The cryosphere presents some of the most challenging environments for scientific research and observation, particularly beneath the surface where critical information is often obscured by ice or frozen ground. Nevertheless, climate-driven cryospheric changes are actively impacting ecosystems, civil infrastructure, and communities around the world. Geophysical methods are uniquely capable of mapping, monitoring, and characterizing subsurface properties at high spatial and temporal resolution, and thus offer essential information for elucidating, mitigating, and adapting to these acute and long term changes. In this session, we invite submissions describing innovations and discoveries provided by geophysical observations of cold region environments, as well as applied research, including infrastructure damage due to the degrading cryosphere. We welcome contributions applying ground and airborne geophysical field studies and modeling to the characterization, and/or monitoring of cold region subsurface environments. Studies exploring multidisciplinary and multi-sensor approaches, novel and emerging methodologies, and big-data and machine-learning techniques are encouraged.
