Passive Acoustic Data Collection

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 13, 2017 at 12:00 AM
The collection and analysis of passive acoustic data supports research into the soundscape of marine environments. Primary uses include detecting and characterizing sounds produced and used by living marine resources, natural sources of noise from physical oceanographic processes, and anthropogenic noise sources that contribute to the overall ocean noise environment. This analysis supports a wide range of activities including marine mammal stock assessments, monitoring of earthquake and geological activity, and assessing impacts of anthropogenic noise on marine life. The goal of this collection is to steward an accessible national archive of passive acoustic data available to researchers and the public, and to assist NOAA in meeting their data management and accessibility requirements.
