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}
