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).

Vocal Behavior of False Killer Whale (Pseudorca crassidens) Acoustic Subgroups

Better understanding of the vocal behavior of cetaceans in the name of developing automated passive acoustic cetacean tracking, localization, and classification techniques.

Retrospective analysis of measures to reduce large whale entanglements in a lucrative commercial fishery

Marine mammal bycatch is a significant anthropogenic threat to recovering populations. Gear reduction in Washington (USA) crab fishery decreased entanglement risk to whales.

An Unknown Nocturnal Call Type in the Mariana Archipelago

In spring/summer of 2018 and 2021, the Pacific Islands Fisheries Science Center Cetacean Research Program deployed drifting acoustic recorders in the U.S. Exclusive Economic Zones surrounding the Mariana Archipelago.

Rice’s Whales in the Northwestern Gulf of Mexico: Call Variation and Occurrence Beyond the Known Core Habitat

We used long-term passive acoustic recordings from the northwestern Gulf of Mexico shelf break to explore the extent of Rice’s whale distribution in the northern Gulf of Mexico and to evaluate whether they exhibit seasonal movements throughout this range.

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.
