Keppel Bay Biogeochemical Zones and Nutrient Data from Dry-Season Surveys

Geoscience Australia Data collected water column and seabed property data over two dry seasons in Keppel Bay, Australia. The study explores nutrient sources and transformations, defining three functional process zones based on bathymetry and hydrodynamics. Supplementary core incubations measured carbon decomposition rates and nutrient fluxes.

Use Cases

• Modeling benthic-pelagic coupling based on the described seabed geochemistry and water column nutrient characteristics.
• Classifying coastal marine environments into functional zones based on the integrated conceptual model of bathymetry and hydrodynamics.
• Studying phytoplankton growth limitations (light, N, P) in different zones of a macrotidal bay.
• Analyzing the impact of terrestrial organic matter mineralisation in zones of maximum resuspension.

Strengths

• Data collection spans two dry seasons, providing temporal context.
• Integrates multiple measurement types: water column properties, seabed geochemistry, and core incubations.
• 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.
