Long-term glacier elevation changes

Glacier mass change is an important indicator of climate change, though long-term, spatially-distributed observations of glacier mass changes are relatively scarce. Historic DEMs over areas such as Alaska have large errors, especially in the accumulation areas of glaciers, though modern image processing techniques allow for the reprocessing of historic imagery for detailed observations of past glacier elevations.

Using aerial photos and satellite images collected over Alaska between ca. 1945 and the present, you will estimate volume and mass changes of glaciers in Alaska in order to better constrain the long-term changes taking place.

The work includes: geometric processing of satellite and aerial photos, DEM analysis, and analysis of glacier elevation changes.
