Constraining subglacial processes from surface velocity observations using surrogate-based Bayesian inference

no code implementations22 Jun 2020 Douglas Brinkerhoff, Andy Aschwanden, Mark Fahnestock

Basal motion is the primary mechanism for ice flux outside Antarctica, yet a widely applicable model for predicting it in the absence of retrospective observations remains elusive.

Velocity variations at Columbia Glacier captured by particle filtering of oblique time-lapse images

no code implementations15 Nov 2017 Douglas Brinkerhoff, Shad O'Neel

We develop a probabilistic method for tracking glacier surface motion based on time-lapse imagery, which works by sequentially resampling a stochastic state-space model according to a likelihood determined through correlation between reference and test images.
