From these empirical relationships a bio-optical model of the upper layer was developed.
WebTurbidity is an optical determination of water clarity 1. Turbid water will appear cloudy, murky, or otherwise colored, affecting the physical look of the water. Suspended solids and dissolved colored material reduce water clarity by creating an opaque, hazy or muddy appearance. ... Ocean water is usually clearer than freshwater due to the ...
