We then start to move up the salinity scale and things start to change. In the 4% salinity column, stratification begins to disappear... There is no longer the green top growth and the water changes to a mucky brown color. This could show that the addition of salinity, changes the growth patterns and the wavelength of light used for organisms to grow. At 8%, the water begins to clear and a firm black/brown color begins to develop between the aquatic layer and the sediment. This growth still uses light but not much it seems... We finally arrive at the 12% salinity, we still have that dark brown/ black color of organisms under the aquatic layer but its minimal. It seems we have extremely limited the growth nutrients but as always... Life finds a way.
