Fitzroy River Palaeochannel Bathymetry on the Great Barrier Reef

A prominent, unburied palaeochannel of the Fitzroy River has been discovered on the continental shelf of the southern Great Barrier Reef. The data, reported by the Australian Ocean Data Network, provides new evidence for sediment transport patterns during sea-level changes. The dataset was last updated in April 2026.

Use Cases

• Analyzing bathymetric expression to model sediment transport from the Fitzroy River to the continental slope.
• Comparing the unburied Fitzroy palaeochannel morphology with the buried Burdekin palaeochannel to understand shelf aggradation processes.
• Characterizing the transition zone between terrigenous and mixed siliciclastic-carbonate shelves using the southern Great Barrier Reef as a case study.

Strengths

• Focuses on a newly discovered and distinct geomorphic feature (the unburied Fitzroy River palaeochannel).
• Provides data relevant to a major sedimentary province (the world's largest tropical mixed siliciclastic-carbonate system).

Limitations

• Specific data volume (row count, file size) and granularity (e.g., resolution of bathymetric measurements) are unknown.
• The primary format is an HTML publication, which may require extraction to access structured geospatial data.
• Geographic coverage is limited to the specific region of the southern Great Barrier Reef shelf.
