Seabed Morphology and Geomorphology Maps of the Coral Sea Marine Park

Geospatial seabed morphology and geomorphology information for Flinders Reefs and Cairns Seamount within the Coral Sea Marine Park, north-eastern Australia. The data product was created by Geoscience Australia using a two-part classification system applied to bathymetry digital elevation models and supplementary datasets. The maps are intended for use by marine park managers, regulators, and the general public.

Use Cases

• Marine spatial planning based on seabed morphology and geomorphology classifications.
• Habitat mapping and conservation assessment based on interpreted geomorphic characterisations.
• Quantitative analysis of seabed geometries based on polygon extents of topographic highs, lows, and planar areas.
• Integrating bathymetry with backscatter and seabed imagery for geological interpretation.

Strengths

• Uses a nationally consistent two-part seabed geomorphology classification system.
• Derived from high-resolution data sources, including an 8 m DEM for Flinders Reefs and a 1 m grid subset for Cairns Seamount.
• Informed by supplementary datasets like backscatter intensity, seabed imagery, and sediment samples.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
