Ek_max: Maximum photoadaptation parameter

Ek_max is the maximum photoadaptation parameter. Ek_max reflects the amount of photosynthesis a plant can undergo at a certain light level. Phytoplankton are light limited if there is not enough light available for them to grow at their maximum rate. Lower Ek_max values mean that phytoplankton approach their maximum levels of photosynthesis at lower light levels.
