The interaction among magmatic, tectonic and volcanic systems thereof, and ice sheet dynamics in polar regions is a critical, yet poorly known Earth system process with implications for cryosphere evolution and planetary analogs. Understanding each of these components in modern Antarctic and Arctic land and oceans and their confluence over time is critical to decipher the formation and evolution of today’s landscapes from frozen summits to shorelines to the seafloor. These interactions contribute to global fluid, heat, and material cycles that impact ecosystems, including human societies. Inspired by the recent at-sea expedition in the Ross Sea, Antarctica, where a series of new discoveries on the tectono-volcanic seafloor impacted by ice-sheet evolution were reported, this session welcomes contributions from the broader geoscience community who study ice sheet and glacier dynamics interacting with seafloor, coastal, and mountain range landscape, and active processes such as volcanism and tectonics in polar regions. We encourage contributions from field and modeling studies, especially those including using multi-scale, cutting edge technology-based approach, such as LiDAR, Remotely Operated and Autonomously Operated Platforms (e.g. underwater ROVs and AUVs), high resolution imagery analyses (from Satellite to near-source), robotic drilling/sampling, and aero-geophysics.
