Short summary
This study explores the capacity to apply ambient noise interferometry to passive seismic recordings in glaciers. Green's function between two seismometers represents the impulse response of the elastic medium. It can be approximated from cross-correlation of random seismic wave fields. For glaciers, its recovery is notoriously difficult due to weak ice seismic scattering. We propose three methods to bridge the gap and show the potential for passive seismic imaging and monitoring of glaciers.
