What have we done about it?
•Increased sophistication of satellite algorithms
•Addition of phytoplankton functional groups
•Addition of elements
•Increased realism of physical models
–Spatial resolution (mesoscale eddies)
–Temporal variability (El Nino; NAO; PDO)
–Better physics (Gent-McWilliams; KPP)
•Distinguishing regions of nitrogen, phosphorus, silicon and iron limitation
