Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Antarctica Roughness Radio-echo sounding Ice dynamics Mö ller Ice Stream Institute Ice Stream
2014/5/20
We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We asses...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data

We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...

Subglacial bed conditions exert a signif i cant control on
ice stream behavior and evolution, and can be characterized
by determining bed roughness from FFT analysis of r adar-imaged basal reflector...
