FEniCS_ice

----------

**FEniCS_ice is a finite element model framework, 

that quantifies the initialization uncertainty 

for time-dependent ice sheet models.**

FEniCS_ice is a Python code intended for Bayesian quantification of uncertainty 

of large-scale parameter sets within an ice-sheet flow model. 

The implementation consist of a combination of data assimilation and bayesian inference.

This involves 1) inferring unobserved model parameters from data; 2) determining

the uncertainty of the inferred model parameters; 3) running the forward model to make a

prediction about a quantity of interest (e.g. ice mass loss); 4) Propagating the uncertainty 

in the inferred parameters to the model prediction. 

The code contains a dynamic solver for ice-sheet flow which implements the 

Shallow-Shelf Approximation (`MacAyeal et al, 1989.`_)

and approximates parameter covariance using a low-rank approximation to 

the inverse of the cost-function Hessian. The code uses Algorithmic Differentiation 

to find sensitivity of time-evolving Quantities of Interest to parameter sets, 

allowing projections of parameter uncertainty forward in time.
