Fram Strait - NOAA PMEL 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 07:31 PM | Dataset Last Updated: November 07, 2024 at 12:00 AM
This record represents the hybrid millidecade (HMD) sound levels derived from calibrated passive acoustic data. Daily HMD at 1 minute resolution were created using standalone MANTA software (v9.6.13). Sound levels are calculated at 1 Hz resolution up to 435 Hz and then at millidecade frequency bands above 435 Hz. Details on the hybrid millidecade calculation can be found in Martin et al (2021). The source audio data were recorded using Autonomous Hydrophones deployed in the Fram Straight by NOAA's Pacific Marine Environmental Laboratory (PMEL) and the Alfred Wegener Institute.
