Results from a study of physiological responses of Ulva lactuca to ocean acidification and nutrient enrichmentAlpha = photosynthetic efficiency. A photosynthesis-irradiance (P-I) curve was generated using various photon flux densities from 0 – 700 uM photons m-2 s-1 for 200 seconds each, following a 200 second dark period to measure dark respiration rate. The maximum photosynthetic rate (Pmax), light saturation point (Ik), and photosynthetic efficiency (the initial slope of the P-I curve) (alpha) were determined from the P-I curves. Alpha
