Therefore, water near the seashore that is more turbid (cloudy) due to particles will show a decrease in light transmission, even in shallow water. This is due to large numbers of particles brought in by river systems, and biological production by microorganisms as well as waves, tides, and other water movement picking up debris on the ocean.
