An underwater drone is continuing its Indian Ocean seabed search for the Malaysia Airlines plane wreck.
Eleven military planes and 12 ships were searching for flight MH370 on Saturday across 50,200 square kilometres.
Overnight the Bluefin-21 drone went on its sixth underwater mission and authorities are analysing the data.
The Australian Maritime Safety Authority said no objects of interest had been found so far.
The underwater drone has now embarked on its seventh mission.
Meanwhile, Malaysia and Australia are set to sign a deal on who handles the plane wreckage and black box flight recorders, international media reports say.
