The simulations provided here are based on the model version including a dynamic, prognostic iron cycle (Somes et al. 2021), and they use the previous formulations for nitrogen and carbon isotopes (Somes et al. 2017; Schmittner et al., 2013).

Here we provide euphotic zone results from the North Atlantic corresponding with the associated squid data locations.
