Understanding why dolphins visit the Chesapeake Bay

Report your dolphin sightings 

Join 14,600 DolphinWatchers in and around Chesapeake Bay by signing up and logging into the app via iPhoneAndroid, or the ChesapeakeDolphinWatch website. View the locations of recent and past dolphin sightings on a map, as well as images DolphinWatchers have submitted. By tracking the occurrence of dolphins and their movements, we’ll gain a better understanding of how bottlenose dolphins use the Bay and how to protect them in our local waters.

Fifth anniversary Chesapeake DolphinWatch book

As a thank you to DolphinWatchers and a celebration of what we have learned about dolphins in the Chesapeake Bay from sighting reports, we created a Chesapeake DolphinWatch - Dolphins of the Chesapeake Bay photo book. We do not receive any commission from the sale of the book, but all donations go towards our dolphin research and providing copies of the book to schools and public libraries around the Chesapeake Bay.
