    • Fin Whale Sound Production Recorded at SanctSound Site MB01_09

    Metadata Updated: January 1, 2024

    This record represents fin whale calls detection from raw passive acoustic data. Daily presence of fin whale 20 Hz pulses was detected by analysts and logged using Triton's Logger remora. When hourly background noise levels in the 31.5 Hz octave band exceeded 95 dB, the noise was considered too high to reliably detect calls. These periods were marked as no effort, leading to ratio of effort per day, with 0 being no effort and 1 being 24 hours effort. The settings of the Long-Term Spectral Average (LTSA) used to scan for calls were: window length = 1 h, frequency range = 0-250 Hz, Brightness = 15-20 dB, Contrast = 250%.These data were recorded at SanctSound Site MB01_09 between August 11, 2021 and November 21, 2021.
