Answer:
The levels of carbon are expected to_increase___ of our oceans
Explanation:
As humans activities increase the levels of carbon dioxide in the atmosphere so do the ocean levels of carbon increase. This is because of the fact that gases from the atmosphere dissolve in and out of the oceans at the interphase between the atmosphere and hydrosphere. 
The more carbon dioxide in the atmosphere, the more the gas dissolves in the oceans. This is why more corals are bleaching around the world. The dissolved carbon dioxide is lowering the pH of the ocean waters because of the formation of more carbonic acid.
