To collect consistent passive acoustic data simultaneously across all major regions of the US, NOAA and the National Park Service scientists have teamed up to create the Ocean Noise Reference Station Network (NRS).

Through vivid imagery and sound clips, NOAA's story map "Listening to the Sea" explores the NRS and its use of passive acoustic instruments to record sound in the ocean.
