Abstract Basal motion is the primary mechanism for ice flux in Greenland, yet a widely applicable model for predicting it remains elusive. This is due to the difficulty in both observing small-scale bed properties and predicting a time-varying water pressure on which basal motion putatively depends. We take a Bayesian approach to these problems by coupling models of ice dynamics and subglacial hydrology and conditioning on observations of surface velocity in southwestern Greenland to infer the… 
Seasonal evolution of basal environment conditions of Russell sector, West Greenland, inverted from satellite observation of surface flow
Abstract. Due to increasing surface melting on the Greenland ice sheet, better constraints on seasonally evolving basal water pressure and sliding speed are required by models. Here we assess the
A Review of Bayesian Modelling in Glaciology
Bayesian methods for modelling and inference are being increasingly used in the cryospheric sciences, and glaciology in particular. Here, we present a review of recent works in glaciology that adopt
Drainage of an ice-dammed lake through a supraglacial stream: hydraulics and thermodynamics
Abstract. The glacier-dammed Lac des Faverges, located on Glacier de la Plaine Morte (Swiss Alps), has drained annually as a glacier lake outburst flood since 2011. In 2018, the lake volume reached

Brief communication: A roadmap towards credible projections of ice sheet contribution to sea-level
Abstract. Accurately projecting mass loss from ice sheets is of critical societal importance. However, despite recent improvements in ice sheet models, our analysis of a recent effort to project
Early detection and uncertainty quantification of rapid sea-level rise from Antarctica
2. Rationale ​The evolution of the Antarctic ice sheet in response to climate change remains the single largest uncertainty in projecting future sea-level rise (SLR), with risk-averse projections

Topology and pressure distribution reconstruction of an englacial channel
Glacial hydrology describes the way water moves over, through and under glaciers. Meltwater flows every summer over the surface of glaciers and ice sheets, creating pathways down to below the surfa...

Reconstruction of basal properties in ice sheets using iterative inverse methods
Abstract Inverse problems are used to estimate model parameters from observations. Many inverse problems are ill-posed because they lack stability, meaning it is not possible to find solutions that

Direct observations of evolving subglacial drainage beneath the Greenland Ice Sheet
TLDR
The authors' simultaneous measurements of moulin and borehole hydraulic head and ice velocity in the Paakitsoq region of western Greenland show that decreasing trends in ice velocity during the latter part of the melt season cannot be explained by changes in the ability of mOUlin-connected channels to convey supraglacial melt, and suggest that decreasing late-season ice velocity may be caused by changesIn connectivity in unchannelized regions of the subglacial hydrologic system.
