“…The concentration of peridinin, which is uniquely associated with dinoflagellates, was 2 ng liter-' in the mixed layer and had a sharp maximum of 15 ng liter-l at 55 m (the highest concentration of peridinin I observed at the OFP station), and a broad maximum at 100 m. Alloxanthin, which is uniquely associated with cryptophytes, was almost undetectable in the upper 50 m and below the SCM, but had a sharp concentration maximum of 10 ng liter-l at the SCM. Prasinoxanthin, a biomarker for prasinophytes (Foss et al 1984), was not detected at this time of the year. Violaxanthin, a biomarker for chlorophytes, was only present in trace amounts (<2 ng liter-l) throughout the water column.…”

The response of phytoplankton community structure and dynamics to varying physical forcing was studied at a station southeast of Bermuda over a period of 18 months. The dominant groups of algae, as delineated by taxonspecific carotenoids, were prymnesiophytes, pelagophytes, and cyanobacteria. Other groups such as diatoms, dinoflagellates, prasinophytes, chlorophytes, and cryptophytes were never abundant. Although phytoplankton biomass varied over the year with maxima in the winter, likely in response to elevated nutrient concentrations, the composition of the eucaryotic phytoplankton community and the relative biomass of cyanobacteria in the surface layer did not change. The distribution of phytoplankton biomass and primary production over five size classes was virtually constant over the year as well: picoplankton (<3 Frn) contributed 79% to total Chl a and primary production. Taxon-specific phytoplankton growth rates were measured using the pigment-labeling method. Growth rates of prymnesiophytes and pelagophytes did not vary systematically over the year; rates in the surface layer ranged from 0.2 to 0.6 d-l, declining to values

“…The order Mamiellales, with MM gilva as the type, was described by Moestrup (10) on the basis of the lack of an inner layer of square or diamond-shaped scales. Recently, Guillard (8) proposed to emend the circumscription of the order Mamiellales to include coccoid prasinophytes containing prasinoxanthin and Mg 2,4-D, since the presence of both pigments was the typical characteristic of the Mamiellales as exemplified in the above-mentioned three genera (6)(7)(8).…”

“…comm.). Additional information regarding pigment ratios for prasinophytes came from Foss et al (1986), Hooks et al (1988), and our own culture of Pycnococcus provasolii (CCMP1198). Pigment ratios for Pro and Syn in the northern section were derived from the analysis of surface samples collected in the SPG where concentrations of pigments from eukaryotic algae (e.g.…”
