  <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 Pressure 
Liquid Chromatography (HPLC). Pigment samples were taken primarily on Cefas 
fisheries and SmartBuoy cruises in the North Sea and 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>
