Última Étude de la production primaire phytoplanctonique dans les eaux littorales de la côte normande (Manche orientale) ArchiMer Gros, Philippe; Ryckaert, Mireille. A phytoplankton community was sampled monthly between February 1978 and January 1980 in a coastal area of the Eastern Channel. During each croise, measurements of several physico-chemical and biological factors were also carried out. This data basis permitted the description of the ecosystem's behaviour in a synthetic manner by inertia analysis techniques, which draw up an ordination of the components of the spatio-temporal variability of the coastal pelagie biotope. For the given time-and space-steps of our sampling strategy, it is shown that the major source of variation is seasonal. This determines the preferential observational scale of the study, whose aim is the analysis 'Of the variability of the low-frequency processes of primary productivity. The...

The composition of ultraphytoplankton (10 m) sampled in surface waters (1 m depth) was investigated during summer 2010 in the Bay of Marseille (NW Mediterranean) using flow cytometry. In addition to groups of Synechococcus, Prochlorococcus, picoeukaryotes and nanoeukaryotes, an unidentified additional cluster was observed. The particles forming this cluster had a high abundance (7 10(4) events mL(1)), with both orange and red fluorescence intensities like Synechococcus, but with a size signal larger than that of 2 m fluorospheres (beads). These unknown particles were sorted out by flow cytometry and then observed by epifluorescence microscopy: they appeared to be chain-forming microorganisms, just like trichomes of some diazotroph cyanobacteria with one...
