Record #176990:

Modelling of rift propagation on Ronne Ice Shelf, Antarctica, and sensitivity to climate change / E. Larour, E. Rignot, D. Aubry.

Title: Modelling of rift propagation on Ronne Ice Shelf, Antarctica, and sensitivity to climate change / E. Larour, E. Rignot, D. Aubry.
Author(s): Larour, E.
Rignot, E.
Aubry, D.
Date: 2004.
In: Geophysical Research Letters. (2004.), Vol. 31(16) (2004)
Abstract: Uses InSAR observations to describe evolution of rifts along Hemmen Ice Rise on Ronne Ice Shelf prior to large calving event of October 1998, and couples these observations with computer model combining viscous flow of ice shelf with linear elastic fracture mechanics description of propagation of rifts. Model shows that ice melange trapped inbetween rifts exerts major control on propagation of rifts, and in turn on ice shelf stability. Melting of ice melange from oceanic or atmospheric warming would significantly increase propagation rate of rifts and threaten ice-shelf stability.
