recently developed TRV/ water color spectrometer. These data indicate 

 that, in general, the reflectances are separable on a species basis and 

 are different from sea water reflectance. The natural phenomenon of 

 bioluminescence which is stimulated in ubiquitous marine organisms by 

 the movement of fish schools appears to offer a promising solution to 

 the problem of locating and possible identifying and quantifying fish 

 schools at night. In recent months, we have used an airborne image 

 intens if ier/televis ion system at altitudes of 5,000 feet to detect 

 fish-stimulated bioluminescence, the intensity of which was far below 

 the threshold of the human eye. Therefore, we are interested not only 

 in the physical, chemical and biological factors which affect the color 

 of the ocean, but also the effect that these factors have on the production 

 and transmission of light within the sea.
