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.
