Keppel Bay and Casuarina Creek Water and Sediment Biogeochemistry Survey

Two dry-season surveys of Keppel Bay and Casuarina Creek collected data on biogeochemical properties of the water column and underlying sediments. The dataset was published by Geoscience Australia Data and was last updated in March 2026. It was created to understand sediment, nutrient, and agrochemical pathways in macrotidal estuaries facing ecological change from agricultural activities.

Use Cases

• Modeling sediment and nutrient transport pathways based on water column and sediment property observations.
• Assessing the impact of agricultural runoff on estuary biogeochemistry based on the described study aims.
• Identifying zones of primary production and sediment accumulation based on the preliminary zonation concept for Keppel Bay.

Strengths

• Data includes observations from two distinct dry-season surveys, providing a temporal snapshot.
• Report structure suggests a detailed methodological approach covering water column, sediment properties, and incubations.

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 Australian estuary.
