Glacial Isostatic Adjustment: Impacts on Earth's Systems and Sea-Level Dynamics
SCAR and IACS
Convener: Matthias O. WillenECSECS | Co-conveners: Holger Steffen, Jun'ichi Okuno, Valentina R. Barletta, Caroline van Calcar
Glacial Isostatic Adjustment (GIA) refers to the Earth's response to changes in ice sheets, leading to surface deformation, changes in gravity, rotation, and the state of stress. This process is primarily driven by ice-sheet dynamics and Earth's structure, impacting other Earth systems like the cryosphere and hydrosphere. A wealth of standardized observational data, such as GNSS measurements, relative sea levels, and satellite gravimetry, helps refine GIA models. These models enhance our understanding of ice-sheet history, sea-level changes, and Earth's rheology.

We welcome contributions on GIA's effects across various scales, including geodetic measurements, complex GIA modelling, GIA-induced sea-level changes, and the Earth's response to current ice-mass changes. We also invite abstracts on GIA's impact on nuclear waste sites, groundwater, and carbon resources. 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/) and the IAG/IACS sub-commission 3.4 “Cryospheric Deformation”.
