The robustness of a ray travel-time approach is studied using simulated data in both shallow waters and Arctic oceans. Effects of travel-time measurement error, sound speed profile mismatch, and source/array parameters mismatch on the solution accuracy are quantified. The approach is then employed to analyze the data generated by the first two SUS shots in the ICESHELF-89 experiment. Source location, array depth, array tilting angle, sound speed profile, and bathymetry are characterized.
