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

Seasonal variations in major ions, nutrients, and chlorophyll a were examined at two sites in the upper Swan River estuary. The data shows intra-annual variations strongly influenced by seasonal riverine discharge, with temperature ranging 13-29°C and salinity 3-30. The dataset was provided by the Australian Ocean Data Network and last updated in 2026.

Use Cases

• Modeling phytoplankton growth limitation based on nutrient ratios and absolute concentrations mentioned in the description.
• Analyzing the relationship between riverine discharge, salt wedge propagation, and bottom water anoxia described in the study.
• Investigating the impact of groundwater flow on sediment porewater nutrient transport into the water column as suggested in the description.
• Studying seasonal physico-chemical stratification of surface and bottom waters in an estuary.

Strengths

• Data captures a wide seasonal range of temperature (13-29°C) and salinity (3-30).
• Description details specific biogeochemical processes like nutrient regeneration from flocculation and N:P ratios (3-8).
• Focus on two distinct sites allows for spatial comparison within the estuary.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Freshness should be verified as the last update timestamp is 2026-06-04.
