Ice-stream stability on a reverse bed slope

  author={Stewart S. R. Jamieson and Andreas Payne Vieli and Stephen J. Livingstone and Colm {\'O} Cofaigh and Christopher R. Stokes and C. Hillenbrand and Julian A. Dowdeswell},
Marine-based ice streams whose beds deepen inland are thought to be inherently unstable1–3. This instability is of particular concern because significant portions of the marinebased West Antarctic and Greenland ice sheets are losing mass and their retreat could contribute significantly to future sea-level rise4–7. However, the present understanding of icestream stability is limited by observational records that are too short to resolve multi-decadal to millennial-scale behaviour or to validate… CONTINUE READING
