Investigating mechanisms of subglacial hydrology and basal shear stress beneath Whillans Ice Stream using passive seismology
We propose to operate a six-station passive seismometer network above and near the Whillans Ice Stream, Antarctica subglacial lakes. The seismometers will join permanent GPS stations deployed as part of an ongoing NSF funded project (PI is UC Santa Cruz professor, Slawek Tulaczyk) to provide a uniqu...

| Summary: | We propose to operate a six-station passive seismometer network above and near the Whillans Ice Stream, Antarctica subglacial lakes. The seismometers will join permanent GPS stations deployed as part of an ongoing NSF funded project (PI is UC Santa Cruz professor, Slawek Tulaczyk) to provide a unique dataset related to the subglacial lakes and basal shear stress. Subglacial hydrology and basal shear stress are two important components affecting glacier stability and yet, both are poorly understood. Passive seismology at the surface of an ice sheet is one approach that can remotely detect conditions and active changes at the base of an ice sheet. A supplement to Tulaczyk NSF grant with Susan Schwartz and Emily Brodsky as co-PIs has been submitted to NSF Office of Polar Programs to fund the seismic this work. |
