The importance of adding unbiased Argo observations to the ocean carbon observing system.

ABSTRACT: The current coverage of direct, high-quality ship-based observations of surface ocean pCO₂ includes large gaps in time and space, and has been declining since 2017. These ocean observations provide the basis for the data products that reconstruct surface ocean pCO₂ and estimate ocean carbon uptake. Improved data coverage is needed to advance our understanding of the ocean carbon sink and air-sea CO₂ exchange. Targeted sampling from autonomous platforms, such as biogeochemical floats, combined with traditional shipboard measurements represents a promising path forward to improve surface ocean pCO₂ reconstructions. However, floats provide indirect pCO₂ estimates derived from pH, and thus have higher uncertainty and are biased compared to
