'We're seeing more than ever': white shark populations rise off California coast

CSU Long Beach shark lab has tagged a record amount of white sharks, signaling a healthy ecosystem - and warmer waters

Chris Lowe is no longer surprised when he sees drone footage of juvenile white sharks cruising near surfers and swimmers in southern California's ocean waters.

Lowe directs the shark lab at California State University, Long Beach, and for the past 12 years he's been monitoring populations of juvenile white sharks off the southern California coast with tags, drones and planes. This year, Lowe has already tagged a record 38 sharks, triple the number that were tagged last year. Normally they'd be leaving by now, but instead we are seeing more sharks than ever."
