California Beaches Are Using AI to Protect Swimmers From Sharks

By: Sam Watanuki | Published: Jul 29, 2024

Padaro Beach in California is a hub of activity, but most visitors are unaware of the technology working silently to keep them safe.

This beach, in particular, became a hotspot for juvenile great white sharks a few years ago, prompting innovative safety measures.

SharkEye Initiative Launches

In response to the shark sightings, the SharkEye initiative was launched by the University of California Santa Barbara’s Benioff Ocean Science Laboratory (BOSL).

The program uses drones to monitor the waters, ensuring the safety of beachgoers. SharkEye sends alerts to about 80 people, including local lifeguards and surf shop owners.

How SharkEye Works

SharkEye operates by flying drones over the water to capture footage of shark activity. If a shark is spotted, an alert is sent out.

The initiative aims to balance safety with education, helping the community understand more about these fascinating creatures.

AI Enhances Detection

SharkEye’s technology includes an AI system that analyzes video footage to detect sharks.

Neil Nathan from BOSL highlights the potential of this AI, stating, “Automating shark detection can be really helpful for a lot of communities outside of ours here in California.” The AI often spots sharks missed by human observers.

Human vs. AI Shark Detection

The rise of drone technology has changed how sharks are monitored. Traditional methods rely on human pilots who must differentiate sharks from other objects, a challenging task.

SharkEye’s AI, however, performs incredibly well, enhancing accuracy and reducing human error.

Monitoring the Coastline

For about five years, SharkEye has been running regular drone flights over Padaro Beach.
