Thank you for reporting your dolphin sightings!
We were amazed by how many sightings we had in our first year.
Over 900 sightings were reported because our tracker—Chesapeake Dolphin Watch—was launched in late June 2017. Bottlenose dolphins occurred throughout the Bay, including in many rivers and creeks. Sightings peaked in June to August and then became more southerly during the autumn.
Thank you for supporting our research!
The number of users of our Chesapeake DolphinWatch app has increased and we have had higher sighting numbers this year with 388 reported in July 2018. We are now analyzing the group sizes and distribution of sightings across the Bay.
