Lagoon Sedimentation and Circulation Observations at One Tree Reef, Great Barrier Reef

Observations of water movement and sediment transport at One Tree Reef under modal wind, wave, and tide conditions. The dataset, published by the Australian Ocean Data Network, examines lagoon currents, bioturbation effects, and the role of low-frequency, high-energy events in sediment sorting and transport. Findings are applicable to other reefs with well-developed lagoons in the southern Great Barrier Reef.

Use Cases

• Modeling lagoon sediment transport based on observations of water movement under modal conditions.
• Analyzing the impact of bioturbation on sediment suspension based on descriptions of grain size and current velocity interactions.
• Studying the role of patch reefs in local sediment supply based on descriptions of sediment size increases and leeward extensions.
• Assessing sediment sorting during high-energy events based on descriptions of southeast to northwest water movement.

Strengths

• Observations are directly applicable to other reefs with well-developed lagoons in the southern Great Barrier Reef.
• Analysis includes multiple factors: modal wind, wave, tide conditions, bioturbation, and high-energy events.

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 on a specific reef.
