- The AA. review the literature that has contributed to our understanding of patterns, processes and feedbacks, and the environmental consequences of thermokarst, focusing on hillslope, thaw lake and wetland processes. Advances in remote sensing
- techniques, and their application in a broad suite of change detection studies, indicate recent increases in the rates and magnitude of thermokarst. Field-based studies and modelling have enhanced the knowledge of processes and feedbacks associated
- with warming permafrost, changes in talik geometry and accelerated thaw slump activity, and thaw lake expansion. Thermokarst research provides an important context for studying the environmental implications of permafrost degradation. Investigation
- of the interactions between thermokarst and hydrologic and ecological processes has improved knowledge of the feedbacks that accelerate change or lead to stabilisation in terrestrial and thaw lake environments. Finally, the influence of permafrost thaw on soil carbon
- dynamics will be an important focus of thermokarst research because of feedbacks with the global climate system.

- Observations and measurements were made of physical and ecological changes that have occurred since 1985 at a tundra site near Healy, Alaska. Air temperatures decreased (1985 through 1999) while permafrost warmed and thawed creating thermokarst
- temperatures and ground-ice distribution on active-layer dynamics and thermokarst, and the impacts of thermokarst terrain on water redistribution, peat accumulation and shifting vegetation composition. The results provide insights into the processes, dynamics
