This chapter provides an overview of the physical and biogeochemical factors that control spatial and temporal variability in macro- and micro-nutrient concentrations, phytoplankton biomass and production, and zooplankton biomass and grazing in the Indian Ocean. As in other ocean basins, in the Indian Ocean, there is a strong connection between the physics that drives (or suppresses) nutrient delivery to the photic zone and the responses of phytoplankton and zooplankton. Monsoon wind forcing is a major biogeochemical and ecological driver with broad stimulatory and suppressing effects throughout many regions, including the Arabian Sea, Bay of Bengal, Seychelles Chagos Thermocline Ridge, Java, and the central/eastern subtropical gyre. In addition, there are regionally specific processes that significantly modulate the biogeochemical and ecological responses. For example, strong advective impacts and Fe/Si limitation in the Arabian Sea; freshwater and stratification in the Bay of Bengal; poleward transport, downwelling, and seaward-propagating eddies in the southeastern Indian Ocean; and alongshore-propagating eddies, meanders, upwelling and poleward transport in the southwestern Indian Ocean. The southern subtropical gyre is extremely oligotrophic except when/where the Southeast Madagascar bloom occurs. Recommendations for future work include the need to motivate more planktonic food web studies.
