Marine Bathymetry Data Collection from Australian Waters

Australian Ocean Data Network provides a collection of bathymetric data for mapping the sea floor. The dataset integrates singlebeam, multibeam, satellite altimetry, and airborne laser (LADS) measurements acquired by Geoscience Australia and other agencies. It was last updated on 2026-06-04.

Use Cases

• Generate low-resolution seafloor maps over large areas based on satellite altimetry data.
• Create high-resolution bathymetric models for specific regions based on multibeam echosounder or LADS data.
• Analyze seafloor patterns and features along vessel tracks based on singlebeam echosounder data.

Strengths

• Integrates data from multiple collection methods, including satellite, singlebeam, multibeam, and LADS.
• Multibeam and LADS data are described as having very high resolution, with accuracy better than one metre.
• Sourced from Geoscience Australia and other government and non-government agencies.

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 or source bias inherent to data_gov_au.
