Australian Seabed Bathymetry Gridded at 50-Meter Resolution

June 2018 compilation of all multibeam bathymetry data held by Geoscience Australia. The dataset covers the offshore area of Australia, including international waters, and is gridded at a 50-meter resolution. It is accessible via a web mapping service on Geoscience Australia's Marine data portal and is not intended for navigational purposes.

Use Cases

• Modeling seafloor terrain based on gridded bathymetry data.
• Analyzing seabed features and geological structures within Australia's offshore jurisdiction.
• Supporting marine spatial planning and environmental research based on high-resolution depth information.

Strengths

• Gridded at a consistent 50-meter resolution.
• Compiles all multibeam bathymetry holdings from Geoscience Australia as of a specific date (June 2018).
• Covers a defined geographic area including Australia's offshore zone and international waters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Freshness should be verified as the core data snapshot is from 2018.
