Figure 6

(a–f) Simple, linear regressions of observed vs predicted log10 NPP and GPP (mg C m−2 d−1) for OH, MH, and PH salinity zones using generalized additive models (GAM). Source data for GAM were obtained in measurements of simulated in-situ 14C-bicarbonate assimilation and ancillary properties from 1982 to 2004 (n = 723). Closed circles = log10 NPP; open circles = log10 GPP; crosses = residuals, dashed lines = simple, linear regressions of residuals vs model-fitted NPP or GPP.
