TL;DR: A north-to-south directionality of the abrupt climatic signal is demonstrated, which is propagated to the Southern Hemisphere high latitudes by oceanic rather than atmospheric processes, which confirms a central role for ocean circulation in the bipolar seesaw.
Journal ArticleDOI
Ice flow at low deviatoric stress
Erin C. Pettit,E. D. Waddington +1 more
TL;DR: In this article, the authors studied the effects of a shift in the stress exponent on ice flow using a two-term flow law for isotropic ice and showed that a flow-mechanism shift may occur in low-deviatoric-stress regions near ice divides, resulting in a nearlinear constitutive relationship for ice flow.
Journal ArticleDOI
The role of crystal fabric in flow near an ice divide
TL;DR: In this article, an analytical formulation for anisotropy was incorporated into a non-linear flow law within a finite-element ice-sheet flow model, and the effect of fabric on the large-scale flow pattern near an ice divide was explored.
Journal ArticleDOI
From ice-shelf tributary to tidewater glacier: continued rapid recession, acceleration and thinning of Röhss Glacier following the 1995 collapse of the Prince Gustav Ice Shelf, Antarctic Peninsula
Neil F. Glasser,Ted Scambos,Jennifer Bohlander,Martin Truffer,Erin C. Pettit,Bethan J. Davies +5 more
TL;DR: Glasser, N. F., Scambos, T. A., Bohlander, J., Truffer, M., Pettit, E., Davies, B. J..
Journal ArticleDOI
Boundary condition of grounding lines prior to collapse, Larsen-B Ice Shelf, Antarctica

TL;DR: The authors mapped the sea floor beneath the ice shelf before it fell apart, which revealed that the modern ice sheet grounding line was established around 12,000 years ago and has since remained unchanged, strengthening the idea that surface processes controlled the disintegration of the Larsen Ice Shelf.
