“We have an acoustic event. The job now is to determine the significance of that event. It does not confirm or deny the presence of the aircraft locator on the bottom of the ocean,” Houston said, referring to each of the three transmissions.
China's official Xinhua News Agency reported Saturday that the patrol vessel Haixun 01 on Friday detected a “pulse signal” at 37.5 kilohertz (cycles per second) -- the same frequency emitted by flight data recorders aboard the missing plane—in the southern Indian Ocean.
Houston confirmed the report, and said the Haixun 01 detected a signal again on Saturday within 2 kilometers (1.4 miles) of the original signal, for 90 seconds. He said China also reported seeing white objects floating in the sea in the area.
The British navy ship HMS Echo, which is fitted with sophisticated sound-locating equipment, is moving to the area where the signals were picked up and will be there in the next day or two, Houston said.
The Australian navy's Ocean Shield, which is carrying high-tech sound detectors from the U.S. Navy, will also head there, but will first investigate the sound it picked up in its current region, about 300 nautical miles (555 kilometers) away, he said.
Australian air force assets are also being deployed into the Haixun 01's area to try to confirm or discount the signals' relevance to the search, Houston said.
In Kuala Lumpur, families of passengers aboard the missing plane attended a prayer service on Sunday that also drew thousands of Malaysian sympathizers.
