Ice streams are warmed by shear strain, both vertical shear near the bed and lateral shear at the margins. Warm ice deforms more easily, establishing a positive feedback loop in an ice stream where fast flow leads to warm ice and then to even faster

Tidal and spatial variability of flow speed and seismicity near the grounding zone of Beardmore Glacier, Antarctica

Autor: Jade Cooley, Paul Winberry, Michelle Koutnik, Howard Conway

Publikováno v: Annals of Glaciology, Vol 60, Pp 37-44 (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. Seismic activity is

A new model of dry firn-densification constrained by continuous strain measurements near South Pole

Autor: C. Max Stevens, David A. Lilien, Howard Conway, T. J. Fudge, Michelle R. Koutnik, Edwin D. Waddington

Publikováno v: Journal of Glaciology, Pp 1-15

Converting measurements of ice-sheet surface elevation change to mass change requires measurements of accumulation and knowledge of the evolution of the density profile in the firn. Most firn-densification models are tuned using measured depth–dens

Over the past 60 years, scientists have strived to understand the past, present and future of the Antarctic Ice Sheet. One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are c
