Short summary
To protect from light stress, phytoplankton inhibit photosynthesis and suppress fluorescence through the process of quenching. This makes them invisible to fluorometers. Conventionally, quenching is corrected by taking maximum fluorescence yield in a surface mixed layer (MLD) and filling in the invisible proportion. This is only valid in waters where turbulence is high and phytoplankton are uniformly mixed. Here, we show that correcting from Zeu is a robust alternative to correcting from MLD
