MH370 Phase 1 150m Bathymetry datasets (GA-4421,GA-4422 & GA-4430)

Created 17/10/2025

Updated 17/10/2025

On behalf of Australia, the Australian Transport Safety Bureau (ATSB) is leading search operations for missing Malaysian airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate bathymetric surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Bathymetric data was acquired by multibeam sonar mounted on the hull of multiple vessels (GA survey reference: GA-4421, GA-4422 & GA-4430). Bathymetric surveys were conducted from June 2014 to February 2017, collecting over 710,000 square kilometres of data in the search area and along transit lines (to and from the search area). This dataset allows exploration of the seafloor topography of bathymetry data at a resolution of 150 m across the search and transit areas of the Southern Indian Ocean. The dataset is overlain on a hillshade created from the 150m resolution bathymetry data. The hillshade was created with the parameters of point illumination azimuth at 45 degrees and altitude of 45 degrees.This dataset is not to be used for navigational purposes.
