Southern Ocean CO2 flux in 2019

Carbon dioxide (CO2) flux determined from USV measurements during the 2019 USV mission to the Southern Ocean. Blue colors (negative) indicate ocean CO2 uptake; red colors (positive) indicate outgassing. Black lines indicate climatological position of major oceanic zones that are separated by sharp gradients in temperature and salinity. Credit: Figure 2 from Sutton et al. (2021).
