Project Information
Collaborative Research: Monitoring Antarctic Ice Sheet Changes with Ambient Seismic Noise Methods
Start Date:
End Date:
In this project, the researchers processed and analyzed previously acquired seismic data from the POLENET-ANET array (2010-2011) to estimate variations in seismic shear-wave speed beneath the array. This investigation used a passive seismology method call ambient noise tomography, whereby repetitive seismic noise correlation functions were computed from records of Earth's ambient seismic noise field. The main results indicate a shallower Moho beneath Marie Byrd Land compared to previous studies in the region.
