| Summary: | (12'N, 9'N and 12'S) stations. Nor were surface nitrate 7 species made up 50% of the cell abundance. Margalef's Along one transect in the eastern equatorial Pacific Ocean biomass integrated to 200 in. Vertically the higher micro biomass maximum in most of the stations. Both the mean cell biomass per volume (pg C @M-3) decreased with depth because biomass, while coccolithophorids had similar importance to concentrations well correlated with micro-phytoplankton decreases with depth throughout the transect. The integrated diatom biomass in the upper 200 m of this transect did not diatoms. At each station 81 -137 species were found, but 2 - directly reflect the biogenic silica zone on the underlying diversity index peaked deeper than the microphytoplankton highest contributors to both the cell numbers and the microscope. In this size fraction, dinoflagellates were the numbers and biomass were trends near the surface followed by nutrient (NO3-) profiles except at the highest latitudes ocean'floor, and we attribute this discrepancy to the of the species composition and the different ratios of periodic El Nifio conditions. size and biomass per cell increased with depth, although the micro-phytoplankton (>15 gm in one dimension) biomass in the most recent El Nifio event and examined in the light the upper 200 in was examined. The samples were taken during Volume: Carbon in major taxonomic groups. Biomass profiles were not clearly related to water density ((Tt) or main |
