Holocene Terrigenous Sedimentation Model for the Central Great Barrier Reef Lagoon

Geoscience Australia Data provides a model of terrigenous sedimentation in the central Great Barrier Reef lagoon, focusing on the Burdekin Region. The data describes coastal progradation rates, which decrease from 2.5 m yr⁻¹ at the present delta front to 0.1 m yr⁻¹ north of Townsville. It characterizes four distinct sedimentary assemblages and discusses the pattern of late Quaternary sea-level oscillations.

Use Cases

• Modeling sediment dispersal patterns based on the Burdekin River as a point source.
• Analyzing coastal progradation rates and their spatial variation across the region.
• Studying the seismic stratigraphic elements of a prograding coastal wedge as described in the model.
• Investigating the distribution of relict and palimpsest sediments on the inner and middle shelf.

Strengths

• Provides specific quantitative sedimentation rates, such as 2.5 m yr⁻¹ progradation.
• Describes four distinct sedimentary assemblages (e.g., beach-ridge plain, chenier plain).
• Model is spatially focused on a well-defined region (central Great Barrier Reef lagoon, Burdekin Region).

Limitations

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