Marine Geospatial Data Including Bathymetry and MH370 Search Sonar

Geoscience Australia's web service compiles multibeam sonar and other marine datasets for seafloor exploration. It includes bathymetry, backscatter, marine sediment data, and derived products. The data also contains specific 150 m and optimal resolution bathymetry, plus 5 m sidescan and synthetic aperture sonar data collected during the multinational search for Malaysian Airlines Flight MH370 in the Indian Ocean.

Use Cases

• Map seafloor topography based on compiled multibeam sonar data.
• Analyze marine sediment distribution based on the included sediment data layers.
• Study bathymetric coverage and collection priorities for survey planning.
• Examine high-resolution sonar data from the MH370 search area in the Indian Ocean.

Strengths

• Contains specific data from the MH370 search, including 150 m and optimal resolution bathymetry and 5 m sidescan sonar.
• Compiles multibeam sonar and other marine datasets from a national geoscience authority.
• Includes derived layers such as bathymetry coverage information and planning areas.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on Australian marine regions and specific survey areas.
