Rivera, A., Casassa, G., Acuña, C. & Lange, H. (2000) : "Variaciones recientes de glaciares en chile" Revista Investigaciones geográficas, 34: 25-52.

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 con relación a los cambios climáticos que han afectado el país. En Chile s...

This paper is a contribution to the understanding of the topoclimatic and environmental geography of the basin where Santiago — one of the most polluted Latin American city — is located. In the first part, land-use change is analysed looking at the climatic transformation caused by the rapid...


Aniya, M., Naruse, R., Casassa, G., & Rivera, A. (1999) : "Variations of Patagonian glaciers, South America, utilizing RADARSAT images" Proceedings of the International Symposium on RADARSAT Application Development and Research Opportunity (ADRO), Montreal, Canada, October 13-15, 1998, CD-ROM.

Combining RADARSAT images (1997) with either Landsat MSS (1987 for NPI) or TM (1986 for SPI), variations of major glaciers of the Northern Patagonia Icefield (NPI, 4200 km2) and of the Southern Patagonia Icefield (SPI, 13,000 km2) were studied. Of the five NPI glaciers studied, San Rafael Glacier...


Rivera,A., & Casassa,G. (1999) : "Volume Changes on Glaciar Pio XI, Patagonia: 1975-1995" Global and Planetary Change , 22(1-4):233-244.

Pio XI glacier, with an area of 1263 km² and a length of 65.7 km, is the largest of the Southern Patagonia Icefield (SPI). During the period 1945–1995 it experienced a net advance of ca. 10 km., a unique behavior considering that virtually all neighboring glaciers are retreating. Two maps...


Romero, H and Rivera, A. (1998) : "Antecedentes Paleoambientales para el desarrollo sustentable de la Región de Antofagasta, Chile" Bamberger Geographische Schriften, 15: 335-349.

The region of Antofagasta, located in the northernmost section of Chile is one of those apparently stable landscapes as a consequence of its desertic nature. However, its long term climatic variability has allowed the origin and evolution of several resources, like water, soils and vegetation, wh...


Casassa, C., Brecher, H., Cárdenas, C. & Rivera, A. (1998) : "Mass balance of the Antarctic ice Sheet at patriot Hills" Annals of Glaciology, 27: 130-134.

Glaciological data collected at Patriot Hills, Antarctica (80°18'S, 81°22'W), are used to assess the local mass balance of the ice sheet. The data were collected during two field campaigns conducted by the Instituto Antártico Chileno in January and November 1995. Measurements included surveying o...
