THE LIGHT OF ABSORPTION:
We took samples from the bottom and the surface in three different sites of the Pedder bay that is the marina, PC docks and the mouth of the bay. From the samples we took, we studied their absorption of light parteins according to the wavelength of the light (colour). Though there is not much of difference quantitatively, but still the sample showed remarkable parteins that differed mainly due to depth variations. These parteins will be explained with reference to the partein in the distilled waater which we used for calibrating our spectro viz.

THE DOCKS:
From the docks we collected our samples from the surface and the bottom, and after the spectroviz analyisis, the following graphs were produced.


NB: the graph of distilled water is just for reference

• from the graphs we can observe the following
  

• For the case of distilled water, the there is very little absorption of light generally, but still we see violet light is mainly absorbed thats about 0.29%of all the light. At the boundary between green and yellow light, no lifgt is absorbed at all. then we see red light being relatively more absorbed.
• From the sample in the bottom water in the docks, we see the same case whereby most of the light pass the sample unabsorbed. The violet light is stillthe most absorbed, with an increase to about 4.6% of light absorbed. the trend generally conform to the distilled water's but with relatively increase in the absorption of light.
• From the surface water sample we see something a bit more remarkable. There is a general trend whereby the rate of absorption of light decreases with the increase in the wavelength of the light. There is a significant rise in the rate of absorption of the violet light to about 1.3% compared to the distilled water.
