The penetration of solar radiation into natural waters is dependent on a wide range of variables, both in the atmosphere and in water, and we do not have space to demonstrate all situations. We have selected only one fixed set of environmental input parameters, and the choice of inherent optical properties has been limited to only pure water and a range of chlorophyll concentrations. However, these few simulations display a wide range of variability found in solar radiation penetrating to depth underwater. In general, as the absorption increases, the wavelength of maximum penetration shifts from the blue to the green part of the spectrum and attenuation increases.
