All this may help investigators find traces of MH370. It might even yield more clues about exactly what happened to the stricken aircraft after radio contact was lost shortly after take-off.
A lot depends on the contour mapping. This will allow the towfish to be operated safely in a part of the ocean that had remained largely unexplored. The mapping was carried out by Zhu Kezhen, a Chinese naval ship, and Fugro Equator, a specialist vessel contracted from Fugro, a surveying company based in the Netherlands. The ships are fitted with hull-mounted multi-beam sonar systems. Sonar has long been used to measure the depth of the ocean by transmitting acoustic pulses and listening for the delay in their echoes from the sea floor. The multi-beam systems used by the survey ships allow much wider areas of the ocean floor to be covered in less time.
