Moyola River High-Frequency Water Quality Probe Data

Northern Ireland's Moyola River is monitored by a field probe deployed by the NIEA Freshwater Monitoring and Assessment team. The probe records Dissolved Oxygen (% saturation) and temperature (°C) every 30 minutes as part of a long-term project. Data is loaded publicly approximately every 30 days but is provisional and non-validated.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen cycles based on high-frequency 30-minute measurements.
• Analyzing water temperature trends in the Moyola River based on sensor data with +/- 0.1°C accuracy.
• Developing anomaly detection for sensor malfunction or environmental events based on provisional, real-time data streams.
• Correlating water quality parameters for freshwater ecosystem health assessments based on dissolved oxygen and temperature readings.

Strengths

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

Limitations

• Data is explicitly flagged as non-validated and provisional, subject to revision.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's total temporal coverage and row count are unknown.
