Meanwhile the submersible sent down to scan for traces of a missing Malaysia Airlines plane moved to an adjacent area after trawling the initial plot and finding nothing, searchers said Sunday.
The Bluefin-21 underwater drone has completed a sonar scan of a circular zone 20 kilometres across.
The midpoint in the zone was triangulated from the last a coustic ping that could have come from the emergency beacon aboard MH370. It is 1,584 kilometres north-west of Perth.
The Boeing 777 vanished an hour into a night flight March 8 from Kuala Lumpur to Beijing with 239 people on board, mostly Chinese nationals.
The last ping was detected April 8. The Joint Agency Coordination Centre said from its Perth headquartersthat bad weather had prompted the suspension of an air and surface search for floating debris.
