Two bottlenose dolphins in the Potomac River, surfacing in almost perfect synchrony. Circles represent individual dolphins with the colored circles representing the two individuals (blue, red) for which networks were constructed. The PCDP aims to better understand and protect the bottlenose dolphins of the Potomac River and Chesapeake Bay. Conservation Through Research and Education The Potomac-Chesapeake Dolphin Project's (PCDP) mission is to better understand and protect the bottlenose dolphins (Tursiops truncatus) of the Potomac River and Chesapeake Bay. Phoca vitulina. 4A & 4C). 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. “We see quite a few more dolphins than we do in Shark Bay, let’s say, for an hour’s worth of research,” said Patterson at NOAA. View my sightings. One way to help determine which population the PC dolphins belong to is through what is called Photo ID. Figure 4. Coastal bottlenose dolphins populations (stocks) according to the National Marine Fisheries Service (NMFS). Dr. Helen Bailey and her team at the Chesapeake Biological Laboratory, University of Maryland Center for Environmental Science think dolphin numbers are up in the bay, but they want to be scientific about it. “We know very little about them,” says UMCES DolphinWatch.

The White House has a new occupant, but there are still dolphins in the Chesapeake Bay and the Potomac River. 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. With the dolphins identified, scientists can determine where the dolphins are coming from and going to. Using high quality photographs of individual dolphin dorsal fins (see a sample of our catalog here) we can match our PC dolphins to photographs in the Mid-Atlantic Bottlenose Dolphin Catalog. Scientists say dolphins used to visit the bay more frequently. The Potomac-Chesapeake Dolphin Project contributes and compares data and images of dorsal fins with other scientists up and down the Atlantic Seaboard through a central database of dorsal fin images (OBIS-SEAMAP). It is illegal to approach or harass wild dolphins, though they are curious creatures that will approach boats and humans, often While these seems like fairly straightforward questions, for migratory animals, coming up with the answers is quite difficult. It is thought that during such events dolphins may exchange infectious respiratory droplets.
