Marine Geospatial Data for Seafloor Exploration, Including MH370 Search Areas

Geoscience Australia's marine data web service compiles multibeam sonar and other datasets for seafloor exploration. It includes bathymetry, backscatter, marine sediment data, and specific data from the multinational search for Malaysian Airlines Flight MH370 in the Indian Ocean. The service is provided by the Australian Ocean Data Network and was last updated on June 23, 2026.

Use Cases

• Map seafloor topography based on compiled multibeam sonar and bathymetry data.
• Analyze marine sediment distribution based on the included sediment data layers.
• Plan marine survey missions based on bathymetry collection priority and planning areas.
• Study backscatter characteristics for seabed classification based on the gridded backscatter data.

Strengths

• Includes specific high-resolution data (5 m sidescan sonar, synthetic aperture sonar) collected during the MH370 search.
• Compiles data from multiple sources, including the Governments of Australia, Malaysia, and the People's Republic of China.
• Last updated on June 23, 2026, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
