Abstract:
Response of Fucus photosynthesis (oxygen production) to light intensity (PI-curve) assessed at 19.5°C and at 2 pH levels (8.2 and 7.75) for an irradiation range between 0 and 800 µmol cm-2 sec-1. The oxygen gradient across the diffusuve boundary layer was measured using microsensors and used to calculate the oxygen flux and deduce the oxygen production (nmol cm-2 sec-1).
