ONMS_MB05_20241107-20250407_HMD part of ONMS Sound Hybrid Millidecade Spectra

Description

To understand natural and anthropogenic sound in the ocean, and to compare underwater soundscapes globally, standard methods of analysis must be applied to passive acoustic monitoring (PAM) data. Methods that balance constrained volume and adequate resolution of acoustic spectra have recently been published (Martin et al., 2021a,b). This record is part of a collection of results from this standardized analysis of PAM data, specifically calculation of hybrid millidecade (HMD) spectra of sound levels derived from calibrated passive acoustic data from a long-term monitoring effort in the U.S. national marine sanctuary system. Daily HMD at 1 minute resolution were created using standalone MANTA software (v9.6.15). These data were recorded at MB05 between November 7, 2024 and April 7, 2025.
