Ballinderry River Dissolved Oxygen and Temperature Measurements Every 30 Minutes

High-frequency water quality data recorded every 30 minutes by a field probe in the Ballinderry River near Scotchtown Lane. The dataset contains provisional, non-validated measurements of dissolved oxygen (% saturation) and temperature (°C) collected by NIEA's Freshwater Monitoring and Assessment team. Data is loaded onto the public platform approximately every 30 days and is subject to revision due to environmental factors or sensor malfunction.

Use Cases

• Modeling diurnal and seasonal dissolved oxygen dynamics based on high-frequency 30-minute readings.
• Correlating water temperature fluctuations with dissolved oxygen saturation levels.
• Assessing provisional water quality trends for the Ballinderry River as part of long-term monitoring.
• Developing anomaly detection models for sensor malfunction using the stated accuracy specifications.

Strengths

• High temporal resolution with measurements recorded every 30 minutes.
• Sensor accuracy is specified as +/- 5% for dissolved oxygen and +/- 0.1 degrees C for temperature.
• Data is part of a long-term monitoring project with monthly maintenance and updates.

Limitations

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