DolphinWatch

Dolphin sightings in the Bay

Every sighting counts!

 

We were amazed by how many sightings we had in our first 2 years of this research.

Over 2,000 sightings were reported because since Chesapeake Dolphin Watch was launched in late June 2017. Bottlenose dolphins occurred throughout the Bay, including in many rivers and creeks. In both 2017 and 2018, total reported sightings peaked in the month of July.

Thank you for supporting our research!

 

Chesapeake DolphinWatch keeps growing. The number of new user registrations climbed steadily with a total of 1,811 users by the end of 2017 and 3,791 users by the end of 2018. 

We found dolphins in most of Chesapeake Bay!

 

In 2017 and 2018 dolphin sightings were seasonally stratified in Chesapeake Bay, meaning that we saw dolphins in different portions of the bay in different months. Dolphins were reported in the Lower Bay nearly year-round--including in the Rappahannock, Piankatank, York, Poquoson, James, Nansemond, Elizabeth, and Lynnhaven Rivers.

Middle Bay sightings were centralized in the warm months from May to September--including Patuxent, Potomac, Choptank, and Wye Rivers as well as Eastern Bay.

Upper Bay sightings were primarily in June and July--including Chester and Patapsco Rivers. We were surprised to see sightings as far north as Baltimore and a large number of sightings in the Chester River and main stem, north of the Bay Bridge.
