Historical Water Bottom Quality Measurements from National Monitoring Program

Historical measurement data on the physico-chemical and chemical quality components of the Water Bottom of national waters. The data is stored in DONAR and originates from the National Measurement Programme Monitoring Water Management (MWTL). It forms part of the Water Quality — Chemical series alongside Surface Water and Floating Dust datasets.

Use Cases

• Analyzing long-term trends in water bottom chemistry based on historical measurement data.
• Modeling the relationship between water bottom and surface water quality as part of the described series.
• Assessing environmental compliance or changes in national waters based on the monitoring program parameters.

Strengths

• Data originates from a structured national monitoring program (MWTL), suggesting systematic collection.
• Forms a series with related Surface Water and Floating Dust datasets, enabling broader environmental analysis.
• Published under a permissive public domain license (CC-PDM-1.0).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and temporal coverage are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
