Geographic Distribution of the Cross Seamount Beaked Whale Based on Acoustic Detections

The foraging behavior of Cross Seamount beaked whales appears to be unique among all beaked whales.

Identifying Social Clusters of Endangered Main Hawaiian Islands False Killer Whales

In this study, we used photo-identification data over a 23 year period to reassess the number and membership of social clusters for false killer whales.

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 Differences in Blainville’s Beaked Whale (Mesoplodon densirostris) Echolocation Clicks

We use acoustic recordings collected over broad time and space scales to investigate whether global variability in echolocation frequency could make clear population structure in Blainville's beaked whale.

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.
