Biogeochemical Zones of Keppel Bay: A Dry-Season Perspective

Keppel Bay, contiguous with the Great Barrier Reef Lagoon, is studied for nutrient and sediment dynamics from the Fitzroy River. The dataset likely contains water column and seabed properties, including carbon decomposition rates and nutrient fluxes, measured over two dry seasons. It was published by the Australian Ocean Data Network and last updated on 2026-04-28.

Use Cases

• Modeling benthic-pelagic coupling based on the integrated conceptual model of seabed geochemistry and water column nutrients.
• Classifying coastal hydrodynamic zones based on the described zone of maximum resuspension, coastal transitional zone, and blue water zone.
• Analyzing phytoplankton growth limitations based on light penetration and nutrient (N and P) availability data.
• Studying terrestrial organic matter mineralization in macrotidal systems based on measurements from core incubations.

Strengths

• Data integrates multiple components: water column nutrients, seabed geochemistry, and core incubation measurements.
• Study spans two dry seasons, providing a temporal perspective on dry-season conditions.
• Conceptual model is grounded in specific bathymetric and hydrodynamic characteristics of the bay.

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 specific temporal bias, covering only dry-season conditions.
