  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">These data contain concentrations in micrograms per litre (ug/L) of the 
individual accessory pigments of phytoplankton measured by High Performance 
Liquid Chromatography (HPLC). Pigment samples were taken on Cefas fisheries 
surveys in the Celtic Seas, and sent to DHI laboratory in Denmark for HPLC 
analysis. Data was then sent back to Cefas and matched with metadata and 
quality controlled. Chlorophyll concentrations from this dataset have a 
variety of uses: for assessment of concentrations for purposes such as 
eutrophication assessments, validation of remote sensing derived chlorophyll 
estimates, as a proxy for phytoplankton biomass, or to calibrate fluorometers. 
Pigment concentrations can be applied like a fingerprint to derive 
phytoplankton functional types and give information about the phytoplankton 
community.</dc:description>
