  abstract = {{T}he distribution of physical and chemical parameters and their impact on the biomass and abundance of phytoplankton in the {W}estern {P}acific ocean were compared in two opposing situations : the {E}l {N}ino {S}outhern {O}scillation ({ENSO}) event of 1987 and the no-{ENSO} period of 1988. {D}uring {E}l {N}ino conditions (september 1987), maximum cell abundance was recorded at 10°{S} at the boundary between the {S}outh {E}quatorial current ({SEC}) and the {S}outh {E}quatorial countercurrent ({SECC}). {I}n {S}eptember 1988, after the return of non-{ENSO} conditions, a well-established {E}quatorial upwelling produced an increase in the surface layer nutrient supply over 7° of latitude. {T}his in turn caused an increase in phytoplankton populations in the upper layer, with chlorophyll concentrations ... {I}ntegrated over 120 m, the cyanobacteria and microalgae populations were respectively 4.7. and 3.2 times larger than the year before. {O}n the other hand, transient nutrients inputs such as those observed at 10°{S} in {S}eptember 1987 caused a large increase in cyanobacteria populations (4.4. times) compared with those in neighbouring zones, and a somewhat smaller increase in microalgae populations (1.3 times)},
