Keppel Bay Biogeochemical Zones and Nutrient Data from Dry Seasons

Water column and seabed property measurements from Keppel Bay, contiguous with the Great Barrier Reef Lagoon, collected over two dry seasons. The dataset explores nutrient sources and transformations, defining three functional process zones based on geochemistry and hydrodynamics. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classifying coastal biogeochemical zones based on seabed geochemistry and water column characteristics.
• Modeling nutrient fluxes and carbon decomposition rates in a fluvial-marine transition area.
• Analyzing the relationship between suspended sediment, light penetration, and phytoplankton growth limitation.
• Developing conceptual models integrating benthic and pelagic processes for systems resembling fluidised bed reactors.

Strengths

• Data integrates water column and seabed properties for a holistic view.
• Measurements were taken over two distinct dry-season periods.
• Supplementary core incubations provide direct carbon decomposition and nutrient flux rates.
• The study defines three distinct biogeochemical zones (ZMR, CTZ, BWZ) with clear functional characteristics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a dry-season perspective; wet-season dynamics are not covered.
