ABUNDANCE OF CRYPTOPHYCEAE AND CHLOROPHYLL B-CONTAINING ORGANISMS IN THE WEDDELL-SCOTIA CONFLUENCE AREA IN THE SPRING OF 1988
During a cruise in the Weddell-Scotia Confluence area (EPOS Leg 2: November-January 1988/1989) nanophytoplankton composition was determined by employing taxon-specific pigment measurements with HPLC. The biomass of the most important components was estimated by using specific pigment ratios measured...
