Hamilton Harbour Water Quality Surveys for 2021

Hamilton Harbour in Ontario was monitored through 8 water quality surveys conducted between May and September 2021. The Ontario Ministry of the Environment, Conservation and Parks collected samples at 4 long-term monitoring stations. Measurements include nutrients, chlorophyll, suspended solids, and water column profiles.

Use Cases

• Analyze seasonal trends in phosphorus and nitrogen concentrations from May to September 2021.
• Model relationships between chlorophyll levels, secchi disc depth, and nutrient measurements.
• Compare water column profiles of temperature, dissolved oxygen, and pH across the 4 harbour stations.
• Assess spatial variability of suspended solids and reactive silicate between the centre station and harbour corners.

Strengths

• 8 distinct sampling events provide temporal resolution for the 2021 season.
• Data includes multiple parameter groups: nutrients, solids, chlorophyll, and physical water column profiles.
• Samples collected from two standard depths (1m and above sediment) plus a surface-integrated sample at the centre station.

Limitations

• Dataset is limited to a single year (2021) and one season (May-September).
• Sample size is constrained to 4 fixed monitoring stations within one harbour.
• Depth-integrated samples were only collected at the centre station, limiting spatial comparability for that method.
