Another CEE Trial – and Gervais’ beaked whales!
August 10, 2026
A second controlled exposure experiment trial with simulated Continuously Active Sonar (CAS) was conducted on August 1. In addition to the usual goose-beaked whales, we also had a sighting of less common Gervais' beaked whales.
First CEE Trial of 2026 – and False Killer Whales
July 23, 2026
The Atlantic BRS team had an extremely productive day on Friday, July 17th with tags deployed on both false killer whales and goose-beaked whales, as well as a successful controlled exposure experiment with simulated Continuous Active Sonar signals.
Controlled Exposure Experiment Trial with Simulated CAS Signals
October 1, 2025
On Friday, September 19th, the project team led by Duke University and Southall Environmental Associates conducted a Controlled Exposure Experiment (CEE) trial with goose-beaked whales Ziphius cavirostris in our study area off Cape Hatteras. They generated simulated Continuous Active Sonar (CAS) signals with a brand-new sound source built specifically for this purpose.

Atlantic BRS 2025 - Old Friends & Baby Beaked Whales
June 26, 2025
Field work recently kicked off for the Atlantic BRS project field season and we're happy to say that things appear much more "normal" compared to 2024 when Ziphius were relatively scarce at the Hatteras study site.
Successful CEE Trial with the USS Thomas Hudner
July 24, 2024
In July 2024, the Atlantic Behavioral Response Study, led by Duke University, conducted a successful controlled exposure experiment (CEE) involving the USS Thomas Hudner and tagged goose-beaked whales off Cape Hatteras. The study assessed the whales' behavioral responses to Continuous Active Sonar (CAS) signals, utilizing a High Frequency Recording Package (HARP) for sound recordings and coordination with the USS Thomas Hudner for sonar signal transmission. Preliminary observations suggested minimal behavioral changes in the focal whale, Zc150, during the experiment.
