Phytoplankton pigment concentrations of seawater sampled during the Antarctic Circumnavigation Expedition (ACE) during the Austral Summer of 2016/2017.

***** Dataset abstract ***** This dataset contains phytoplankton pigment concentrations sampled during the Antarctic Circumnavigation Expedition (ACE) Leg 1-3 and analysed using high performance liquid chromatography. Water samples were collected from the underway seawater supply every 4 hours and at multiple depths from select CTD (conductivity, temperature and depth) rosette deployments. Pigment concentrations have been quality controlled. This circumpolar dataset contains the main pigment concentrations of phytoplankton and can be used to infer phytoplankton biomass and class composition. ***** Dataset contents ***** - ace_phytoplankton_pigments_20190906CURRSGCMR.csv, data file, comma-separated values<br> - ace_phytoplankton_pigments_lod.csv, metadata, comma-separated values<br> - data_file_header.txt, metadata, text<br> - README.txt, metadata, text Pigment concentration values below the limit of detection are reported with fill value ‘NaN’.
