Seabed Morphology and Geomorphology Maps for the Coral Sea Marine Park

Geoscience Australia's seabed maps for the Flinders Reefs and Cairns Seamount areas apply a two-step classification system. The maps integrate multibeam surveys, LiDAR, and bathymetry data at resolutions as high as 1 meter for key features. This product is intended for marine park managers, regulators, and the public.

Use Cases

• Marine spatial planning based on classified seabed morphology and geomorphology features.
• Habitat modeling and conservation assessment using high-resolution bathymetry and backscatter data.
• Geomorphic interpretation of seamounts and reefs by integrating seabed imagery and sediment samples.

Strengths

• Uses a nationally consistent two-part seabed geomorphology classification system.
• Derived from multibeam, LiDAR, and bathymetry data, with a subset gridded at 1-meter horizontal resolution.
• Supplemented by backscatter intensity, seabed imagery, and sediment samples for interpretation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
