P.43 left column top paragraph:"The integrated growth rates for the upper 150 m of the water column were quite similar at all locations (Table 1) and corresponded to previous estimates at 140˚ W (Vaulot et al. 1995, Binder et al. 1996). Together, high growth rate and abundance in these oligotrophic waters (Table 1) imply that Prochlorococcus was not nutrient-limited at the oligotrophic W-EqPac Station or at Station ALOHA." P.45 right column 3rd paragraph:"Evidence to suggest that Station ALOHA in the subtropical North Pacific gyre is more oligotrophic than W-EqPac is based on nutrient and primary production data. First, the nitracline, which is defined as the shallowest depth of first appearance of 0.1µM N02+N03, is deeper at Station ALOHA than at WEqPac (Table 1). Second, the depth-integrated N02+N03 in the upper 150 m of the water column was 57µmol/cm^2 at W-EqPac, but only 2.8 to 5.3µmol/cm^2 at Station ALOHA. Third, the depth-integrated chlorophyll concentration and primary production at WEqPac was higher than that at Station ALOHA (Table 1)." |
