1D Marine Ice Sheet Flowline Simulator

Toy-model lab for undergraduate MICI intuition on a 1D flowline grid. Explore how cliff freeboard, shelf buttressing, and failure timescale control marine cliff retreat.

B=1 means strong shelf support; B=0 means no buttressing and easier cliff failure.

40 m

Toy-model MICI activates when grounded marine cliff freeboard exceeds F_c.

1.20 yr

Smaller tau gives faster cliff retreat once instability starts.
