Phytoplankton pigment concentrations measured by HPLC and estimated from underway spectrophotometry, and the particulate absorption and attenuation spectra derived from underway spectrophotometry during POLARSTERN cruises PS93.2, PS99.2 and PS107@en

We present data sets on:
1) the concentrations of various phytoplankton pigments (unit: mg/m³) from discrete samples measured using High Pressure Liquid Chromatography (HPLC);
2) the concentrations of various phytoplankton pigments (unit: mg/m³) estimated from underway AC-S particulate absorption data (Fucoxanthin, 19'-hexanoyloxyfucoxanthin and Diadinoxanthin are estimated using SVD-NNLS-9 matrix inversion method; total Chlorophyll a, b, Chlorophyll c1+2, photosynthetic and photoprotective carotenoids are estimated using Gaussian decomposition); and […]
