The cryosphere presents some of the most challenging environments for scientific research and observation, particularly beneath the surface where critical information is often locked within or beneath inaccessible ice or frozen ground. Nevertheless, climate-driven changes in the structure and function of cryospheric regions have the potential to dramatically impact ecosystems, infrastructure, and communities around the world. Geophysical methods are uniquely capable of mapping, monitoring, and characterizing subsurface properties over a range of scales at high spatial and temporal resolution. In this session, we invite submissions describing innovations, discoveries, and opportunities provided by geophysical observations in the study of glaciers, ice sheets, sea ice, snow, permafrost, and seasonally frozen ground. We welcome contributions applying ground and airborne geophysical field studies and modeling to the characterization, and/or monitoring of cold-region environments and detection of targets within frozen subsurface materials. Studies exploring multidisciplinary approaches, new methodologies, and big-data and machine-learning techniques are encouraged.
