MARC recordRock moisture data from Livingston Island (maritime Antarctic) and implications for weathering processes / Kevin Hall.
| Title: | Rock moisture data from Livingston Island (maritime Antarctic) and implications for weathering processes / Kevin Hall. |
| Author(s): | Hall, Kevin. |
| Date: | 1993. |
| In: | Permafrost and Periglacial Processes. (1993.), Vol. 4(3) (1993) |
| Abstract: | Rock moisture content was determined for rock samples from different aspects of rock outcrops during summer. Because of dominant rain-bearing northerly winds, southern aspect usually had lower rock moisture levels, but during periods of snowmelt these levels were high as snow accumulates on southern (lee) side, of outcrops. Wetting and drying are more frequent on northern exposure. Freeze--thaw does not appear to be major factor in summer as rock temperatures rarely drop below 0°C. Rock moisture levels may support rock damage due to segregation ice during winter freeze, when rate of freezing is slowed by overlying snow cover. |
