How to Analyze a Glacier via Gradient-Based Optimization

Nathan Martin July 17, 2018

Following up on a previous blog post about glacier flow modeling, we are going to delve a bit further into a crucial component of geophysics modeling in general: parameterizing numerical models using observations. Let’s see how we can quantify sensitivity and infer unknown parameters through indirect observations using the COMSOL Multiphysics® software and add-on Optimization Module.

In a 2013 report, the Intergovernmental Panel on Climate Change stated that Earth’s cryosphere is “a natural integrator of climate variability and provides some of the most visible signatures of climate change.” (Ref. 1) The cryosphere is the part of the climate system that contains frozen water and makes up 80% of our fresh water. Using the COMSOL Multiphysics® software, we can simulate classical ice flow to analyze cryosphere dynamics and assess climate change effects such as rising sea levels.
