    • ONMS Sound Hybrid Millidecade Spectra

    Metadata Updated: March 1, 2024

    These data are hybrid millidecade (HMD) spectra of underwater sound levels derived from calibrated passive acoustic recordings collected by NOAA's Office of National Marine Sanctuaries Sound Monitoring Program. Daily HMD at 1 minute resolution were created using standalone software that implements standard methods to promote comparability across datasets while balancing constrained volume and adequate resolution of acoustic spectra (Martin et al., 2021a,b).
