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.
