Here, we analyzed nutrient concentrations from CMIP6 under three emission scenarios: the historical period, middle-of-the-road (SSP2-4.5), and business-as-usual (SSP5-8.5) (Table ) . For the historical scenario, we confined the years to 1972 -2014 to better match the time span of the observations. The future emission scenarios were confined to the years 2015 -2100. Our primary variables of interest were marine concentrations of nitrate and phosphate ("no3" and "po4" respectively). We also analyzed sea temperature ("thetao") and salinity ("so") through time to convert the nutrient concentrations from mol m -3 to µmol kg -1 , and determine trends in nutricline densities. These variables came from consistent model variants in terms of realization, initialization, method, physics, and forcing; the "r1i1p1f1" variant was used when available. With these variables, we quantified nitracline and phosphacline depths with time.
