Abstract
Picoplankton are phytoplankton between 0.2 and 2.0 μm in diameter that
contribute significantly to marine primary productivity. We investigated the distributions
of two genera of picoplankton, Prochlorococcus and Synechococcus, in the nearshore
environment of Māmala Bay, Oʻahu. The focus of this study is to analyze the influences
on the vertical distribution of the two populations. Picoplankton samples from each site
were counted with a flow cytometer, these counts were compared to environmental
factors: nutrients, chlorophyll, and Photosynthetically Active Radiation (PAR). Both
Prochlorococcus and Synechococcus distributions are influenced by all these factors,
especially nutrients and mixing events. Both populations follow a specific pattern that is
unique to nearshore ecosystems in the subtropical North Pacific Ocean dictated by the
underlying nutricline and seasonal variability in Māmala Bay.
