Session description (250 word maximum in English):

Ground surface in lowland permafrost regions undergoes vertical movements associated with seasonal freeze-thaw processes, water migration, degradation and aggradation of permafrost including thermokarst process. Such vertical movements, either gradual or abrupt, affect ecosystems and carbon cycles, hydrologic and landscape processes, infrastructure stability, and living conditions in cold regions.

This session invites contributions on thaw subsidence and frost heave, aiming to quantify and understand (1) their magnitude and variability across multiple spatial and temporal scales, (2) their links with soil properties, vegetation dynamics, thermal and hydrological processes, climatic changes, anthropogenic disturbance, etc., and (3) their environmental and socio-economic impacts. This session aims to offer a platform for experts from multi-disciplinary backgrounds to share and exchange and welcomes studies using laboratory measurements, in situ observations, remote sensing, geodesy, modeling, and engineering practices. Studies conducted by the IPA Action Group “Towards a Permafrost Thaw Subsidence Product within the GTN-P database” are particularly encouraged.
