Recent studies show widespread warming of permafrost and indicate that the Arctic has warmed up to four times faster than the global average. Increasing temperatures initiate a wide range of land-scape and environmental changes, including gradual and abrupt permafrost thaw, vegetation chang-es, and changes in hydrological and fire regimes. Interdisciplinary efforts are needed to further inves-tigate developments in Arctic, boreal, and high-latitude permafrost regions and to better understand the processes and impacts of ongoing changes.
This session is intended as a forum for scientists involved in state-of-the-art research on permafrost disturbance dynamics, associated processes, and impacts. We welcome contributions concerning studies on different scales, from local studies including field observations, near-surface geophysics, and drone measurements, to regional and circumpolar analyses supported by remote sensing tech-niques and modelling approaches. We encourage submissions targeted at dynamic permafrost dis-turbance processes, including thermokarst, coastal erosion, anthropogenic impacts, hydrology, mass movements, sediment fluxes, biogeochemical cycling and associated fluxes.
This session seeks abstracts on (1) novel observations of permafrost disturbance-related phenome-na; (2) the impact of permafrost changes on the natural and human environment; and (3) advances and new developments in measurement, modelling, parametrization, and understanding of perma-frost-related processes.
We particularly encourage contributions that (a) identify processes related to disturbances and envi-ronmental changes in permafrost regions; (b) present novel measurement and monitoring ap-proaches; (c) outline new strategies to improve process understanding; (d) come from or interface with neighbouring fields of science or apply innovative technologies and methods; and (e) investigate model validation, model uncertainty, and scaling issues of diverse processes.
