Geomorphology and Stratigraphy of Keppel Bay, Queensland, Australia

The dataset describes the complex seabed morphology and sediment distribution of Keppel Bay, a large shallow coastal embayment in Queensland, influenced by Late Quaternary sea-level changes and the Fitzroy River. It was published by the Australian Ocean Data Network and last updated on 2026-04-28. The data reveals the former path of the Fitzroy River across the continental shelf and the infilling of palaeochannels during the Holocene.

Use Cases

• Modeling Late Quaternary sea-level change impacts on coastal geomorphology based on described seabed morphology and sub-bottom profiles.
• Analyzing sediment transport and deposition patterns in macrotidal environments based on described subaqueous dunes and sediment composition.
• Reconstructing palaeo-river pathways and continental shelf evolution based on described relict channels and fluvial deposits.

Strengths

• Focuses on a specific, complex coastal system (Keppel Bay) with detailed geological and hydrodynamic influences described.
• Includes multiple data types suggested by the description, such as seabed morphology, sub-bottom profiles, and sediment cores.
• Last updated date is provided (2026-04-28 15:22:46.865446).

Limitations

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