Blackwater River Dissolved Oxygen and Temperature Measurements at Maghery

High-frequency water quality data recorded every 30 minutes by a field probe at the foot of the Blackwater River. The NIEA Freshwater Monitoring and Assessment team deployed the probe, which measures dissolved oxygen saturation with +/- 5% accuracy and temperature to +/- 0.1°C. Data is provisional, updated monthly, and was last loaded to the platform on March 18, 2026.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen cycles based on 30-minute interval data.
• Correlating water temperature fluctuations with dissolved oxygen saturation levels.
• Assessing provisional water quality trends for the Blackwater River tributary of Lough Neagh.
• Validating sensor performance for high-frequency environmental monitoring projects.

Strengths

• High temporal resolution with measurements recorded every 30 minutes.
• Sensor specifications are provided, including dissolved oxygen accuracy of +/- 5% and temperature accuracy of +/- 0.1°C.
• Data collection is part of a long-term monitoring project, suggesting temporal depth.

Limitations

• Data is explicitly noted as non-validated and provisional, subject to revision.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
