Trichodesmium erythraeum growth rates per day for all replicates in each treatment calculated from cell counts. Trichodesmium erythraeum was grown in biological triplicate under two CO2 regimes (380 and 750 uatm pCO2) and four different nutrient regimes (replete, phosphorus-limited,iron-limited, iron/phosphorus colimited).
