Abstract or Summary
  • Euphotic zone depth, z[subscript]1%, reflects the depth where photosynthetic available radiation (PAR) is 1% of its surface value. The value of z[subscript]1% is a measure of water clarity, which is an important parameter regarding ecosystems. Based on the Case-1 water assumption, z[subscript]1% can be estimated empirically from the remotely derived concentration of chlorophyll-a ([Chl]), commonly retrieved by employing band ratios of remote sensing reflectance (R[subscript]rs). Recently, a model based on water’s inherent optical properties (IOPs) has been developed to describe the vertical attenuation of visible solar radiation. Since IOPs can be nearanalytically calculated from R[subscript]rs, so too can z[subscript]1%. In this study, for measurements made over three different regions and at different seasons (z[subscript]1% were in a range of 4.3–82.0 m with [Chl] ranging from 0.07 to 49.4 mg/m³), z[subscript]1% calculated from R[subscript]rs was compared with z[subscript]1% from in situ measured PAR profiles. It is found that the z[subscript]1% values calculated via R[supscript]rs-derived IOPs are, on average, within ~14% of the measured values, and similar results were obtained for depths of 10% and 50% of surface PAR. In comparison, however, the error was ~ 33% when z[subscript]1% is calculated via R[subscript]rs-derived [Chl]. Further, the importance of deriving euphotic zone depth from satellite ocean-color remote sensing is discussed.
