Keppel Bay Biogeochemical Zones: Dry-Season Water and Seabed Properties

Two dry seasons of water column and seabed property data from Keppel Bay, Australia, collected by the Australian Ocean Data Network. The study explores nutrient sources and transformations, dividing the bay into three functional zones based on geochemistry and hydrodynamics. Supplementary core incubations measured carbon decomposition rates and nutrient fluxes.

Use Cases

• Modeling benthic-pelagic nutrient coupling based on the described conceptual model of three biogeochemical zones.
• Analyzing the relationship between suspended sediment and phytoplankton growth limitation based on light and nutrient data.
• Mapping spatial variation in seabed geochemistry and water column properties within a small coastal system.

Strengths

• Data collection spans two distinct dry seasons, providing temporal context.
• Integrates multiple measurement types: water column properties, seabed geochemistry, and core incubations.
• Analysis defines three distinct functional zones (ZMR, CTZ, BWZ) based on integrated parameters.

Limitations

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