Ice-rich permafrost degradation promotes thermokarst development and may lead to thermokarst lake initiation in vast arctic and boreal lowland regions. Potential impacts and feedback mechanisms on Arctic geomorphology, hydrology, ecology,
biogeochemical cycles, energy-water balance, floral and faunal change as well as human interaction are complex. As thermokarst lakes are expected to play a key role in the permafrost-climate feedback loop, there is an urgent need
(1) to enhance the understanding of limnological, biogeochemical, physical and ecological processes and (2) to discuss their influence on the Earth system across a range of spatial and temporal scales.
This session highlights the role of thermokarst lake dynamics on Quaternary to modern time scales from local to global perspectives. We welcome contributions from field-based studies on lake sediments, gas measurements, monitoring programs,
remote sensing, modelling, data synthesis approaches, and especially interdisciplinary efforts combining natural and social sciences in thermokarst lake research.
