Tafoni development in a cryotic environment: an example from Northern Victoria Land, Antarctica.

The article provides information concerning the processes involved in the growth of tafoni in a cryotic environment, and the relationship of these processes to climate, with particular attention to the thermal regime and the role of wind. The data presented in the study suggested that there is no single key factor that drives the tafoni development. Moreover, the data also confirm that other thermal processes are not really effective for the development of tafoni in this area. The wind speed measured within the tafoni is half that recorded outside, thus favouring snow accumulation within the tafoni and therefore promoting salt crystallization.
