Sevengill Shark Tracking in San Diego

To identify sharks which return from year to year.
Analyze photos taken using a pattern recognition algorithm

A citizen science project which allows local divers photo document encounters with Sevengill sharks (Notorynchus cepedianus). The Sevengill Shark Sightings is a portal through which data is entered into the 'Wildbook' pattern recognition algorithm program.

Two pattern recognition algorithms are used to analyze the freckling patterns of each shark to determine which animals are returning each year.
