Title:
SOS Antarctica - Slipping Or Shearing in the margins of outlet glaciers in Antarctica
Duration:
01/07/2023 to 30/06/2025
Abstract / short description:
A single ice crystal is mechanically and dielectrically anisotropic and it has been shown that crystals align in macroscopic patterns. This will influence the rheology of ice, one important process needed to project the future evolution of ice sheets. This project will investigate the role of ice anisotropy in shear zone formation and ice-shelf buttressing. It operates at the process level and investigates one of the few mechanisms which allow rapid changes in ice sheet geometries. Our main instrument is a Terrestrial Radar Inteferometer which can detect ice motion at the cm level. We aim to use tidal modulation of Antarctic ice shelves as a diagnostic tool to delineate zones of non uniform ice rheology.
