WFD Cycle 2 TraC Dissolved Oxygen Classification for UK Waters

Environment Agency data classifies Dissolved Oxygen (DO) levels in transitional and coastal water bodies for Water Framework Directive (WFD) purposes. Observed 5th percentile DO values are compared against predicted pristine values to assign a classification of High, Good, or Moderate. This dataset has been retired and superseded by a newer record.

Use Cases

• Assess ecological status of transitional and coastal waters based on dissolved oxygen levels.
• Compare observed water quality against predicted pristine conditions using the 5th percentile metric.
• Support regulatory reporting for the Water Framework Directive based on physico-chemistry classifications.

Strengths

• Data originates from the UK Environment Agency, an authoritative source for environmental monitoring.
• Classification methodology is explicitly described, comparing observed and expected 5th percentile DO values.

Limitations

• Dataset is retired and superseded by a newer record, indicating it is not current.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data may reflect geographic bias inherent to UK monitoring programs.
