Geophysical Advances in Cryospheric Processes, Structure, and Environmental Change
Session ID#: 74729
Session Description:
The cold regions of our planet are undergoing unprecedented changes; however, many details of cryospheric processes and subsurface characteristics are inaccessible beneath or within frozen Earth materials and thus remain unknown. Geophysical observations are essential to studies of high-elevation and high-latitude cold regions, and through ongoing advancements in instrumentation, computing power, and new measurement strategies, geophysical methods are well positioned to address many open cryospheric research questions. In this session, we seek submissions describing advancements, insights, and opportunities provided by geophysical observations in the study of glaciers, ice sheets, sea ice, snow, permafrost, and seasonally frozen ground. We welcome submissions using ground and airborne geophysical methods (e.g. ground penetrating radar, electrical resistivity, nuclear magnetic resonance, electromagnetic, seismic, gravity etc.) applied to solve cryospheric problems including characterization, detection, and/or monitoring of cold-region environments. Studies exploring innovative methods, multidisciplinary approaches, and the vulnerability of the cryosphere to future changes are particularly encouraged.
