Keppel Bay Geomorphology and Stratigraphy, South-east Queensland

Geomorphological and stratigraphic data for Keppel Bay, a shallow coastal embayment adjacent to the Fitzroy River in Queensland, Australia. The dataset, hosted by the Australian Ocean Data Network, describes seabed morphology, sub-bottom profiles, and sediment cores revealing the palaeo-Fitzroy River path and sediment distribution influenced by Late Quaternary sea-level changes. It was last updated on 2026-04-10.

Use Cases

• Model Late Quaternary sea-level change impacts on coastal morphology based on described seabed features.
• Analyze sediment distribution and infill patterns in palaeochannels based on core and profile data.
• Study tidal and wind-driven sediment transport processes based on described subaqueous dune formations.
• Reconstruct the Holocene retreat path of the Fitzroy River based on described relict channels and stratigraphy.

Strengths

• Data describes a complex coastal system influenced by multiple factors: Late Quaternary sea-level change, relict topography, diverse catchment, macrotidal processes, and flood events.
• Includes multiple data types: seabed morphology, sub-bottom profiles, and sediment cores.
• Specific geographic detail is provided, including the location under approximately 60 m of water and the progradation of the coast by several kilometres.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data formats are PDF and HTML, which may require extraction for computational analysis.
