  abstract = {{C}ontributions of filamentous and picoplanktonic cyanobacteria to the phytoplankton community structure were examined in {N}ew {C}aledonian waters during the 2001-2003 {E}l {N}ino period at 2 ocean stations ({L}oyalty {C}hannel and {S}antal {B}ay) and 1 coral-reef lagoon station ({O}uinne). {M}orphometric characteristics of diazotrophic filamentous cyanobacteria are given, as well as the seasonal and inter-annual variations of their surface areas and integrated abundances. {T}richodesmium tenue and {T}. thiebautii were the dominant species followed by {T}. erythraeum, altogether accounting for more than 51-80% of the biomass of the free-living filamentous cyanobacteria. {K}atagnymene spp. accounted for a smaller percentage (<13.8% at ocean stations, <3.6% in the lagoon). {R}ichelia intracellularis biomass was relatively small (<1 % of total surface area and volume of {T}richodesmium trichomes), with the highest concentration observed in summer (735 trichomes 1(-1)). {C}olonies of unidentified cyanobacteria composed of spherical cells accounted on average for <1 % of the {T}richodesmium biomass, with maximum values exceeding 4000 cells 1(-1). {A}bundance of filamentous cyanobacteria varied according to environmental factors; summer 2001-2002 was characterized by low filamentous diazotroph abundance, and summer 2003, at the peak of the 2001-2003 {E}l {N}ino, was particularly rich in filamentous cyanobacteria (with a maximum {T}richodesmium spp. abundance of 4500 trichomes 1(-1) in the {L}oyalty {C}hannel). {A} similar variability pattern was observed for large diatoms and dinoflagellates, and for all picoeukaryotic populations. {D}ifferent biomass estimators are provided, including cell abundances, pigment concentrations including chlorophylls and phycoerythrin, and carbon content.},
