Methods that balance constrained volume and adequate resolution of acoustic spectra have recently been published (Martin et al., 2021a,b). A community effort supported by NOAA, BOEM, U.S. Navy, and ONR was initiated to apply these methods to PAM datasets from around the world. These records are hybrid millidecade (HMD) spectra of sound levels derived from calibrated passive acoustic data. Daily HMD at 1 minute resolution were created using standalone MANTA software (v9.6.14) from ESONS sites. onGoing Passive Acoustic Data Manager DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce Passive Acoustic Data Manager 325 Broadway, Mail Code E/NE42 Boulder CO 80305-3328 USA pad.info@noaa.gov pointOfContact NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ngdc.noaa.gov/mgg/pad/browse/ESONS-HMD.png Representative hybrid millidecade spectra image png Earth Science > Biological Classification > Animals/Vertebrates > Fish Earth Science > Biological Classification > Animals/Vertebrates > Mammals > Cetaceans Earth Science > Oceans > Ocean Acoustics Earth Science > Oceans > Aquatic Sciences > Fisheries Earth Science > Oceans > Marine Environment Monitoring Earth Science > Oceans > Ocean Acoustics > Ambient Noise Earth Science > Biosphere > Aquatic Ecosystems Earth Science > Biosphere > Ecosystems > Marine Ecosystems theme Global Change Master Directory (GCMD) Science Keywords 2024 revision 19 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

To efficiently tackle large datasets, MANTA is designed around a parallel-processing Matlab package, Raven-X (Dugan et. al., 2014, 2016, and 2018) that uses ordinary multi-core computers to accelerate processing speeds. MANTA calculates the sound pressure spectral density (PSD) levels in units of 1 µPa^2/Hz using Welch's Method in Matlab. The Discrete Fourier Transform length is equal to the sample rate, a Hann window of equal length is applied to the data and 50% overlap is used. This results in PSD estimates of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz and temporal resolution of 1 second. The 120 PSD estimates from each 1-minute segment were averaged, and the average spectrum for each minute was further processed to a hybrid millidecade (HMD) spectrum as dB re 1 µPa^2/Hz, as defined in Martin et al. (2021b). Hybrid millidecades are an efficient means of storing PSD spectra from high sample rate audio files using 1-Hz values up to 435 Hz, then millidecade wide PSD values up to one half of the sampling rate (Martin et al., 2021b). The MANTA outputs for each day are: (1) CSV of the 1 minute HMD results; (2) image of the daily long-term spectral average based on the 1 minute HMD results, (3) image of the daily spectral probability density with percentiles, and (4) NetCDF containing products 2 and 3 in addition to a deployment-level MANTA Metadata output file containing the associated frequency-dependent calibration data used to compute the calibrated spectrum levels. asNeeded Based on the NCEI Metadata Template v1.2 Mooring Platform used to deploy acoustic recorders Loggerhead acoustic recorder
