Sounds in the Ocean: Fish and Invertebrates

Listen to exemplar sound clips of marine sounds, taken from passive acoustic recorders. We have compiled these sounds to provide examples of the variety and breadth of fish and invertebrate sounds.

Sounds in the Ocean: Environmental and Anthropogenic

Listen to exemplar sound clips of marine sounds, taken from passive acoustic recorders. We have compiled these sounds to provide examples of the variety and breadth of natural and man-made sounds.

Passive Acoustic Research in the Northeast

We use passive acoustic technologies to study the behavior and movements of marine animals, their contribution to the ocean soundscape, and how they are affected by human-made sounds.

This illustration shows the variety of technologies that NOAA Fisheries researchers use to record underwater sounds and study marine animals. The seascape shows bottom- mounted and drifting acoustic recorders, underwater autonomous vehicles, Atlantic cod and humpback whale with tags, and instruments deployed from a NOAA ship and small boat. Colored circles show a zoomed-in view of the instruments and indicate the type of data collected: green for real-time data, orange for archival data, and blue for active NOAA Fisheries studies marine animals by using a variety of technologies to record underwater sounds, including archival passive acoustic recordings (orange), real-time acoustic data collection (green), and active acoustics (blue).

Odontocete Spatial Patterns and Temporal Drivers of Detection at Sites in the Hawaiian Islands

We conclude that long-term passive acoustic monitoring (PAM records) are a valuable resource for documenting cetacean species patterns and contributes insights into the lives of top predators.

Vessel Monitoring Research

We use acoustic recordings from marine protected areas to monitor patterns of vessel presence and identify characteristics of potentially non-compliant vessels to aid local patrolling and enforcement efforts.
