Seismic noise interferometry and distributed acoustic sensing (DAS): inverting for the firn layer S-velocity structure on Rutford Ice Stream, Antarctica

Abstract:

Firn densification profiles are an important parameter for ice-sheet mass balance and palaeoclimate studies. One conventional method of investigating firn profiles is using seismic refraction surveys, but these are difficult to upscale to large-area measurements. Distributed acoustic sensing (DAS) presents an opportunity for large-scale seismic measurements of firn with dense spatial sampling and easy deployment, especially when seismic noise is used. We study the feasibility of seismic noise...
