Geoscience Australia Marine Data: Bathymetry and Sonar Surveys for MH370 Search

Geoscience Australia's web service contains marine geospatial data including bathymetry, backscatter, and marine sediment layers. The data includes 150 m and optimal resolution bathymetry, 5 m sidescan sonar, and synthetic aperture sonar data collected during phases 1 and 2 of the search for Malaysian Airlines Flight MH370 in the Indian Ocean. This service allows exploration of seafloor topography compiled from multibeam sonar and other marine datasets.

Use Cases

• Modeling seafloor topography based on compiled multibeam sonar and bathymetry data.
• Analyzing marine sediment distribution based on the described sediment data layers.
• Planning marine survey missions based on bathymetry collection priority and planning areas.
• Studying backscatter characteristics for seafloor classification based on the gridded backscatter data.

Strengths

• Includes data from a specific, high-profile international search operation (MH370).
• Contains multiple data products such as bathymetry, backscatter, and derived layers.
• Data is served via a Web Feature Service (WFS) for direct geospatial exploration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
