Palacios and Zimmerman (2007)

Leaf biomass of eelgrass (Zostera marina) grown for one year at a pH of 7.75 (control = 8.1) under light-limited conditions (5% of surface irradiance). Reduced pH conditions were obtained via the addition of CO2 from industrial fluegas containing 10% CO2, 158ppm CO and 58 ppm NOx. Seawater temperature ranged from 9C in winter to 17C in summer and salinity ranged from 34 to 37.
