Water Framework Directive (WFD) TRaC Waterbody Phytoplankton data

This data collates all the Phytoplankton samples collected within Wales from 2007 onwards that have been used for the WFD TRaC Phytoplankton assessment tool. This methodology is based on the principle that additional nutrients (especially nitrogen) can alter the amount of phytoplankton in transitional waters. Persistent and high counts of phytoplankton taxa are also seen as a measure of disturbance in the phytoplankton community. Phytoplankton samples are usually sent to a specialist marine contractor for Species Identity and abundance (two labs have been used in this time period; CEFAS 2007 – 2009 & APEM 2010 – onwards). Phytoplankton samples are analysed (identified and counted) using the Utermöhl method. Phytoplankton cells are identified to the lowest practical taxonomic level possible. UK WFD authorities use a revised phytoplankton list (refer to the relevant WFD Agency for the current list). The resultant data is processed through a phytoplankton tool to provide a phytoplankton assessment that can be used to WFD Classification of TraC water bodies. Further information is available from the UK-TAG WFD website.

Lineage

The change in analytical lab in 2010 resulted in the new laboratory reporting increased abundances of species because of the more high-powered microscopes available. There were also inconsistencies in recording Phaeocystis as either cell counts or colony counts (colony counts are not used by the tool).
