Variational Inference at Glacier Scale
Douglas J. Brinkerhoff
We characterize the complete joint posterior distribution over spatially-varying basal traction and and ice softness parameters of an ice sheet model from observations of surface s…
Constraining subglacial processes from surface velocity observations using surrogate-based Bayesian inference
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
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 t…
Development of a finite element firn densification model for converting volume changes to mass changes
Evan Cummings, Jesse Johnson, Douglas Brinkerhoff
In regions where ice sheets are increasing in mass, there is a 50-200 m layer of old snow called firn which does not melt in the summer months. The density of firn tracks the trans…
