Journal of Glaciology, 2018 We investigate the appropriateness of calving or crevasse models from the literature using linear elastic fracture mechanics (LEFM). To this end, we compare LEFM model-predicted stress intensity factors (SIFs) against numerically computed SIFs using the ...

Observed meltwater-induced flexure and fracture at a doline on George VI Ice Shelf, Antarctica
Journal of GlaciologyGlobal Navigation Satellite System (GNSS) observations and ground-based timelapse photography obtained over the record-high 2019/2020 melt season are combined to characterise the flexure and fracture behaviour of a previously formed doline on George VI ...

Annals of Glaciology, 2019 GPS measurements of tidal modulation of ice flow and seismicity within the grounding zone of Beardmore Glacier show that tidally induced fluctuations of horizontal flow are largest near the grounding line and decrease downstream.

Annals of Glaciology, 2019 Glacial seismicity provides important insights into glacier dynamic processes. We study the temporal distribution of cryogenic seismic signals (icequakes) at Holtedahlfonna, Svalbard, between April and August 2016 using a single three-component sensor ...

Structural glaciology of Isunguata Sermia, West Greenland
Journal of Maps, 2018 We present a 1:42,000 scale map of Isunguata Sermia, a land-terminating outlet glacier draining the western-sector of the Greenland Ice Sheet. Structure-from-Motion software applied to ∼3,600 aerial images collected by a fixed-wing unmanned aerial ...

The CryosphereAbstract. Crevasse depth calculations with the zero stress approximation or linear elastic fracture mechanics are used in many applications, including calving laws, determination of stable cliff heights, shelf vulnerability to collapse via hydrofracture, and damage evolution in ice.

Horizontal force-balance calving laws: Ice shelves, marine- and land-terminating glaciers
Journal of GlaciologyPredicting calving in glacier models is challenging, as observations of diverse calving styles appear to contradict a universal calving law. Here, we generalize and apply the analytical Horizontal Force-Balance fracture model from ice shelves to land ...

Assessing future ice shelf hydrofracture vulnerability in the ISMIP6 ensemble
Journal of GlaciologyUnderstanding the possibility of future ice shelf collapses similar to that of the Larsen B is critical for improving sea-level-rise projections due to the restraint on upstream flow that ice shelves provide.
