Rates of rock surface lowering, Princess Elizabeth land, Eastern Antarctica

Abstract

AbstractA series of micro‐erosion‐meter sites on different rock types and in differing wind regimes was established and re‐read after four years on two sites in the Larsemann and Vestfold Hills. These two oases in Eastern Antarctica are subjected to both wind abrasion and salt wedging. The measurements displayed bimodal distributions, indicating that both abrasion and single‐grain detachment could be observed. Surface lowering rates of 0·015 and 0·022 mm a−1 were demonstrated for the Larsemann and Vestfold Hills, respectively.
