Shark Watch

Shark Watch is a citizen science shark education and conservation program.

Reaching youth directly and teaching them about the sharks of the Bay and marine ecosystems, Shark Watch takes science to the field observing and collecting data using the iNaturalist App. Through a grant from the California Coastal Conservancy, we are taking under-served youth to the Bay and on the Bay introducing them to sharks, rays and Bay ecosystems. Contact us to participate in San Francisco Bay Shark Watch Education the program. Youth and citizens are recording observations of sharks and rays in the wild and recording the data using the iNaturalist App.  This Citizen Science provided data will help us understand the range, movements, distribution and behavior of San Francisco Bay, Tomales Bay and Pacific sharks, skates and rays.

Divers getting into the act. 

We are now partnering with the Ocean Sanctuaries Project and the dive community in San Diego logging sevengill shark sightings and sharks of San Diego using the National Geographic’s Fieldscope.

Ocean Sanctuaries Project

We are combining our image data set with the Ocean Sanctuaries Project, a collection of divers who are documenting sharks in the La Jolla Cove. Several species of sharks aggregate in the cove including Leopard (Triakis semifasciata) Soupfin (Galeorhinus galeus) and Sevengill shark (Notorhynchus cepediana) among others.
