The Over-whale-ming Plastic Problem
Second year PhD student Greg Merrill discusses various impacts of plastic pollution in this article written for the New Security Beat, a blog for the Wilson Center’s Environmental Change and Security Program.
We study the acoustic behavior of marine mammals via collaboration with existing tagging programs and using standalone passive and digital acoustic monitors. This approach enables us to learn about the effects of anthropogenic noise on animal behavior, since sound propagates very efficiently through sea water.
The behavioral ecology of marine animals (e.g., foraging behavior, social behavior and communication) is important to understanding the long-term fitness of a species. Our studies involve tagging programs and observations in the field, as well as predictive modeling in the lab to better protect species of interest.
Oceanographic research relies heavily on data collection technology, especially in this era of increased capabilities of miniaturized electronics and unmanned vehicles. We develop new technologies for marine conservation research ranging from unmanned aerial systems, sensor development, to integrated acoustics.

Lab Member Charles Muirhead coauthors a paper identifying a new population of Blue Whales! Check out the New York Times article to learn more about how the team used acoustic data to distinguish the previously unidentified population.
Check out this post to watch how the Nowacek Lab is working with the U.S. Navy to understand how varying levels of sonar exposure affect whale behavior!
“On February 2-3, the Pratt student group Duke Conservation Tech (DCT) held the second Duke Blueprint Ideathon. As an “ideathon,” Blueprint brings the energy and extremely fast pace of hackathons to students of all academic backgrounds, especially those who are intimidated by the technology focus of other events, to generate
What would you do if you heard the call of a hungry killer whale? Would you stay to fight or would you swim as fast as you could in the other direction? Not sure? Find out how short-finned pilot whales and Risso’s responded in our newest paper Selective reactions to
Last spring, Duke undergraduates Ashley Blawas (Biomedical Engineering), Brandon Dalla Rosa (Electrical & Computer Engineering) and Sam Kelly (Mechanical Engineering) received a Follow-on Student Research Award to improve on the research methods employed by their Bass Connections team History and Future of Ocean Energy. Mentored by Douglas Nowacek, they aim to produce a digital
The Blue Devil Engineering team based out of Duke University is using drones, drop pods and machine learning to map the seafloor. Led by Professors Martin Brooke, Tyler Bletsch and Douglas Nowacek, the team is an enthusiastic group of high school, undergraduate and graduate students working together to develop their
Shooting air guns into the ocean could soon be fair game in the search for oil and gas along the North Carolina coast, even if the seismic blasts “harass marine mammals” such as whales. The National Marine Fisheries Service is considering allowing the practice by energy companies and wants the public
Animal behaviour can provide valuable information for wildlife management and conservation. We describe several methods developed by marine mammal scientists to study behaviour, primarily of cetaceans, focusing on technological advances: unmanned aerial systems (UAS), satellite-linked telemetry, passive acoustics and multisensor high-resolution acoustic recording tags. We then go on to explain how the data collected
For a half century a sound heard in the Southern Ocean and beyond has baffled acousticians. The noise – nicknamed “the bio-duck” – appears in the winter and spring. The repetitive, low frequency noise has been recorded many times in the waters around the Antarctic and western Australia. Our paper has
