Geodetic Constraints and Modeling of Glacial Isostatic Adjustment and Cryospheric Deformation Across Time Scales
On the occasion of the IAG Scientific Assembly, which will take place from September 1 to 5 in Rimini, Italy, we cordially welcome you to contribute to the following session:
G04-1: Geodetic Constraints and Modeling of Glacial Isostatic Adjustment and Cryospheric Deformation Across Time Scales
This session invites presentations that focus on geodetic constraints and models of glacial isostatic adjustment (GIA) and cryospheric loading deformation in currently and formerly glaciated regions. Traditionally, cryospheric deformation of the solid Earth has been divided into two categories: deformation caused by ice-loading changes several thousands of years ago (~GIA) and deformation due to present-day ice mass changes (~elastic). However, this division is insufficient to explain cryospheric deformation in certain regions. In recent years, increasing attention has been given to the viscoelastic deformation of the solid Earth in response to load changes over decades and centuries. A key challenge lies in addressing deformation across various time scales, ranging from several millennia to centuries and even months. Submissions may discuss advancements in models representing the GIA process across both short and/or long-term time scales. This may include modelling of elastic and viscoelastic signals, studies of low viscosity regions experiencing ice mass change, and assessments of 3D mantle structure and/or transient rheologies. In addition, the session welcomes contributions on present geodetic observations that constrain recent changes to the cryosphere, particularly those contributing to a better understanding of GIA deformation. Submissions that explore the impacts of recent cryospheric changes on environmental indicators, including the influence of GIA and its uncertainties on quantifying present-day changes, are also encouraged, as are contributions focusing on longer-term aspects of GIA in previously glaciated regions.
You can submit your abstracts via https://eventi.unibo.it/iag2025/abstract-guidelines until March 15.
Holger Steffen et al. will give an invited presentation about “A New Generation of Land Uplift and Glacial Isostatic Adjustment Models for Northern Europe”.
We are very much looking forward to your submissions!
Kind regards from Karen Simon, Matthias Willen, Carsten Ludwigsen, Lambert Caron, Ingo Sasgen
