Abstract It is shown both experimentally and theoretically that the depth of the euphotic zone is related to the color of the sea defined as a color index equal to the ratio of the upwelling blue (450 nm) and green (525 nm) nadir daylight just below the sea surface. The relationship is valid for most sea waters where the albedo from the bottom is negligible near the sea surface and where the composition of suspended and dissolved matter is not largely determined either by water drainage from land or by turbidity currents. The standing stock of phytoplankton and its primary productivity within the euphotic zone can approximately be given in terms of the color of the sea. The accuracy in determining each of the above two biological quantities from color measurements at the sea surface is not satisfactory at present. This holds particularly true when the color of the sea is measured remotely by present satellite techniques.
