    • Three marker pigments were used for determining distributions of the major phytoplankton taxa: fucoxanthin for diatoms, 19′-hexanotyoxyfucoxanthin for haptophytes (primarily P. antarctica), and alloxanthin for cryptophytes. In samples dominated by each of these phytoplankton taxa, the molar ratio of the corresponding marker pigment to chlorophyll a was approximately 1:1. Therefore, the relative abundance of each phytoplankton taxon in terms of chlorophyll a could be calculated as the marker pigment concentration divided by the sum of all three marker pigments. Taxonomic identifications were confirmed by microscopy.
