Absorption of light in water

Water exhibits much higher absorption of photons than air at some wavelengths of light. This can be seen in the graph below. Increasing the depth of the water increases the absorption, which can be modeled by the absorption equation I(x)=I(xo)*exp(α(xxo)) where α is the absorption coefficient for water at the wavelength of interest and I(x) and I(xo) are the intensities at the final and starting locations, respectively.
