Resumen
Annual monitoring of the Monte Perdido glacier (Spanish Central Pyrenees ) started in 2011 using a terrestrial laser scanner. This technique has enabled to measure changes in ice volume during the 2011-12 and 2012-13 seasons. Both years were characterized by highly contrasted climatic conditions. The results show a rapid response of the glacier to the dominant weather conditions each year. The first year, the glacier front retreated clearly and a widespread decline in ice thickness was observed, which on average was 1.8 meters with local losses of more than five meters. During the second year, the favorable conditions for the glacier led to an average increase of ice thickness of 0.43 meters, but the ice variation showed marked contrasts between the proximal areas (where thickness was lost) and the areas close to the bergschrund (where the ice thickness increased more than three meters). Considering the two years, the glacier has lost about one meter thick on average. However, in areas near the glacier bergschrund ice thickness increased up to four meters.
