Alison F. Banwell, Douglas R. MacAyeal and Olga V. Sergienko Breakup of the Larsen B Ice Shelf triggered by chain reaction drainage of supraglacial lakes Geophysical Research Letters 40

Version of Record online: 27 NOV 2013 | DOI: 10.1002/2013GL057694

Key Points

  • Larsen B Ice Shelf rapidly broke-up by chain-reaction drainage of surface lakes
  • Lake-induced stress set fracture spacing small enough for capsize-driven breakup
  • Lake interaction by flexural stress defines an ice-shelf stability tipping point
