Holcomb et al. (2012)

Calcification rates of zooxanthellate Northern Star Coral (Astrangia poculata) colonies grown under normal and reduced pH conditions. Salinity was approximately 32 ppt, temperature was 24C, and pH was altered by the addition of CO2. Data obtained from Figure S8.

Holcomb et al. (2012)

Calcification rates of zooxanthellate Northern Star Coral (Astrangia poculata) colonies grown under normal and reduced pH conditions, as well as at elevated nutrient levels. Salinity was approximately 32 ppt, temperature was 24C, and pH was altered by the addition of CO2. Data obtained from Figure S8.
