Fig. 4: Climatological dependence of chlorophyll on nitracline and EUC core depths.
From: Seasonal productivity of the equatorial Atlantic shaped by distinct wind-driven processes
a–f, Shown are scatter plots of 20 °C isotherm (or nitracline) depth, \({D}_{20^\circ\mathrm{C}}\) (a,b), EUC core depth, \({D}_{\mathrm{EUC}}\) (c,d), and their difference, \({{D}_{\mathrm{EUC}}-D}_{20^\circ\mathrm{C}}\) (e,f), versus chlorophyll for the climatological seasonal cycle at 0°, 10° W (a,c,e) and 0°, 23° W (b,d,f). Chlorophyll is averaged in the box 1° S–1° N, 30° W–0°. Also included are linear regression lines and the corresponding Pearson correlation coefficient, \(r\).
