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 3) the spectral particulate absorption and attenuation coefficients and their standard deviation (unit: 1/m) derived from underway AC-S measurements during the cruises PS93.2, PS99.2 and PS107 on R/V POLARSTERN in the Fram Strait.
