Antarctic Ice Properties Revealed From Teleseismic P Wave Coda Autocorrelation

Pham, Thanh-Son; Tkalčić, Hrvoje


Antarctica is largely covered by an ice cap of a variable thickness characterized by relatively low density and seismic velocities. Passive seismological deployments have a limited use in imaging a thin ice layer because of the dominance of a relatively low‐frequency content in the teleseismic wavefield. Here we use passive seismological data and an improved autocorrelation method utilizing P wave coda to image the ice cover. The resulting autocorrelograms are interpreted as reflectivity...[Show more]
