Spatio-temporal variability of processes across Antarctic ice-bed-ocean interfaces

Understanding how the Antarctic ice sheet will respond to global warming relies on knowledgeof how it has behaved in the past. The use of numerical models, the only means toquantitatively predict the future, is hindered by limitations to topographic data both now andin the past, and in knowledge of how subsurface oceanic, glaciological and hydrologicalprocesses interact. Incorporating the variety and interplay of such processes, operating atmultiple spatio-temporal scales, is critical to modeling the Antarctic’s system evolution andrequires direct observations in challenging locations. As these processes do not observedisciplinary boundaries neither should our future research.
