  1. Given are: maximum peak-peak (pp, dB re 1 μPa); number of signals within 3 dB of maximum pp; number of signals > 200 dB re 1 μPa pp; maximum sound exposure level (SEL, dB re 1 μPa2.s); SEL within 3 dB of maximum SEL; number of signals > 180 dB re 1 μPa2.s SEL; maximum cumulative SEL (SELcum, dB re 1 μPa2.s); median SELcum. Counts of shots exceeding a threshold were for the pot with the highest value.
