The diffuse attenuation coefficient, K, was plotted against 

 the water reflectance, Rtj/D ^^^ ^ definite correlation was obtained 

 between the two properties with the clearer (low attenuation co- 

 efficient) waters having generally low reflectance values and the 

 turbid waters (high attenuation coefficient) generally showed higher 

 reflectances. Figure 1 shows the defining relationships for K and 

 ^U/D- Figure 2 shows the relationship between the two properties 

 and, additionally, shows that a correlation existed between these 

 two parameters and the water color as subjectively determined by 

 two observers.
