Data sets

Synthetic-aperture radar (SAR) processed airborne radio-echo sounding data from the Institute and Moller ice streams, West Antarctica, 2010-11 M. Siegert, H. Jeofry, H. Corr, N. Ross, T. Jordan, F. Ferraccioli, R. Bingham, A. Le Brocq, D. Rippin, and C. Robinson https://doi.org/10.5285/8a975b9e-f18c-4c51-9bdb-b00b82da52b8

Short summary

Using airborne ice-penetrating radar we investigated the physical properties and structure of the West Antarctic Ice Sheet. Ice deep beneath the Institute Ice Stream has prominent layers with physical properties distinct from those around them and which are heavily folded like geological layers. In turn, these folds influence the present-day flow of the ice sheet, with implications for how computer models are used to simulate ice sheet flow and behaviour in a warming world.
