(a) Integrated Chl 𝑎 (∑′Chl𝑎, mg m⁻²) not including the real DCM as a function of that including it (∑Chl 𝑎), with the solid line showing the significant relationships (𝑟=0.99, 𝑃<0.01, 𝑛=38). (b) The underestimated ∑Chl 𝑎 (%) when missing the real DCM as a function of its depth (m), with the lines indicating the significant relationship (solid line, 𝑟=−0.63, 𝑃<0.05, 𝑛=20; dashed line, 𝑟=0.68, 𝑃<0.01, 𝑛=18).
