Passive Acoustic Research at the Southeast Fisheries Science Center

The Passive Acoustic Ecology Program conducts a variety of research projects that use passive acoustics to assess populations and improve our understanding of cetaceans in the Gulf of Mexico and U.S. waters of the Western Atlantic.

Passive Acoustic Technologies Used at the Southeast Fisheries Science Center

Researchers use advanced technology to record and study the sounds produced by marine mammals and human-made sources.

Geographic variation in Risso's dolphin echolocation click spectra

This study investigates using clicks for species and population identification by characterizing the spectral structure of Risso's dolphin echolocation clicks recorded over wide-ranging geographic regions.

Passive Acoustic Research in the Atlantic Ocean

We use innovative passive acoustic technologies to study the behavior, movements and distribution of marine animals and their contribution to soundscape ecology. We also evaluate how man-made sounds affect marine animals.
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).

Protected Species Gear Research

We work closely with the commercial fishing industry to reduce harmful interactions with marine mammals, turtles, and other protected species.

Developing Viable On-Demand Gear Systems

On-demand gear development continues to evolve with the help of industry.

Borrow From The Northeast Fisheries Science Center Gear Library

The gear library is a collection of on-demand or “ropeless” systems, built with help and donations from environmental and academic organizations, that we lend to fishermen for testing.
