Sediment and Water Flux at Boulder Reef Before, During, and After Cyclone Dominic

Monitoring data from Boulder Reef in the Northern Great Barrier Reef captures sediment and water flux before, during, and after Tropical Cyclone Dominic. The dataset likely contains measurements of water velocity, sediment load composition (including particulate organic and inorganic carbon), and terrestrial clay inputs. It is provided by Geoscience Australia Data and was last updated on 2026-05-14.

Use Cases

• Modeling sediment transport dynamics based on water velocity and sediment load data.
• Analyzing the impact of cyclonic rainfall and river discharge on reef sedimentation.
• Studying the ratio of reef-derived to terrigenous sediment components over time.
• Investigating long-term clay deposition cycles in Holocene reef sections.

Strengths

• Captures a high-energy event with specific measurements: water velocities up to 60 cm/s and sediment loads 2-5 times greater during the cyclone.
• Provides quantified terrestrial inputs: clay deposition estimated at 135-228 tonnes every five years over a potential 5000-year period.
• Includes temporal context with monitoring before, during, and after the cyclone, including a noted secondary sediment pulse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is available only in PDF and HTML formats, which may complicate machine-readability.
