The National Science Foundation (NSF) awarded a 3-year, $184,798 Project Grant under its Polar Programs (CFDA 47.078) to The Research Foundation For The State University Of New York, doing business as Stony Brook University. This collaborative research project will analyze seismic data collected across Antarctica over the past two decades to investigate temporal variations in the physical properties of the Antarctic ice sheets. Key research activities include:
- Analyzing body-wave receiver function waveforms and their vertical-to-horizontal amplitude ratios to investigate shear velocity changes in the top meters to kilometers of the ice sheet.
- Conducting surface wave analysis using both ambient noise and teleseismic earthquakes to constrain temporal changes in the top tens of meters down to tens of kilometers depth, including the ice sheet base and underlying crust.
- Characterizing subglacial hydrological systems through ambient noise coda analysis.
The research aims to provide insights into how Antarctic ice sheet dynamics and subglacial conditions are responding to climate change, with implications for future sea level rise predictions. The project will also support the training of female graduate students and early career faculty.
