Chlorophyll data was used to measure growth rates of sea ice algae in CO2 incubations. Sea ice brine microalgae was collected from sackholes. Replicate samples were incubated in ambient air (~0.04% CO2), 0.1% CO2, 1.0% CO2 and 2.0% CO2 concentrations. Three incubation experiments were carried out at SIPEX stations 4 (expt 1) 7 (expt 3) and 8 (expt 4). Growth rate calcualtions followed a standard exponential growth model, i.e Bf = Bi x e(rt) Where Bf equals final biomass, Bi equals initial biomass, r = growth rate and t = time (in days).
