This dataset presents reports of bottlenose dolphin sightings submitted to the Chesapeake DolphinWatch program by citizen scientists over the span of five years (2017-2022). This dataset includes all sighting reports submitted to Chesapeake DolphinWatch, whether or not they were confirmed to be true by trained researchers. Each sighting's confirmation status is listed in the "Status" variable. Please note that this data describes the presence of bottlenose dolphins as described by citizen scientists. A lack of sightings at a particular date and time does not necessarily indicate the absence of dolphins.
