That effort grew into the Potomac-Chesapeake Dolphin Project, which today surveys the social and super-smart mammals from May through October in about 14 square miles of the Potomac. Using network modeling techniques, we plan to investigate both transmission mechanism and compare simulated outbreaks to actual stranding data in order to elucidate the most likely mechanism of transmission. This tracker includes the ability to view the locations of recent and past dolphin sightings on a map and provides information about dolphins and the Chesapeake Bay.
