Can Macro- and Micro-Nutrient Inputs Be Decoupled During Coastal Upwelling?
Abstract
Our goal is to understand two fundamental processes that affect surface water clarity in eastern boundary currents such as the California Current: (1) the injection of cold, nutrient-rich waters into the surface, which sustains phytoplankton blooms, and (2) resuspension of sediments by shelf circulation, which increases turbidity. We seek to test the hypothesis that water clarity is not only affected directly by sediment resuspension in coastal upwelling systems, but also indirectly because interaction of upwelling water with shelf sediments adds the micro-nutrient Fe required by phytoplankton.
