Satellite remote sensing of glacier flow instabilities (glacier surges)
Glacier flow can be measured through image correlation from repeat spaceborne optical and radar images. The large number of archived satellite data suitable for such work enables development of time series of glacier surface velocity fields with high temporal and spatial resolution. Such results support new insights into glacier instability. Such glacier surges cause ice avalanches, inundate land and infrastructure, dam up temporary lakes, etc.
Study area(s) open and to be discussed, for instance Svalbard, Himalaya, etc.
The work includes: geometric processing of satellite imagery, image correlation, analysis of glacier flow results.
