Seabed mapping technology to find missing aircraft

The Commonwealth Scientific and Industrial Research Organization (CSIRO) has released a detailed map of the seafloor in the southern Indian Ocean to find the Malaysian aircraft.

David Griffin, CSIRO scientist, said satellites from the United States and Europe continually monitored the ocean to measure sea level, the BBC reported.

"We use thermal imagery to study the direction of ocean currents ," he said.

According to Griffin, if the search teams detect the MH370 debris, it is easier to locate the jet plane than the ocean currents. However, multi-dimensional underground flows make it difficult for vehicles to detect missing pieces of the missing Boeing 777 aircraft.

Simon Boxall, a British oceanographer, said the signals could help international forces narrow their search.

"If a debris is exposed, the scope of the search will fall from 85,000 square miles to 10 square miles ," Baxall explains.

The team also plans to drop the Sono float to locate the black box. They want to float into the 250km ² sea area and near the location where Chinese vessels detect the sound signal. However, Gerry Soejatman, an aviation analyst independence, said the process of mapping the area seabed has an area of one km ² square detectors sonar must take place in a month or more.

The most advanced seafaring device of the search teams is the Bluefin-21 diving robot. However, it only works at a maximum depth of 4.500m. If debris is located in deeper areas, they will have to use the Remus and Remora mini-dive submarines, which have been involved in the search for French Air France's black box.
