Rivera, A. and F. Bown (2013) : "Recent glacier variations on active ice capped volcanoes in the Southern Volcanic Zone (37º-46ºS), Chilean Andes" Journal of South American Earth Sciences, 45: 345-356.

Glaciers in the southern province of the Southern Volcanic Zone (SVZ) of Chile (37-46ºS) have experienced significant frontal retreats and area losses in recent decades which have been primarily triggered by tropospheric warming and precipitation decrease. The resulting altitudinal increase of ...


Fretwell P. and 59 others including A. Rivera (2013) : "Bedmap2: improved ice bed, surface and thickness datasets for Antarctica" The Cryosphere, 7: 375-393.

We present Bedmap2, a new suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60ºS. We derived these products using data from a variety of sources, including many substantial surveys completed since the ori...


Falaschi, D. C. Bravo , M. Masiokas, R. Villalba and A. Rivera (2013) : "First Glacier Inventory and Recent Changes in Glacier Area in the Monte San Lorenzo Region (47°S), Southern Patagonian Andes, South America" Arctic, Antarctic, and Alpine Research, 45(1),19-28.

We present the first glacier inventory of theMonte San Lorenzo region (47º35'S, 72º18'W) in the southern Patagonian Andes of Chile and Argentina. This region contains the largest and easternmost glaciers at these latitudes in South America. The inventory was developed using a combination of AST...


Rivera, A.; Bown, F.; Wendt A. and C. Bravo (2012) : "Recent glacier changes in southern Chile and in the Antarctic Peninsula" Anales Instituto Patagonia (Chile), 40(1), 39-44.

In historical times, glaciers in Southern Chile have experienced a significant area reduction mainly in response to ongoing atmospheric warming. Here we present some of the research that has been done by Centro de Estudios Científicos, CECs, Valdivia, during recent years. This research has been ...


Brock, B., F. Burger, A. Rivera & A. Montecinos (2012) : "A fifty year record of winter glacier melt events in southern Chile, 38º-42ºS" Environmental Research letters, doi:10.1088/1748-9326/7/4/045403.

Little is known about the frequency and potential mass balance impact of winter glacier melt events. In this study, daily atmospheric temperature soundings from the Puerto Montt radiosonde (41.43ºS) are used to reconstruct winter melting events at the glacier equilibrium line altitude in the 38...


Willis, M., A. Melkonian, M. Pritchard & A. Rivera (2012) : "Ice loss from the Southern Patagonian Ice Field, South America, between 2000 and 2012" Geophysical Research Letters, L17501, Doi:10.1029/2012gl053136.

A time-series composed of 156 ASTER derived Digital Elevation Models (DEMs) and a radar-penetration-bias corrected version of the Shuttle Radar Topography Mission (SRTM) DEM is used to derive ice surface height and volume changes at the Southern Patagonian Ice Field (SPI) in southern South Americ...
