Keppel Bay Sediment Transport Dynamics and Seabed Morphology

A sedimentological analysis of Keppel Bay, a macrotidal embayment linking the Fitzroy River to the Great Barrier Reef shelf. The dataset, from Geoscience Australia Data, includes seabed samples, shear-stress modelling, and three-dimensional acoustic imaging results. It characterizes sediment transport pathways, tidal sand ridges, and subaqueous dunes in this mixed wave- and tide-dominated system.

Use Cases

• Modeling sediment transport pathways based on described shear-stress modelling and acoustic imaging.
• Analyzing the morphology of subtidal sand ridges and dunes based on the three-dimensional acoustic imaging data.
• Studying the interaction of wave- and tide-dominated hydrodynamic regimes on sediment distribution.
• Assessing potential impacts of river sediment loads on coral reef ecosystems based on the described transport pathways.

Strengths

• Analysis integrates multiple data sources: seabed samples, shear-stress modelling, and three-dimensional acoustic imaging.
• Provides a detailed physiographic example of the seaward portion of a tide-dominated estuarine system.
• Characterizes a specific, complex environment (Keppel Bay) with implications for the Southern Great Barrier Reef shelf.

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 the single-site study of Keppel Bay.
