The search for missing Malaysia Airlines Flight 370 has resumed in the southern Indian Ocean.
Three ships will participate in the operation - the GO Phoenix, commissioned by the Malaysian government, and the Equator and Discovery, which are provided by Dutch contractor Furgo.
Crews will use sonar, video cameras and jet-fuel sensors to search the seabed for the Boeing 777, seven months after the jet vanished during a flight from Kuala Lumpur to Beijing with 239 people on board.
The search was suspended for four months after operations from the air and on the sea, as well as an undersea probe, failed to locate any sign of the aircraft.
Experts analyzed satellite transmissions from the plane to pinpoint the best area to conduct the new search.
Crews have worked ever since to map the seabed of the new search zone, about 1,800 kilometers west of Australia.
Australia is spearheading the search, but Australian officials are "cautiously optimistic" the plane will be located in the refined search zone.
