Resumen / Abstract.

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 showed a net advance, while other glaciers, San Quintin, Steffen, Colonia and Nef retreated during the same period. With additional data of JERS-1 images (1994), different patterns of variations for periods of 1986-94 and 1994-97 are recognized. Of the seven SPI glaciers studied, Pio XI Glacier, the largest in South America, showed a net advance, gaining a total area of 5.66 km2.
