Rock Weathering in Central Spitsbergen
Field studies carried out at Longyearbyen (Spitsbergen, 78º 13 ' N, 15º 36 ' E) and at Terra Nova Bay (Antarctica, 74 ° 41 ' S, 164 ° 07 ' E) question the role of frost action as an efficient rock weathering agent. By carrying out measurements of rock temperature, rock moisture c...

| Summary: | Field studies carried out at Longyearbyen (Spitsbergen, 78º 13 ' N, 15º 36 ' E) and at Terra Nova Bay (Antarctica, 74 ° 41 ' S, 164 ° 07 ' E) question the role of frost action as an efficient rock weathering agent. By carrying out measurements of rock temperature, rock moisture content and Young’s modulus variations in both locations, differences between these environments are explained in terms of climate, rock properties and the implications of these properties on the weathering processes involved. The large variability of polar environments, and its repercussions on particular geomorphological processes like rock decay, are highlighted. 1 |
