Abstract:
Samples were collected in the surface ocean of the South East Pacific Ocean in subtropical and sub-Antarctic water masses, above the Chatham Rise and at the entrance of the Cook Strait in well mixed water masses, creating distinct oligotrophic and eutrophic regimes, respectively. Regimes manifested in nutrient profiles, phytoplankton, and bacterial abundances, as well as in Chlorophyll a concentration, which are separated by size fractions.
