Misure preliminari sul ghiacciaio settentrionale di Tarn Flat (Terra Vittoria , Antartide)

Preliminars measurements on the northern glacier of Tarn Flat (Victoria Land, Antarctica)

Abstract

The work reports the survey made on a small glacier mainly fed by wind blown snow in the deglaciated area of Tarn Flat, during the 5th italian expedition of the Programma Nazionale di Ricerche in Antartide. A net of 15 stakes has been placed on the glacier to measure, in next years, deformations, velocity and accumulation and ablation rates. To check the position of the snout 5 points have been arranged. The glacier, because of its small size, could give a clear evidence of even weak environmental changes.
