Hello Saumya Silori

Under high light environment phytoplankton protect their photosystems from getting bleached by employing the non-photo-chemical quenching process which measurably suppresses the fluorescent emissions. Under such circumstances, it is possible that the fluorescence data will be highly underestimated within the highly illuminated depth of the water column within the subsurface layers and thus the estimation of euphotic depth (PHOTIC ZONE) might get misconstrued.

Abhishek Mukherjee Thank You.

Isabel Seguro Thanks for the reference.

Have a look at our paper, "Resolving the Euphotic Zone," Deep-Sea Research I, vol. 83, pp. 45-50. We propose that the biological compensation depth is roughly equivalent to the depth of the base of the fluorescence maximum.

Thank You so much. This was really helpful. John Marra

You're welcome!
