Australian Seabed Bathymetry Gridded At 50-Meter Resolution

Geoscience Australia's 50m Multibeam Dataset contains all multibeam bathymetry data held by the agency as of June 2018. It was compiled from data holdings within Australia's offshore area and international waters, gridded at a 50-meter resolution. The dataset is maintained by the Australian Ocean Data Network.

Use Cases

• Model seafloor terrain and slope using the 50-meter resolution bathymetry grid.
• Analyze spatial patterns in seabed depth for habitat mapping and geological studies.
• Integrate bathymetry holdings with other marine datasets using the associated vector product for source attribution.

Strengths

• Gridded at a consistent 50-meter spatial resolution.
• Compiles all multibeam bathymetry data held by Geoscience Australia as of a specific date (June 2018).

Limitations

• Data is static from a 2018 compilation, potentially missing newer surveys.
• Specific row count, total area coverage, and data volume metrics are unknown.
