Polar and mountainous regions are evolving rapidly in response to climate change, carrying significant implications for Earth's cryosphere. These changes impact natural hazards, alter the availability of natural resources, and influence global trade dynamics and additional economic factors. The rapid expansion of data collected by broadband seismometers, nodal instruments, and distributed acoustic sensing (DAS) has led to the emergence of a unique interdisciplinary field at the intersection of glaciology and seismology. Observations from seismic and microseismic signals offer valuable constraints for deducing structures and processes within Earth's cryosphere. As a result, our understanding of the complex interconnections within Earth systems and climate dynamics is further enriched. Seismic techniques used in recent studies have provided in-situ quantitative insights to illuminate the dynamics of various cryospheric systems and environments including glacial flow, retreat, iceberg calving, ice shelves, basal and episodic slip, hydrology, and sea ice migration. Active and passive seismic methods allow for analysis and imaging of Earth’s structure in polar and mountainous regions, including glaciers, ice sheets, sea ice and permafrost. Furthermore, seismic methods prove useful for monitoring Earth’s cryosphere, and related phenomena, in a changing world. This session aims to assemble diverse experts to present the latest cryoseismology research and foster collaborations in this emergent field. We welcome a wide range of contributions, encompassing studies that focus on monitoring and analyzing seismicity of tectonic or cryogenic origin, natural hazards, and near-surface processes and structures. We also encourage investigations into tectonic-scale structures and dynamics. Furthermore, we invite submissions that explore the advancement of innovative seismic methods, aiming to enhance monitoring and understanding of Earth's cryosphere. In addition to showcasing excellent science, this inaugural cryoseismology session will help advance SSA’s mission of fostering scientific connections and collaborations within an inherently interdisciplinary field.
