A distributed acoustic sensing instrument with a fiber optic array aims to create the first-ever "movie" of ice-structure motion that has been largely hidden from our view. The GLASS project will provide high-resolution seismic measurements at a key region in Antarctica where ice sheets transition from grounded ice to floating ice shelves and will study the influence of grounding line dynamics to basal melting and ice flow. This ground-truth is essential to advancing fundamental research on grounding-zone dynamics and long-term cryosphere monitoring.
In providing ground-truth for remote sensing missions on Earth, GLASS also acts as a potential precursor instrument (low-SWaP DAS) for lunar deployment where it may provide the same ground-truth essential to observe and understand the surface of the Moon.
