2015 Glacial Isostatic Adjustment Training School

 

13-19 September 2015
Gibralter Island, Lake Erie, USA


Overview

A training school focused on exploring glacial isostatic adjustment (GIA) modeling was held from 13-19 September 2015 at the Ohio State University's Stone Laboratory on Gibralter Island, Lake Erie. The school was aimed at early-stage researchers from a wide range of backgrounds.  Participants were given intensive training on GIA modeling and relevant processes, including ice mass change, solid-earth deformation, and sea-level and geoid variations.  An introduction to the fundamentals of GIA modeling, including model inputs, methods, and current state of GIA models was discussed.  Students learned about relevant data used to generate, tune, and constrain GIA models, including geologic/geomorphologic and ice core records, GPS, seismic, tide gauge, satellite gravity, and satellite altimetry.  The program included both lectures and computer exercises utilizing freely available modeling software, and participants left with an understanding of the theory and development behind GIA modeling as well the practical ability to independently install and run GIA modeling software.
