Scientists are utilizing drones and different expertise to review nice white sharks alongside the coast of Southern California to raised perceive interactions between these marine predators and folks and assess the dangers to human beachgoers.
The 2-year research by the Shark Lab at California State College deploys drones for aerial surveillance of the sharks and makes use of underwater robots, whereas the scientists additionally tag some sharks utilizing a spear that matches the animals with a transmitter to trace their actions.
“Drones have truly modified our world. They’ve turn into a way more highly effective, price efficient software. So prior to now we used helicopters and planes and it was very costly,” Shark Lab Director Chris Lowe advised Reuters.
Regardless of carnage depicted in movies like “Jaws” and “Sharknado,” shark assaults on persons are uncommon – people kill exponentially extra sharks than sharks kill people – however they are often lethal. The Maine Division of Marine Sources mentioned a 63-year-old New York Metropolis girl died on Monday after being attacked by an excellent white shark whereas swimming within the Atlantic.

“Even supposing shark populations are going up and extra persons are utilizing the water than ever earlier than, we’re probably not seeing extra individuals truly being bitten by sharks,” Lowe mentioned. “Actually, in some years, the speed has gone down. So what that tells us, as a scientist, is that we’re not on their menu in any respect. However often accidents occur.”
From Santa Barbara to San Diego, the Shark Lab researchers have been flying drones alongside the shoreline to rely the variety of sharks and folks and take a look at the proximity of the creatures to the shore and swimmers. The coastal group of Del Mar, north of San Diego, is house to an excellent white shark nursery, the researchers mentioned.
Lowe mentioned he hopes the analysis will assist lifeguards defend the general public by higher understanding how sharks behave and whether or not some species are extra aggressive than others.

Shark Lab researcher Patrick Rex mentioned the scientists are attempting to find out what environmental elements improve the chance of individuals encountering the sharks.
“We’re additionally making an attempt to determine this out for white sharks as properly, what environmental parameters deliver them nearer to shore and perhaps nearer to people,” Rex mentioned.
