    <p>Net photosynthesis (J, mol m<sup>-2</sup> s<sup>-1</sup>) of <i>P</i>. <i>oceanica</i> was measured on leaves from REF (dots, n = 3) and CO2-R (triangles, n = 3) in relation to manipulated seawater pH<sub>T</sub> (regression analysis, adjusted R<sup>2</sup> = 0.50, p = 9.93e-06, no outliers, residuals normally distributed).</p

    pH profiles in close vicinity of the <i>Posidonia oceanica</i> leaves (originating from REF) when subjected to seawater acidification in the laboratory experiment.

    <p>pH<sub>T</sub> profiles (averages ± s.d.) were measured on the convex side of <i>P</i>. <i>oceanica</i> leaves at seawater pH<sub>T</sub> 7.6 (triangle), 6.6 (square) and 5.5 (circle). Measurements started from the leaf surface (distance = 0 μm), and were performed in both light (black, n = 2–3) and dark (white, n = 1) conditions.</p
