To import bedrock elevation map from Grab et al. (2021) instead of deriving it?

BedElev_cr = SurfElev_cr .- IceThick_cr0

I suggest that the bedrock elevation map is directly downloaded from https://www.research-collection.ethz.ch/handle/20.500.11850/434697, rather than calculated as above. The folder 07_GlacierBed_SGI provide already cropped bedrock map for individual glaciers.

Then, maybe, you should rather calculate the ice thickness as IceThick = SurfElev- BedElev, since the ice thickness will evolve with time, whereas the bedrock elevation not, and should thus be considered as a reference.
