Figure 5. Diagram of surface elevation, ice thickness, and bed elevation. Bedrock elevation
is computed as the difference of DEM surface elevation and ice thickness values. For example,
if the surface elevation (a) is 400 m above sea level, and ice thickness (b) is 100 m,
the bedrock elevation (c) is 300 m above sea level (c = a - b).
