A workshop on Glacial Isostatic Adjustment, Ice Sheets, and Sea-level Change – Observations, Analysis, and Modelling will be held at the Canadian Museum of Nature in Ottawa, Canada on 24-26 September 2019. The workshop is sponsored by SCAR's Solid Earth Response and influence on Cryosphere Evolution (SERCE) Scientific Research Programme, Polar Knowledge Canada (POLAR), and the Canadian Museum of Nature.
*Please note: This is a different course to the Glacial Isostatic Adjustment course being offered in August 2019, details of which are available here.*
Glacial Isostatic Adjustment (GIA) is the response of the solid Earth to past and present-day changes to glaciers and ice sheets. It generates crustal displacements, sea-level changes, and changes to the Earth’s gravitational field. Recent developments in GIA modelling include increased consideration of lateral variations in Earth structure (i.e. three-dimensional Earth models) and coupled ice-sheet/Earth modelling. Complementing these recent developments are ongoing investigations into paleo ice sheet extent, Earth structure, and paleo sea-level investigations. Geodetic measurements of crustal motion and gravitational change include the GIA viscoelastic response to past changes, as well as the Earth’s elastic response to present-day ice mass changes.
This workshop invites 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. Contributions related to both polar regions are welcomed.
The workshop will emphasize recent developments in GIA and ice sheet modelling:
- coupled ice-sheet/GIA models to explore interactions, including those that may accelerate or impede rapid delivery of ice to the oceans;
- GIA modelling with complex Earth models that may incorporate lateral heterogeneity (i.e., three-dimensional Earth models) and non-linear rheologies.
We also seek contributions on:
- Observations constraining ice sheet history and refinements or syntheses of paleo-sea-level histories;
- Glacial isostatic adjustment modeling to explain aspects of the paleo record (ice-sheet extent, sea-level history) and present-day measured crustal motion and gravitational changes;
- Geophysical and geodetic constraints on Earth structure and mantle rheology beneath present-day and ancient ice sheets;
- Ice sheet and glacier measurements and modelling of past, present, and future extent and volume.
Registration is free, but we need to know your name and contact information. Registration will be first come, first served, and will end when we reach capacity, or on April 30, 2019. Please register via the GIA Workshop Registration Form.
Abstract Submission is open. Attendees may submit more than one abstract. The preference is for oral presentations, but limited poster space will be available. Notification of acceptance of abstracts will be provided by email after abstract submission is closed on April 30. Submit your abstract via the GIA Workshop Abstract Submission Form.
