The French nuclear submarine Emeraude today joined the search off the coast of Brazil for Air France flight 447's flight recorders, which may help investigators understand why the Airbus A330 went down on May 31 with 228 people on board. A research vessel from the French Research Institute for Exploitation of the Sea is expected to arrive Friday carrying the Nautile mini-submarine and a remote-controlled robot called Victor 6000 to help locate the black boxes before they stop emitting locating signals, ABC News reports.
The Emeraude is expected to trawl 13 square miles (35 square kilometers) daily, using sonar to try to pick up the boxes' acoustic beacons, whose signals are expected to start fading 30 days after the crash, the Associated Press reports. The submarine will be reinforced by two U.S. underwater audio devices capable of picking up signals even at a depth of 20,000 feet (6,100 meters), according to the Associated Press.
