Enhanced bedrock weathering in association with late‐lying snowpatches: Evidence from Livingston Island, Antarctica
Abstract An indication of the extent of weathering on different aspects of rock outcrops on Livingston Island, Antarctica, was obtained by means of a Schmidt hammer, a cone indenter and measurement of weathering rind thickness. Results show that weathering, particularly chemical weathering, is enhan...
