Photo-Identification
Photo- Identification
Photo-identification is a non-invasive research method used to identify individual dolphins base on unique markings on their dorsal fins, such as nicks, notches, and scars. These features allow researchers to track individual dolphins over time.
By documenting sightings and matching individuals across surveys, researchers can better understand population size, site fidelity, movement patterns, and social structure.
Research & Protection
Our photo-identification research is conducted in accordance with the Marine Mammal Protection Act (MMPA), ensuring that dolphins are observed safely and without disruption. This allows us to study individuals in their natural environment while supporting long-term conservation efforts.
Data & Collaboration
All viable photos and data are shared with Duke University and included in two databases:
- MABDC (Mid-Atlantic Bottlenose Dolphin Catalog)
- OBIS-SEAMAP (Ocean Biogeographic Information System – Spatial Ecological Analysis of Megavertebrate Populations)
These databases support research beyond our local study area, helping scientists better understand dolphin populations and their movement patterns along the East Coast and in other regions.
