Seasonal Water Quality at Two Sites in the Swan River Estuary, Western Australia

Seasonal variations in major ions, nutrients, and chlorophyll a were examined at two sites in the upper Swan River estuary. The data likely contains measurements of temperature (13-29°C), salinity (3-30), turbidity, and nutrient concentrations influenced by riverine discharge and salt wedge dynamics. The dataset is provided by the Australian Ocean Data Network via data_gov_au and was last updated in April 2026.

Use Cases

• Modeling phytoplankton growth limitation based on nutrient ratios and concentrations mentioned in the description
• Analyzing the relationship between riverine discharge, salinity, and conservative ion behavior described in the study
• Investigating anoxia and nutrient regeneration in stratified bottom waters associated with salt wedge propagation
• Studying the impact of groundwater flow and sediment processes on water column nutrient transport

Strengths

• Data captures a wide intra-annual range for key parameters like temperature (13-29°C) and salinity (3-30)
• Focus on two distinct sites allows for comparative analysis of depth-dependent phenomena like anoxia
• Description provides a detailed mechanistic context linking physical stratification (salt wedge) to chemical changes (nutrient concentrations)

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, being specific to one estuary
