The manuscript by Skinner et al. presents a unique and useful data compilation of ocean-atmosphere radiocarbon age offset (B-Atm) across the last deglaciation. The presented global average B-Atm represents a new benchmark for modelling studies seeking to constrain the ocean's role in past atmospheric CO2 change, and seeking closure of the global radiocarbon cycle. The latter is important for constraining the carbon cycle evolution over the last deglaciation (which remains to be quantitatively accounted for), as well as the history of the geodynamo and solar activity.

This paper presents two new long-term SST records from the south Atlantic Ocean. This region is marked by the strong ocean baroclinicity and associated SST gradient, and is key to understanding late Cenozoic Antarctic glaciation and deep ocean circulation. These records have the potential to significantly contribute to address those questions.
