Airgun Sound with distance. (a) Calibrated sound exposure levels (SEL) in dB re 1 µPa²·s (y-axis), computed from time-domain pressure recordings using 10-second windows (~ 10.7 s between airgun shots), are plotted against distance from the airgun array. (b) Spectrogram with distance. The x-axis represents different recording distances from the airgun array, while the y-axis shows frequencies up to 2500 Hz. The grey scale indicates power in dB, computed from spectrogram power levels. Data recorded on 5th of May.
