Fig. 3: Schematic presentation of the mechanisms driving the reduction in the air-sea CO2 flux density in (a) the North Pacific CO2 sink and (b) the Tropical Pacific CO2 source regions.

From: Decrease in air-sea CO2 fluxes caused by persistent marine heatwaves

Fig. 3

Red color indicates the thermal effect on the air-sea CO2 flux density, the blue color is linked to impacts related to circulations changes associated with PMHWs such as anomalous horizontal and vertical advection. The gray color represents the normal conditions. See text for more details.
