Geomorphology and Stratigraphy of Keppel Bay, South-east Queensland

Geomorphological and sediment distribution data for Keppel Bay, a shallow coastal embayment adjacent to the Fitzroy River in Queensland, Australia. The dataset, sourced from the Australian Ocean Data Network, describes a complex system influenced by Late Quaternary sea-level change, relict topography, and macrotidal processes. It includes findings from seabed morphology, sub-bottom profiles, and sediment cores, revealing the palaeo-path of the Fitzroy River and coastal progradation over the last few thousand years.

Use Cases

• Model paleo-river pathways and coastal evolution based on described seabed morphology and sub-bottom profiles.
• Analyze sediment transport and deposition patterns based on the described distribution of muddy sand and relict fluvial deposits.
• Study the impact of Late Quaternary sea-level change on coastal embayments based on the described geomorphological complexity.
• Map subaqueous dune fields and tidal current influences based on the described sediment transport in the outer bay.

Strengths

• Description details a complex system influenced by multiple factors: Late Quaternary sea-level change, relict topography, macrotidal processes, and flood events.
• Data reveals specific paleogeographic features, such as the former path of the Fitzroy River to a position now under approximately 60 m of water.

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.
