Bacterial production (BP; µg C L⁻¹ d⁻¹) plotted as a function of net primary production (NPP; µg C L⁻¹ d⁻¹) showing the linear response at lower NPP and the saturating response above ∼ 40 µg C L⁻¹ d⁻¹. Error bars in gray indicate ±1 standard deviation from the mean of triplicate measurements. A Reduced Major Axis (RMA) regression line (slope = 0.097, y-intercept = −0.14, and R² = 0.48) is shown (black dashes). All data are from the upper 100 m where NPP rates were measured; dark gray points are above the 40 µg C L⁻¹ d⁻¹ threshold and were not used in the RMA regression.
