“…1, Table 2). The pigment composition of C. polylepis is similar to that of the Prymnesiophyte Emiliana huxleyi (Wright & Jeffrey 1987), but differs from the Plymouth isolate of C. polylepis because 2 recently found pigments in our strain (Bjerkeng et al 1990) are absent in that strain (Riley & Wilson 1967). Similar to the findings of Riley & Wilson (1967), our strain exhibits minor amounts of a carotenoid eluted after diatoxanthin (Table 1.…”

The photobiological response of an isolate of the prymnesiophyte Chrysochromulina polylepis, obtained from a bloom in the Skagerrak in May-June 1988, was evaluated with respect to pigment composition, spectral dependence of light harvesting, and photosynthetic parameters of cultures grown at 75 to 120 gm01 m-2 S-' irradiance, 16 h day length and 15°C. Results were compared to similarly grown cultures of the diatom Skeletonerna costatum that appeared before and after the C. polylepis bloom. Chl a-specific absorption of light ("a,) and chl a-specific absorption of quanta transported to photosystem 11, estimated by means of a scaled fluorescence excitation spectrum ("F), were 1.7 to 2.1 times larger in C. polylepis than in S. costatum in the visible spectrum. C. polylepis harvested blue-green light (450 to 500 nm) particularly efficiently. This is related to a high proportion of 19'-hexanoyloxyfucoxanthin and chl c3 relative to chl a. Nonetheless, both C. polylepis and S. costatum absorb light more efficiently in 'clearest' blue ocean water than in 'clearest' green coastal water according to calculations based on spectrally corrected absorbed quanta transported to photosystem I1 ("F). Carbon-specific light absorption was about the same in the 2 species since the chl a : C ratio in S. costatum was twice as high as in C. polylepis. C. polylepis had a much smaller maximum carbon uptake (P:) than S. costatum. Differences between the 2 species in terms of photosynthetic parameters, pigment composition, and spectral characteristics normalized to chl a, carbon, and cell are discussed.

“…Nevertheless we tried to approximate phytoflagellate biomass by using indicator pigments from the Prymnesiophyceae, Dinophyceae and green algae. When we consider a mean chl b to chl a ratio of 0.5 (w/w) in green algae (Riley and Wilson 1967) the phytoplankton biomass of the stations of cluster group 2 would contain not more than 7.5% green algae (concentration chlb/(concentration chl a.0.5).100%). The stations of the other cluster groups would contain less than that, with a maximum of 4.7% at station PR 9.…”

“…19'-hexanoyloxyfucoxanthin is a typical prymnesiophycean pigment, but it is not found in all members of the class Bj~rnland et al 1988). Furthermore the relative proportion of a specific pigment to chlorophyll a or to cell carbon can differ from strain to strain or from species to species, as has been demonstrated for diatoms (Gallagher and Alberte 1985;Klein 1988), Chlorophyceae (Riley and Wilson 1967), Chrysophyceae (Withers et al 1981) and Dinophyceae (Jeffrey et al 1975). Finally the pigment composition of a phytoplankton cell is variable, depending on the physiological state of the cell and environmental conditions like nutrients, temperature, lightintensity and quality (Carreto and Catoggio 1976;Gallagher and Alberte 1985;Klein 1988;Kana et al 1988;Coats and Harding 1988).…”

Algal pigment patterns in different watermasses of the Atlantic sector of the Southern Ocean during fall 1987

et al. 1990

Summary. During the autumn of 1987 a survey was carried out in the Atlantic sector of the Southern Ocean in order to study phytoplankton community structure in relation to hydrological features. The positions of the boundary zones, determined by means of hydrological and chemical properties (especially silicic acid) match with previous studies. The phytoplankton community structure was studied by means of algal pigment fingerprints. A cluster analysis of the main phytoplankton pigments revealed the presence of four distinctive phytoplankton communities in the area. In three cluster groups phytoflagellate pigments of different taxonomical groups were found which showed different relative abundance between the cluster groups. In between the Polar Front Zone and the Weddell Scotia Confluence a fourth group was found which was rich in diatoms as compared to the other cluster groups. High concentrations of the fucoxanthin related 19'-hexanoyloxyfucoxanthin indicated the relative importance of Prymnesiophyceae during fall in this area. The relative contribution of each taxonomical group to total phytoplankton biomass was estimated by using specific pigment ratios. This calculation showed that in this time of the year phytoflagellate biomass (especially Prymnesiophytes) surpasses diatom biomass.

“…When it was fed to veligers of Nassarius reticulatus and Rissoa inconspicua with unpigmented digestive glands, pigments from the alga soon coloured the gland brown, the carotenoids, mainly fucoxanthin and neofucoxanthin (Riley & Wilson, 1967), masking the green of the chlorophylls a and c. However, the brown pigments were soon excreted, rapidly in Rissoa, leaving the gland green. A colourless gland has been recorded for Rissoa parva and Caecum imper-foratum but most frequently for Lamellaria perspicua and L. latens.…”
