Australian authorities have said that the missing Malaysia Airlines flight MH370 is not in the area of ocean where acoustic pings were detected and presumed to be coming from the aircraft.

Australia’s Joint Agency Co-ordination Centre (JACC) said in a statement that the Bluefin-21 autonomous underwater vehicle has completed its final mission searching the remaining areas within its depth operating limits.

"The search in the vicinity of the acoustic detections can be considered complete and the area can been ruled out as being the final resting place of MH370."

According to the Australian Transport Safety Bureau (ATSB), the search in the vicinity of the acoustic detections can be considered complete and the area can been ruled out as being the final resting place of MH370.

Following the development, search efforts will now focus on evaluating all existing information and analysis, conducting a bathymetric survey to map the sea floor and involving more specialist services.

The Chinese survey ship Zhu Kezhen has already started the bathymetric survey, or mapping, of the ocean floor of the areas provided by the ATSB. The survey is expected to take nearly three months.

Recently, Malaysia’s aviation authorities released the raw satellite data used to determine that the missing Malaysia Airlines flight MH370 crashed in the southern Indian Ocean, following pressure from the families of the 239 people on-board.

The 47-page flight data report included communication logs from British satellite telecommunications company Inmarsat, with explanations to help the public understand them.
