Andes Mountains of South America, a general trend of glacier shrinkage has taken place in modern times. However, a few glaciers have undergone considerable temporally advances
Glacier inventory of the upper Huasco valley, Norte Chico, Chile: glacier characteristics, glacier change and comparison with central Chile
Abstract Results of a new glacier inventory of the upper Huasco valley, which lies within the arid Norte Chico zone of the Chilean Andes, are presented for 2004. Despite the high altitude, the
Glacier area changes in the central Chilean and Argentinean Andes 1955–2013/14
ABSTRACT To improve our knowledge of glacier area changes in the central Chilean and Argentinean Andes (32°9′S–33°4′S), two new glacier inventories from 1989 to 2013/14 are compared with a
Glacier inventory and recent glacier variations in the Andes of Chile, South America
ABSTRACT The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is
Glacier fluctuations in extratropical South America during the past 1000 years
article i nfo 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
Glacier decline in the Central Andes (33°S): Context and magnitude from satellite and historical data
Abstract Central Andes (33°S) represent a water-scarce region. During arid years, glacier runoff may constitute the main hydrological input at warm season and hence a steadfast deglacierization may
60 Years of Glacier Elevation and Mass Changes in the Maipo River Basin, Central Andes of Chile
The first long-term (1955–2013/2015), region-specific glacier elevation and mass change estimates for the Maipo River Basin, from which the densely populated metropolitan region of Chile obtains most of its freshwater supply are presented.
New evidence of glacier surges in the Central Andes of Argentina and Chile
In contrast to the large surge-type glacier clusters widely known for several mountain ranges around the world, the presence of surging glaciers in the Andes has been historically seen as marginal.
Glacial lakes of the Central and Patagonian Andes
Abstract The prevalence and increased frequency of high-magnitude Glacial Lake Outburst Floods (GLOFs) in the Chilean and Argentinean Andes suggests this region will be prone to similar events in the
Glacier Inventory: A Case in Semiarid Chile
Glaciers are the most important water reservoirs found in the Andes. While the scientific community has conducted more extensive glaciological studies in southern Chile, it is only recently that


On the Future of the Water Resources from Glacier Melting in the Cordillera Blanca, Peru
The hydrological data (since 1953) of the Llanganuco basin show an increase of the glacial melting during the last quarter of the 20th century, and the forcing of the model by forecasts of the future temperature evolution above the Cordillera Blanca, derived from the regionalization of global climatic models allows improvement of the estimations only based on past glacial behaviour.
Ice elevation and areal changes of glaciers from the Northern Patagonia Icefield, Chile
Abstract High thinning rates (up to − 4.0 ± 0.97 m a − 1 ) have been measured at Campo de Hielo Patagonico Norte (CHN) or Northern Patagonia Icefield, Chile between 1975 and 2001. Results have been
Glacier change and climate forcing in recent decades at Gran Campo Nevado, southernmost Patagonia
Abstract Digital terrain models of the southern Chilean ice cap Gran Campo Nevado reflecting the terrain situations of the years 1984 and 2000 were compared in order to obtain the volumetric glacier
Glacier inventory of the Gran Campo Nevado Ice Cap in the Southern Andes and glacier changes observed during recent decades
Abstract The Gran Campo Nevado (GCN) forms an isolated ice cap on the Peninsula Munoz Gamero (PMG) located 200 km to the south of the Southern Patagonia Icefield (SPI). We present a glacier inventory
Use of remotely sensed and field data to estimate the contribution of Chilean glaciers to eustatic sea-level rise
Abstract A synthesis of glaciological studies carried out in Chile during recent decades is presented, including inventories and records of glacier variations, fluctuations of which are related to
A first shallow firn-core record from Glaciar La Ollada, Cerro Mercedario, central Argentine Andes
Abstract In January 2003, shallow firn cores were recovered from Glaciar Esmeralda on Cerro del Plomo (33°14’S, 70°13’W; 5300 ma.s.l.), central Chile, and from Glaciar La Ollada on Cerro Mercedario
