Australian Coastal Sediment-Water Interaction Data for Nutrient Cycling Studies

Australian coastal data on sedimentary processes, including carbon, nitrogen, phosphorus, iron, and silicon diagenesis at the sediment-water interface. The dataset, from Geoscience Australia Data, includes a review of limited existing data and results from benthic chamber studies, such as those from Port Phillip Bay. It was last updated on 2026-04-30.

Use Cases

• Modeling nutrient (N, P, Si) speciation and fluxes to the water column based on benthic chamber measurements.
• Investigating the role of iron as an intermediary in nitrification/denitrification and its control on phosphorus fluxes.
• Analyzing organic matter sources and early diagenesis using TOC, TOC:TN, and TOC:TP ratios in sediments.
• Evaluating the impact of benthic processes, including bioirrigation and diffusion, on coastal water quality.

Strengths

• Includes specific measurements of Total Organic Carbon (TOC) in Australian sediments, ranging from <1% to 15% weight.
• Describes results from benthic chamber studies, which provide direct measurements of sediment-water exchange.
• Covers multiple key biogeochemical elements and processes: C, N, P, Fe, and Si diagenesis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
