Geographe Marine Park Seafloor Bathymetry at 5-Meter Resolution

Geoscience Australia contributed bathymetric data for the management of Australia's national marine park network, which covers 3.3 million square kilometers. The dataset includes a 5-meter resolution bathymetry grid and derived morphological surface classifications for the Geographe Marine Park. It was released as part of a National Environmental Science Program project and is not for navigational use.

Use Cases

• Seafloor habitat modeling based on bathymetric slope and morphological surface classifications.
• Marine park management planning based on high-resolution bathymetry and derived hillshade products.
• Geomorphological analysis of the seafloor based on the two-part classification scheme (Plain, Slope, Escarpment).

Strengths

• High-resolution 5-meter bathymetry grid derived from vessel sonar systems.
• Includes derived morphological surface classifications based on a published scientific scheme.
• Data supports the management of a 3.3 million square kilometer marine park network.

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.
