Abstract

The work is devoted to the study of the effect of phycoerythrin pigment on the seawater optical properties in the Atlantic sector of the Southern Ocean. The investigation was carried out in the 79th expedition of the R / V “Akademik Mstislav Keldysh” in January 2020. At some stations, a high content of phycoerythrin was registered in the fluorescence spectra of seawater, the light absorption spectra by suspended particles, and in the remote sensed reflectance spectra of seawater. In particular, the fluorescence of this pigment induced by solar radiation was recorded in ocean color data. The presence of phycoerythrin can lead to uncertainties of the chlorophyll-a concentration estimates from satellite data retrieved with standard algorithms.
