Dry-Season Water and Sediment Chemistry of Keppel Bay

Two dry-season surveys document biogeochemical properties of the water column and underlying sediments in the Fitzroy Estuary and Casuarina Creek. The data supports research into sediment, nutrient, and agrochemical pathways in macrotidal estuaries facing ecological change from agricultural activities. The Australian Ocean Data Network published this report, with a platform record last updated in April 2026.

Use Cases

• Analyze sediment accumulation rates using core incubation and bottom sediment property data.
• Model nutrient pathways from catchment to reef using water column observation and biogeochemistry data.
• Assess links between primary production and sediment dynamics using the preliminary zonation data for Keppel Bay.
• Study the impact of land-use changes by comparing sediment properties across the defined sampling strategy locations.

Strengths

• Data originates from two dedicated dry-season field surveys designed to address specific research questions.
• Report provides integrated analysis of water column, sediment properties, and core incubations for a holistic view.

Limitations

• Dataset scope is limited to two survey periods, lacking long-term temporal coverage.
• Sample size and row count are unknown, limiting statistical power for some analyses.
• Data is presented within report formats (HTML, PDF), requiring extraction for computational use.
