A new instrument for measuring the underwater spectral radiance distribution has been built. This instrument, an electro-optic radiance distribution camera system (RADS), allows a complete spectral radiance distribution to be measured in a short period of time and the reduction of these data to absolute radiometric values as a routine procedure. Data taken with the RADS system at various depths will be presented. These data will be reduced to obtain various apparent optical properties such as scalar irradiance, vector irradiance, and average cosine. Also, the radiance attenuation coefficient will be discussed as derived from the radiance distribution data.
