"We can monitor it from a drone or from any kind of air surveillance and we can see the animals and they really pay very little if any attention to water users. What happened to Phil is an unusual event and certainly for it to happen at this time of year when we would normally expect animals to not be present in these beach locations," Anderson said. Anderson says at the moment, they’re seeing a population resurgence of white sharks in Southern California. Shark Lab is working hand-in-hand with lifeguards across the coast, including Coronado, to better equip lifeguards with information to help address public safety concerns when it comes to shark sightings. One of the ways they’re doing it is through tagging sharks.
