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.
