the experiments are performed in a water tank (see photo) signatures of an S15 watergun fired at different water depths are measured S15 watergun has one cylindrical gun port and is fired at 130 bar signatures are measured in water and air with B&K 8105 hydrophones signatures in air are measured at normal incidence, directly above the source (yr = 0 cm, no "yr" in filename) and at different horizontal offsets from the source (varying "yr" as indicated in the filename) channel 3 is the trigger channel and indicates when the S15 watergun is fired recordings are averaged/stacked measurements of 3 shots with the S15 watergun at each source depth "zs" the filename indicates the source type ("watergun_S15_"), where the signal is measured ("water_" or "air_") and the source depth in water ("zs_cm.txt"), and the horizontal offset ("yr") for the specific experiments more information can be found in the referenced publication and the sketch of the experimental set up
