Caratteri delle modificazioni areali di livello e volumetriche per il ghiacciaio del Cereser (Alpi centrali, gruppo Ortles-Cevedale), 1990-1997 – Characteristics of area, elevation, and volume changes in the Careser Glacier (Central Alps, Ortles-Cevedale Group)

Abstract

An aerial survey carried out in Sept ember 1997 on the Careser Glacier allowed comparison with the previous surve y of 1990 and also evaluation of area , elevation, and volume chan ges during this period. In addition, computerized 1:5000 th ematic map with isoline s representing elevation variations was prepared. Elevation variations for 1990-1997 were negative at all altitudes between 2860 and 3330 m a.s.l. , with a mean value of -7.75 m, corresponding to a volum e of -29.8975 x 10 6 m’ . In the same interval, the overall surface area reduction was nearlv 13%. The distribution of area an-d altitu de changes are analysed on the glacier sur face and compa red with th eir beh aviour in pr evious periods, beginning fram 1967. Results confirm a good fit with contemp or aneous glaciological measurement s on mass balance, and may be considered indicative of th e dynamics of th e present ph ase of accelerated glacier shrinkage in the Alps.
