Figure S4. Depth profiles of the climatological mean POC flux profiles from the beginning (2005-2024) and end (2081-2100) of the 21st century simulation at each of the four sites shown in map view in Figure 2c and highlighted in Figures 5 and 7 in the main text. Dashed lines indicate the climatological mean MLDmax at the beginning and end of the century. Note the variation in both x and y axis scales among the four subplots.
