(CNN) -- A Chinese patrol ship looking for signs of Malaysia Airlines Flight 370 in the southern Indian Ocean discovered Saturday a pulse signal with a frequency of 37.5 kHz, state news agency Xinhua reported. "That is the standard beacon frequency" for both so-called black boxes -- the cockpit voice recorder and the flight data recorder, said Anish Patel, president of pinger manufacturer Dukane Seacom. "They're identical." But experts cautioned that no confirmation had been made that the signal was linked to the missing plane. "This could be a variety of things," said oceanographer Simon Boxall, who said the frequency is used by a variety of instruments. "We've had a lot of red herrings, hyperbole on this whole search," the lecturer in ocean and earth science at the University of Southampton told CNN. "I'd really like to see this data confirmed." He added, "It could be a false signal."
