We investigated the growth rates of Prochlorococcus and Synechococcus spp. and their
relative contributions to carbon production at five stations in the Arabian Sea during the late
Southwest and early Northeast Monsoon seasons in 1995. Estimates of Prochlorococcus
growth rates were based on diel cell cycle analysis. Accurate determination of the duration
of the cell cycle terminal event, eg, tg., was not possible for Synechococcus because of its
highly variable cell cycle patterns (eg, imperfect phasing, multiple DNA-replication peaks …
