Figure 4

Seasonal air-sea CO₂ fluxes (mol C m⁻² year⁻¹) calculated using the wind speed parameterization of Ho et al.³⁶. Note that the actual minimum and maximum values are approximately − 30 and 39 mol C m⁻² year⁻¹, respectively. Positive values (red symbols) indicate an oceanic CO₂ source to the atmosphere and negative values (blue symbols) indicate oceanic uptake of CO₂. The solid black line represents the 200 m bathymetry contour.
