Brief description

On behalf of Australia, and in support of the Malaysian accident investigation, the Australian Transport Safety Bureau (ATSB) led 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 marine surveys, which were undertaken to provide a detailed map of the sea floor topography and to aid navigation during the underwater search.

This dataset comprises Side Scan Sonar (SSS), Synthetic Aperture Sonar (SAS) and multibeam sonar backscatter data at 5 m resolution. Data was collected during Phase 2 marine surveys conducted by the Governments of Australia, Malaysia and the People’s Republic of China between September 2014 to January 2017. The data was acquired by Echo Surveyor 7 (Kongsberg AUV Hugin 1000), Edgetech 2400 Deep Tow and SLH PS-60 Synthetic Aperture Sonar Deep Tow deployed from the following vessels: Fugro Supporter, Fugro Equator, Fugro Discovery, Havila Harmony, Dong Hai Jiu 101 and Go Phoenix.

Lineage

The MH370 Phase 2 5 m resolution dataset provides an overview of the sonar data (Side Scan Sonar, Synthetic Aperture Sonar and multibeam sonar backscatter) acquired during the operational search. This product aims to be more accessible and user friendly to a non-scientific user than the supplied raw and processed data.

The dataset is split into four different layers (Fugro Deep Tow, Fugro Autonomous Underwater Vehicle, Go Phoenix and Dong Hai Jiu 101) according to the system used to acquire the data. There is considerable overlap between these different layers, and within the layers, which aims to show features from various perspectives.
