  abstract = {{M}odel simulations and remote sensing observations show that ocean dynamics at fine scales (1-100 km in space, day-weeks in time) strongly influence the distribution of phytoplankton. {H}owever, only a few in situ-based studies at fine scales have been performed, and most of them concern western boundary currents which may not be representative of less energetic regions. {T}he {PROLENSMED}-{SWOT} cruise took place in the moderately energetic waters of the western {M}editerranean {S}ea ({WMS}), in the region south of the {B}alearic {I}slands. {T}aking advantage of nearreal-time satellite information, we defined a sampling strategy in order to cross a frontal zone separating different water masses. {M}ulti-parametric in situ sensors mounted on the research vessel, on a towed vehicle and on an ocean glider were used to sample physical and biogeochemical variables at a high spatial resolution. {P}articular attention was given to adapting the sampling route in order to estimate the vertical velocities in the frontal area also. {T}his strategy was successful in sampling quasi-synoptically an oceanic area characterized by the presence of a narrow front with an associated vertical circulation. {A} multiparametric statistical analysis of the collected data identifies two water masses characterized by different abundances of several phytoplankton cytomet- ric functional groups, as well as different concentrations of chlorophyll a and {O}-2. {H}ere, we focus on moderately energetic fronts induced by fine-scale circulation. {M}oreover, we explore physical-biological coupling in an oligotrophic region. {O}ur results show that the fronts induced by the finescale circulation, even if weaker than the fronts occurring in energetic and nutrient-rich boundary current systems, maintain nevertheless a strong structuring effect on the phytoplankton community by segregating different groups at the surface. {S}ince oligotrophic and moderately energetic regions are representative of a very large part of the world ocean, our results may have global significance when extrapolated.},
