Space-time monitoring of seafloor velocity changes using seismic ambient noise

This deposit contains source code (for time-lapse inversion) and relevant data for reproducing figures in the manuscript entitled "Space-time monitoring of seafloor velocity changes using seismic ambient noise".  Please see the readme file in the directory. 

(0) source code for elastic-wave-equation based time-lapse inversion (written in Fortran).

(1) Cross-correlation (CC) functions at an hourly basis across Julian days 1 and 2, 2016, from offshore seismic ambient noise data recorded by ocean bottom nodes in the Gorgon gas field, Western Australia. 

(2) Relative velocity change (dv/v) measurements.

(3) common-station gathers sorted from hourly CC functions. 

(4) Shear-wave velocity models of the seafloor, including tomographic model from wave-equation dispersion inversion, baseline FWI model, and time-lapse velocity models for Hour 15 Day 1 and Hour 1 Day 2. 

(5) Python plotting scripts.
