Bown, F. (2004) : "Cambios climáticos en la Región de Los Lagos y respuestas recientes del Glaciar Casa Pangue (41º08'S)" Memoria de Magister en Geografía, Universidad de Chile, Santiago, 131 pp.

Las temperaturas atmosféricas en la Región de Los Lagos (39° - 42°S) presentaron tendencias divergentes durante la segunda mitad del siglo XX, al obtenerse temperaturas medias superficiales de las estaciones meteorológicas que mostraron tasas de enfriamiento entre –0.014ºC a-1 y –0.021ºC a-1, mie...


Thomas, R., Rignot, E., Casassa, G., Kanagaratnam, P., Acuña, C., Akins, T., Brecher, H., Frederick, E., Gogineni, P., Krabill, W., Manizade, S., Ramamoorthy, H., Rivera, A., Russell, R., Sonntag, J., Swift, R. and J. Yungel (2004) : "Accelerated sea level rise from West Antarctica" Science, 306, 255-258.

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 accumulated within their catchment basins. This discharge is sufficient to ...


Rignot E., Casassa, G. Gogineni, P. Krabill, W. Rivera, A. and Thomas R. (2004) : "Accelerated ice discharge from the Antarctic Peninsula following the collapse of Larsen B ice shelf" Geophys. Res. Lett, 31, L18401, doi:10.1029/2004GL020697.

Interferometric synthetic-aperture radar data collected by ERS-1/2 and Radarsat-1 satellites show that Antarctic Peninsula glaciers sped up significantly following the collapse of Larsen B ice shelf in 2002. Hektoria, Green and Evans glaciers accelerated eightfold between 2000 and 2003 and decele...


Rignot, E., R. Thomas, P. Kanagaratnam, G. Casassa, E. Frederick, S. Gogineni, W. Krabill, A. Rivera, R. Russell, J. Sonntag, R. Swift and J. Yungel (2004) : "Improved estimation of the mass balance of the glaciers draining into the Amundsen Sea sector of West Antarctica from the NASA/CECS 2002 campaign" Annals of Glaciology, 39, 231 - 237.

In November–December 2002, a joint airborne experiment by Centro de Estudios Científicos and NASA flew over the Antarctic ice sheet to collect laser altimetry and radio-echo sounding data over glaciers flowing into the Amundsen Sea. A P-3 aircraft on loan from the Chilean Navy made four flights o...


Casassa, G., A. Rivera, C. Acuña, H. Brecher and H. Lange (2004) : "Elevation change and ice flow at Horseshoe Valley, Patriot Hills, Antarctica" Annals of Glaciology, 39, 20 - 28.

Patriot Hills is located at 80º18' S, 81º22'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 differential global positioning system in the period 1996–97 is presented. Ablation/ accumu...


Rivera, A. and G. Casassa (2004) : "Ice elevation, areal, and frontal changes of glaciers from National Park Torres del Paine, Southern Patagonia Icefiled" Artic, Antarctic and Alpine Research, 36(4), 379 - 389.

Ice elevation changes since 1975 and ice areal changes since 1945 of glaciers in the southeastern part of the Southern Patagonia Icefield (SPI) are presented. Comparison of digital elevation models, GPS, and optical survey data revealed high thinning rates for all the ablation areas of the glacie...
