RESPONSE OF EUROPEAN ROCK GLACIERS TO CLIMATE CHANGE. A COMPARATIVE ANALYSIS OF DOESEN (AUSTRIAN ALPS), POSETS (CENTRAL PYRENEES) AND CORRAL DEL VELETA (SIER RA NEVADA) DURING 2001-2008 PERIOD.

摘要

The study of periglacial geomorphology can inform us of climate changes taking place throughout the Quaternary. Its analysis in the present day indicates the influence of climate on them, and a continuous sequence of its behaviour may even be an indicator of the future development of the rock glacier analyzed. In this paper a comparison is made of three rock glaciers: Doesen (Austrian Alps), Posets (Central Pyrenees) and Corral del Veleta (Sierra Nevada). In these three glaciers annual measurements were taken of horizontal and vertical displacement from the installation in 2001 of monitoring points (nails and rods) to 2008. Geodesic data were not available for the glacier of Doesen in 2003, nor for the Posets glacier in 2002, 2003 and 2004. Soil temperature data from the Corral del Veleta rock glacier were available for all the years of the study period (2001-2008).
