Australian Marine Geospatial Data Including MH370 Search Bathymetry

Geoscience Australia's marine geospatial web service contains bathymetry, backscatter, and marine sediment data. It includes 150 m and optimal resolution bathymetry, 5 m sidescan sonar, and synthetic aperture sonar data from the multinational search for Malaysian Airlines Flight MH370 in the Indian Ocean. The service allows exploration of seafloor topography compiled from multibeam sonar and other marine datasets.

Use Cases

• Model seafloor topography based on compiled multibeam sonar bathymetry data.
• Analyze marine sediment distribution based on the derived sediment data layers.
• Plan marine survey missions based on bathymetry collection priority and planning areas.
• Study high-resolution seafloor features based on 5 m sidescan sonar and synthetic aperture sonar data from the MH370 search.

Strengths

• Includes data from a major multinational search operation (MH370) involving the governments of Australia, Malaysia, and China.
• Contains multiple data types: bathymetry, backscatter, sediment data, and derived layers.
• Provides specific resolution details for some data (150 m bathymetry, 5 m sidescan sonar).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey areas, primarily the Indian Ocean.
