Ameliorating ocean acidification: towards a model relating pCO2, irradiance and leaf area index of Zostera marina (eelgrass) in Padilla Bay, WA
In nearshore, soft-sediment habitats of the Salish Sea, eelgrass (Zostera marina L.) meadows have been identified as potential mitigators of ocean acidification (OA) because their photosynthetic activity can decrease pCO2, increase pH and provide refuge for organisms sensitive to OA. The diurnal lig...
