2025 Glacial Isostatic Adjustment Workshop

A workshop focused on glacial isostatic adjustment (GIA), ice sheets, sea-level change, and associated geodetic and geophysical observational constraints will be held at the Institute of Ocean Sciences (IOS) and Pacific Geoscience Centre (PGC), located near Sidney, British Columbia, Canada, from 2-6 June 2025.  The workshop aims to bring together 80-100 researchers of all career stages to discuss recent advances in the observations, analysis, and modelling of GIA.

The 5-day program will follow the general format of oral and poster sessions focused on various thematic topics relating to GIA, ice sheet and glacier history, mass balance and projected future change, and the effects of this ice sheet evolution and Earth response on global, regional, and local scales.  We invite contributions discussing observations, analyses, and modelling of ice sheet dynamics, the ensuing solid-Earth response, the resulting global and local (relative) sea-level changes, and the interactions and feedbacks between these components of the coupled Earth system. 

In addition to oral and poster sessions, the workshop will incorporate opportunities for networking and collaboration, including a one-day field trip to observe local records of GIA, glacial geology, and active tectonics.  During the last day, several smaller workshops on specific topics that are of high interest for the GIA community will be offered. These workshops will allow us to gather groups and advance research in targeted fields (e.g., benchmarking of GIA modelling codes, differences between GIA and GNSS reference frames, modelling of paleo ice-sheet histories, GIA in Antarctica, and observational constraints for GIA in Antarctica). 

Registration, Accommodations, and Financial Support

Abstract submission will open in late 2024 or early 2025.  Instructions for booking accommodations will be provided concurrently.  We anticipate a modest registration fee not to exceed $200 USD.  As part of this registration fee, it is planned that coffee breaks and lunches will be provided.

It is anticipated that travel support for early career researchers will be available, with special consideration given to engaging minorities and individuals from underrepresented groups.  More information, including instructions for how to apply for funding, will be made available late 2024 or early 2025. 

Virtual Participation

To expand the reach and scope of the workshop, a virtual participation option will be offered by streaming of the lectures (free of charge).  The organizing committee is also considering additional means by which virtual participants may engage (e.g., Gather.town).  Instructions for how to participate virtually will be made available in early 2025.
