Potomac-Chesapeake Dolphin Project

Potomac-Chesapeake Dolphin Project The Potomac-Chesapeake Dolphin Project's (PCDP) mission is to better understand and protect the bottlenose dolphins of the Potomac River and Chesapeake Bay

Very little is known about the common bottlenose dolphins (Tursiops trunctaus) that inhabit the Chesapeake Bay and Potomac River. Yet reports of dolphins in the area date back to the 1800s, with one sighting as far up the Potomac as Washington, DC! While the PCDP research is broadly concerned with better understanding all aspects of these animal's biology, we are focusing our initial efforts on a

few key areas: abundance and distribution, population structure, and social behavior and disease risk. Additionally, as part of our mission to better understand and protect the Potomac-Chesapeake bottlenose dolphins and their ecosystem, we make it a priority to promote environmental stewardship through sound education and community outreach. This portion of our project is just getting started, and we have big plans for the future! Check out our Instagram and Twitter accounts at

Before our 2026 field season begins, we wanted to re-introduce ourselves! The Potomac-Chesapeake Dolphin Project aims to inform conservation efforts and animal behavior research by studying the Tamanend’s bottlenose dolphins.

We had so much fun at ! This weekend we traveled to Wilmington, NC with the whole Mann Lab to present our myriad of research to the broader marine mammal community. We were honored to have three presentations at the conference. We are so proud of our two amazing undergraduates Shea O’Day (‘26) and Gracie Dogramaci (‘28) for presenting their undergraduate projects and research assistant Arielle Solomon for presenting her research regarding male-female-calf associations!

Happy National Dolphin Day!

We obviously love our dolphins and our work to study them. Studying the dolphins of the Potomac-Chesapeake is important to inform conservation efforts in our environment.

Guess what else we did this past weekend?

We went into the field to change the batteries on our FPod, a passive acoustic monitor that helps us measure dolphin presence and absence.

We are excited to see what data the 2026 field season brings us! Stay tuned in the next couple weeks when we will introduce our 2026 field team!

We had a great time meeting so many members of our community this past weekend at the Virginia Osprey Festival!

As a project, we enjoy spreading knowledge and love for the dolphins in our ecosystem. It was a special treat for our Associate Director Dr. Ann-Marie Jacoby to present on the importance of dolphins and our research!

And, we would like to extend a special thank you to everyone who contributed donations to the project. With your help, we are able to continue our work studying and informing conservation efforts regarding our dolphins.

Need some good news? Follow the pod! 🐬

One of the questions we're most often asked is whether dolphins really do live in the Potomac's waters. The answer: A resounding yes! For years, researchers at have devoted countless hours of observation and study into better understanding the movements of our local Tamanend's bottlenose dolphin population. Thanks to the dedication of these scientists, we now know that over 2,000 dolphins have been spotted in and around the river. Pretty amazing!

The key to unlocking the mysteries of the Potomac's dolphins? Plenty of camera time. The PCDP has collected tens of thousands of photos, giving critical insights into behaviors and health. Read about how machine learning has helped researchers decode the deeper meanings of identifying marks on dorsal fins at the link in the comments.
