Abstract

Here, we examine cyanobacteria diversity along an understudied transect of the North Pacific Ocean. Nine surface-seawater samples were analyzed using PCR of the Prochlorococcus ITS region and high-throughput DNA sequencing. We discovered distinct regions of HL-I Prochlorococcus, HL-II Prochlorococcus, and Synechococcus along the transect. When superimposed beside the temperature and salinity gradients recorded along the transect, clear patterns emerge that suggest an important relationship between sea-surface temperature and the Prochlorococcus ecotypes that are abundant in the North Pacific Ocean.
