The Oceans play a huge part in the carbon cycle, and the Earth's oceans act as a carbon sink. As the carbon Dioxide levels in the atmosphere increase, as they have been doing for a few decades especially due to anthropogenic (human made) greenhouse gas emissions from the combustion of fossil fuel reserves, the volume of carbon dioxide that the ocean has been absorbing has increased. When the concentration of carbon dioxide increases within a liquid, the pH decreases therefore becomes more acidic. As the carbon dioxide concentration has risen in the Earth's atmosphere, some sources have calculated that the pH of the oceans has decreased (become more acidic) from pH 8.179 to 8.104 (a change of - 0.075). Models have predicted that by the year 2100, the ocean's pH could change to around pH 7.824, a reduction of - 0.355 since the pre-industrial age in the 1700's. *Note that the pH scale is a logarithmic scale, and pH 7 is neutral. This change in pH in the World's oceans could have huge negative effects on the delicate ecological systems, in particular oceanic calcifying organisms. For example, evidence suggests that one of the Natural Wonders of the World; The Great Barrier Reef could be at risk from this oceanic acidification.

The moon has a greater effect than the sun on the earths oceans.
uuu
Changing the pH the chemical composition is changed; as a consequence the the refractive index is influenced.
it has been washed into the oceans as the continental crust has eroded.

97.5% of Earth's water is found in the oceans. 2.5% is found in freshwater lakes.
The gravitational forces of the Sun and Moon, effect the earths oceans by forming tides.
