Broad Sound Sedimentology and Holocene History, Queensland

The Broad Sound dataset from the Australian Ocean Data Network describes sedimentology and Holocene history of a tropical estuary in Queensland. It likely contains geospatial data on sediment types, grain size parameters, and environmental groups derived from drilling and radiocarbon dating. The dataset was last updated on 2026-05-05.

Use Cases

• Modeling shoreline progradation based on the described 'fining upward' regressive sequence.
• Analyzing sediment transport patterns based on described seaward movement of terrigenous sediment and landward movement of calcareous sediment.
• Classifying environmental sediment groups based on described grain size parameters.
• Studying late Holocene sea-level stabilization based on evidence suggesting stabilization around 6000 years ago.

Strengths

• Provides a regressive model for environmental interpretation in ancient sediments, as stated in the description.
• Includes evidence from drilling and radiocarbon dating showing most sediments are of late Holocene age.
• Describes specific environmental zones (mangrove swamp, channel, supratidal flat) and their sediment characteristics.

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 Broad Sound, Queensland.
