Table 11.1 Summary of the ocean acidii cation mesocosm experiments performed at the Bergen Large-scale Facility, Raunefjord, Norway in 2003, 2005, and 2006, including date and duration of experiment,
initial nutrient concentrations, total mean and maximum (Max.) mean chlorophyll (Chl) a, DMS, and particulate DMSP (DMSPp) concentrations under high (~700-750 μatm) and present-day p CO 2 (~380 μatm).
Total mean = the mean of all data from all mesocosms of each CO 2 treatment. Max. (mean) = the mean of the maximum values measured in all mesocosms of each CO 2 treatment.
