This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Dissolved Oxygen (DO) in transitional and coastal water bodies. Physico-chemistry, in this case Dissolved Oxygen, is a supporting element that underpins the ecological status of a transitional or coastal water body. Data consisting of DO and salinity records are run through the Dissolved Oxygen Water Framework Directive (WFD) classification tool. The actual (observed) 5%ile values of DO are compared with a predicted 5%ile value at average salinity in transitional waters, or with fixed values in coastal waters, that reflect pristine conditions. The comparison between the observed and expected 5%ile values of DO are used to produce a DO classification (High, Good or Moderate only) of a transitional or coastal water body for WFD purposes.

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
