Keppel Bay Geomorphology and Stratigraphy, South-east Queensland

Keppel Bay, a shallow coastal embayment adjacent to the Fitzroy River in Queensland, Australia. The dataset, from the Australian Ocean Data Network, describes the complex seabed morphology and sediment distribution shaped by Late Quaternary sea-level changes, tidal processes, and flood events. It reveals the palaeo-path of the Fitzroy River across the continental shelf and infilling patterns over the last few thousand years.

Use Cases

• Modeling paleo-drainage systems based on described relict channels and the former path of the Fitzroy River.
• Analyzing sediment infill patterns and coastal progradation rates based on described Holocene depositional history.
• Mapping seabed geomorphology and sediment types based on described features like subaqueous dunes and relict fluvial deposits.

Strengths

• Describes a specific, complex coastal system influenced by multiple factors including macrotidal processes and Late Quaternary sea-level change.
• Includes findings on the paleo-Fitzroy River path, now under approximately 60 m of water, providing a concrete historical reference.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on Keppel Bay.
