Ice shelf rift propagation: stability, three-dimensional effects, and the role of marginal weakening

Stress intensity factor solutions for rifts in a square ice shelf B. P. Lipovsky

Short summary
Ice shelves promote the stability of marine ice sheets and therefore reduce the ice sheet contribution to sea level rise. Ice shelf rifts are through-cutting fractures that jeopardize this stabilizing tendency. Here, I carry out the first-ever 3D modeling of ice shelf rifts. I find that the overall ice shelf geometry – particularly the ice shelf margins – alters rift stability. This work paves the way to a more realistic depiction of rifting in ice sheet models.
