As described above in these results of the measurements it is considered that the radiance distribution in the near-surface layer of the sea depends considerably on the radiance distribution of the sky. Accordingly the authors attempt now to improve the instrument capable of measuring the radiance distribution in the underwater and the sky at the same time automatically and if this new instrument be accomplished the authors will study these detailed phehomena described above.
Sasaki et al. (1962) studied this question.
