Hundreds of radio-tagged sharks tweet warnings at Australian swimmers
Automated system reaches farther, updates faster than radio or newspaper alerts.
Western Australia's beachgoers are a bit more informed as to the
whereabouts of the region's shark population this summer, thanks to a scientific initiative
that has fitted transmitters to more than 300 sharks of various types.
The transmitters are picked up by underwater receivers, and when a
tagged shark comes within a kilometer of the shore, a tweet appears in
the Surf Life Saving Western Australia twitter feed (@SLSWA).
The tweet notes the type of shark, the receiver that picked up the shark, and the time and date the shark was detected. By glancing at the feed, Australians can get an idea of the amount of shark activity (if any) at their beach of choice and decide whether or not to brave the waters.
Posting automated alerts via Twitter actually gets the information out to the public far more quickly than publishing hours- or days-old information in local newspapers or on the radio. "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," said SLSWA representative Chris Peck, speaking to Sky News.
The transmitters are being attached to sharks as part of an ongoing government program by the Western Australian Department of Fisheries to better understand the movement patterns of sharks, particularly great whites, around Western Australia. The tags are also intended to enhance public safety by alerting the public when sharks approach beaches. The tags should last up to a decade on their internal batteries.
