  abstract = {{T}he present description of {T}richodesmium spp. population dynamics and associated environmental variables is the first one using a very short sampling interval (2-3 days). {S}uch a strategy allows a fine description of changes involving the population density and characteristics. {I}t also tends itself to interpreting those changes from past environmental conditions. {D}uring the two surveys, 2 and 5 month-long, {T}. erythraeum dominated the {T}richodesmium population, with temporary occurrence of {T}. thiebautii and five blooms could be described. {T}hese events appeared at temperatures >24 degrees {C} and followed, in all cases, nitrate, soluble reactive phosphorus and chlorophyll a enrichments, with a 3-7 day time lag. {L}ow wind speed (<4 m s(-1)) was not a prerequisite for {T}richodesmium bloom developments as long as temperatures exceeded 26 degrees {C}. {A}s abundance increased during the bloom, so did the number of filaments (trichomes) in colonies and their buoyancy, leading to a clear positive biomass gradient from the bottom to the surface. {A} simple model, using variable growth rates, showed trichome ascent would be responsible for 87-99% of concentrations at 0.5 m, with {T}richodesmium net growth rates ranging from 0.11 to 0.38 d(-1). {F}inally, rapid trichome density declines could be ascribed to nutrient depletion and massive surface death following ascent.},
