Sediment and Water Movement at One Tree Reef, Great Barrier Reef, 1979

One Tree Reef in the southern Great Barrier Reef was monitored for water circulation and sediment flux in March/April 1979. The dataset, provided by Geoscience Australia Data, details flow patterns and sediment transport across windward and leeward reef margins, coral flats, and sand sheets. It explains sediment distribution in the lagoon based on observed energy patterns.

Use Cases

• Modeling sediment flux patterns based on described water flow reversals during spring and neap tides.
• Analyzing the relationship between water velocity and sediment transport across different reef zones like coral flats and sand sheets.
• Studying the net loss or gain of suspended sediment in a reef lagoon system based on the described tidal cycles.
• Mapping mud concentration distribution in a lagoon based on the described energy patterns and flushing events.

Strengths

• Focuses on a specific, well-defined geographic location: One Tree Reef in the southern Great Barrier Reef.
• Provides comparative analysis of sediment transport during both spring and neap tidal cycles.
• Describes monitoring of both water circulation and sediment flux, suggesting linked physical measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single monitoring period in 1979; temporal coverage is limited.
