Absolute electron transport rates with increasing irradiance of Phaeocystis antarctica after exposure to different Fe and Mn availabilities at the end of the experiment

At the end of the experiment, electron transport rates irradiance curves were conducted applying 8 irradiances from 0 up to ~400 μmol photons m-2 s-1 for 5 min for each light level. A light sensor (ULM-500, Walz GmbH, Effeltrich, Germany) measured each light intensity (E, μmol photons m-2 s-1) emitted from the FastAct Laboratory system.
