9. Bounds on
the calving cliff height of marine terminating glaciers
Yue Ma, Cory
S. Tripathy, Jeremy N. Bassis
• We
simulated tensile and shear failure within idealized glaciers using a
full-Stokes ice dynamics model
• Surface
and basal crevasses intersect when rapidly sliding glaciers thin to buoyancy,
and shear failure occurs when ice thickness is large
• Tensile
and shear failure mechanisms together provide lower and upper bounds on
permissible ice thickness for any given water depth
