Knowing the optical character on the surface layer in the ocean is very important factor as something like the index of the vertical migration of plankton, and fish migration and swimming layer which is the occasion of it. The author has examined the instrument which measured the optical characters, namely, underwater irradiance, radiance and turbidity in the sea. This radiance-irradiance meter is a telerecording instrument .with a photomultiplier tube which gives a logarithmic responce and the anode current is kept constant by verying automatically the high voltage which is used as a measure of the light flux. Seven interference filters and three polaroid filters are automatically changed, and an electrical operation selects one of seven and three positions. The turbidity meter is set four interference filters which electrically are operated in accordance with the object. The maximum sensitivity of these filters is the same sensitivity as the radiance-irradiance meter is.
