ONMS Sound Hybrid Millidecade Spectra

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 05, 2026 at 08:54 PM | Dataset Last Updated: February 05, 2024 at 12:00 AM
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).
