A new phase of the search for missing Malaysia Airlines flight MH370 began on Monday as the first of two ships began scouring the Indian Ocean.
The plane vanished from radar in March shortly after take-off and is believed to have crashed in the southern Indian Ocean, killing all 239 people on board.
After an exhaustive aerial survey, the search for the missing plane had a fourth-month hiatus while experts mapped the part of the ocean where the plane is believed to have crashed.
On Monday the GO Phoenix arrived in the new search area and began an underwater search. The Fugro Discovery is expected to arrive in the search area in mid-October. The ships will use sonar technology close to the sea floor to scour the Indian Ocean for signs of the missing plane, and will send submersible devices.
The joint agency coordination centre responsible for the search said new analysis undertaken had refined the scope of the search.
“Recent refinement to the analysis has given greater certainty about when the aircraft turned south into the Indian Ocean and has produced a better understanding of the parameters within which the satellite ground station was operating during the last flight of MH370,” it said in a statement.
The search has moved to a primarily underwater operation, which will involve searching previously uncharted depths of the Indian Ocean.
The mission is being undertaken by the Australian and Malaysian governments, which are sharing the costs of the renewed search.
