Detecting Ice Sheet Changes via Optical Image Differencing


NASAThis project is funded by NASA grant NNG06GA60G

Objective

To investigate the possible insights that may be provided by careful subtraction of similarly-illuminated and processed satellite images

Collaborators

Ted Scambos

Project Summary

Recent work has indicated that the approach is useful for detecting elevation uplift or lowering due to sub-glacial lake filling and draining. The image shows promise as a confirmation tool for ICESat-measured elevation changes, by indicating the exact extent of the elevation change detected by ICESat's laser profiles.
