  • Surface waters of the eastern equatorial Pacific Ocean present the enigma of apparently high plant-nutrient concentrations but low phytoplankton biomass and productivity. One explanation for this ‘high-nitrate, low-chlorophyll’ (HNLC) phenomenon has been that growth is limited by iron availability,. Here we use field data and a simple silicon-cycle model to investigate the HNLC condition for the upwelling zone of this ocean region. Measured silicate concentrations in surface waters are low and… CONTINUE READING
