Description:The conventional use of optically determined 1% of surface photosynthetically available radiation (PAR) depth (Z 1%PAR, λ = 400–700 nm) as a metric for the euphotic zone depth (Z eu) has been a matter of debate for several decades because of frequent inconsistencies with the base of euphotic zone determined biologically, that is, the compensation depth (Z c). In this study, we attempt to reconcile between optical and biological determinants of the euphotic zone through the use of a large data set of coincidental profiles of downwelling irradiance and primary production. These measurements cover open ocean waters in the tropics, subtropics, temperate regions, and from two time-series stations, the Hawaii
