Packing for a trip to the beach in Western Australia? Be sure to include your smartphone, and don't forget to check
Scientists have found a way, essentially, to have sharks let you know when they're close to the beach. They've tagged 338 sharks with acoustic transmitters that trigger a computer alert when a shark comes within about a mile of a beach. The computer then generates a tweet on the Twitter account of Surf Life Saving in Western Australia (@SLSWA).
The tweets tell beachgoers what area the shark is in, how far away it is and its type and size. The shark monitoring is also valuable to researchers seeking to learn more about their movements.
The Twitter alert system aimed at beachgoers is quicker than traditional warnings that go out on the radio and in newspapers, Chris Peck, operations/community safety manager at SLSWA, told Sky News.

"You might not have got some of that information until the following day in which case the hazard has long gone and the information might not be relevant," Peck said.
But the tweets alone won't necessarily keep you safe. Western Australia's Department of Fisheries, which is partnering with SLSWA in the effort, said in a statement on its website that the public should still report sightings.
