Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 05, 2026 at 08:04 PM | Dataset Last Updated: June 15, 2023 at 12:00 AM
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_08 between April 23, 2021 and June 08, 2021.
