The SPLASHIn project (Searching for Pathways and Lakes in Antarctica’s Subglacial Hydrology System using InSAR), aims to increase our observations -and thereby expanding our knowledge- of hydrological processes beneath Antarctica's ice leveraging satellite interferometry (InSAR) techniques based on Sentinel 1 SAR timeseries.
Subglacial hydrology plays a crucial role in controlling ice sheet dynamics and freshwater input into the ocean, yet remains one of the least understood components of the ice sheet system, due to challenges of direct observation and the complexity of underlying processes.
SPLASHIn seeks to advance InSAR-based detection methods to develop a benchmark dataset of subglacial hydrological activity across Antarctica.
The project will also compare InSAR with altimetry-based observations and work towards integrating satellite observations into advanced hydrological modelling, with the opportunity to deepen our understanding of Antarctic subglacial systems. SPLASHIn is funded by the European Space Agency’s Polar Science Cluster.
