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...
Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...
