The data were obtained by Dr Huw Pullin, Cardiff University as part of a UKRI funded research project. Experiments were conducted under controlled temperatures (20degC), and CO2 pressures (5 and 50% v/v at 1 atm).

During the experiments, either ~3.14 L or ~1.57 L was added to maintain a high (~1:4.4) or low (~1:10) volume ratio of liquid to gas, respectively. Pressure in the headspace was maintained at 1 atm. Two different initial gas compositions were used, with 5% and 50 % (v/v) CO2. Composition in the headspace was monitored continuously using a Gem Scientific G110 infrared CO2 analyser (calibrated to ISO17025 ±1% accuracy), and 100 mL liquid was sampled periodically by an external peristatic pump for alkalinity measurement.
