Resumen:
Monte Tronador (41° 9'38.67"S,
-71°53'6.52" W, 3491 m) is an extinct volcano straddled by the Chile-Argentinean border at the core of
the wet Patagonian Andes. The four major glaciers on the Argentinean side are (north to south): Glaciar Frías, Glaciar
Alerce, Glaciar Castaño Overa and Glaciar Manso (or VentisqueroNegro). Here we present
preliminary results of the first field season in the area intended to conduct
the mass balance of these four glaciers. These activities are part of the
National Glacier Inventory program in Argentina conducted by IANIGLA in
collaboration with other public agencies.
The Monte Tronador glaciers are
among the most studied glaciers in North Patagonia including the
reconstructions of glacier fluctuations over the past 400 years. However, no
mass balance or surface glacier velocity studies have been conducted for these
glaciers. The lack of information on climate-glacier relationships and glacier
dynamics hampers the evaluation of the climate history behind the reconstructions
of glacier fluctuations and, perhaps more importantly, the development of
scenarios of the future evolution of these glaciers. Here we discuss the
strategy followed during the first mass balance measurement at this site, introducing
new approaches to classical glaciological methods. The mass balance results will
be used to calibrate surface energy balance models.
