The dynamic response of the solid Earth to the waxing and waning of ice sheets and corresponding spatial and temporal sea-level changes is termed Glacial Isostatic Adjustment (GIA). This process, like solid Earth tides, oceanic load tide, other short-period surface loading (e.g., continental water), and normal-mode oscillations, causes surface deformation and changes in the gravity field, rotation, and stress state of the Earth. Different types of observational data, now standardized, help constrain highly sophisticated models of the Earth. They also serve as a tool to constrain the rheological properties of the Earth.

We aim to bring together researchers working on GIA, body tides, short-period loading problems, and normal modes with the broad goal of using these various processes to better understand the interior of the Earth and other planets across these wide temporal and spatial scales. This session is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth - Ice - Sea level, in view of instabilities and thresholds in Antarctica (https://www.scar.org/science/instant/home/).
