ANNUAL GLACIOLOGICAL SURVEY OF ITALIAN GLACIERS (2021) CAMPAGNA GLACIOLOGICA ANNUALE DEI GHIACCIAI ITALIANI (2021)

The annual glaciological survey (2021) conducted on Italian glaciers is here presented. About 200 volunteers operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group). One hundred and one glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of fourtynine glaciers. Twenty-seven and fifty-two glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (seventeen and fourtyfour of which were measured, respectively). Data for seventeen Italian glaciers monitored during the 2020-2021 hydrological year are reported in the section on mass balance measurements: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), twelve in the Eastern Alps (two in the Lombardy Sector, the other ten glaciers in the Triveneto Sector) and one in the Central Apennines).
