Establishing a global standard for high resolution indicators of periglacial climate

Periglacial phenomena can be used as paleoclimatic indicators, but the conventional indicators have lacked physical basis. This study aims at establishing high resolution indicators of periglacial climate, based on comprehensive field observations of various periglacial processes in different frost conditions and on laboratory simulations of some processes. The observations and experiments permit understanding of the timing and rate of periglacial movements, as well as the environmental and material controls on these processes. Data analysis and modelling focus on the thermal and hydrological regimes of permafrost, thermal controls on solifluction and rock glacier dynamics and thresholds for ice-wedge cracking.
