Figure S5. 1st order Taylor decomposition of the change in POC flux over the 21st century, evaluated at the 100 m depth horizon. Components of the a) total change in POC flux at 100 m (also shown in Figure 3a) were separated into changes due to b) change in NPP, and c) change in e-ratio, plus d) the residual of the decomposition. These results match those of Laufkötter et al. (2016), following their equation 18 (reproduced below) and shown in their Figure 5. The 100 m Taylor decomposition shown here can be compared with the MLDmax decomposition presented in the main text (equation 2 and Figure 6).
\begin{equation} \frac{{\partial\text{POCflux}}_{100m}}{\partial t}=\left(\frac{\partial\text{NPP}}{\partial t}\times eratio\right)_{100m}+\ \left(\frac{\partial eratio}{\partial t}\times NPP\right)_{100m}+Residual\nonumber \\ \end{equation}
