Short summary
The ocean is one of the main reservoirs of carbon dioxide (CO2) on Earth's surface, so it plays an important role in modulating the climate. In this paper, we propose an update to how dissolved CO2 in seawater is determined from laboratory data, which can sometimes improve the accuracy of these measurements.
