organic carbon Fossil Fuels organic carbon Weve talked about 4
pools so far. Now we are introducing the ocean pool. Where is the
carbon in the ocean pool?
Oceans contain 50 times more carbon dioxide than the atmosphere!
Carbon is located in carbon dioxide (CO2) in the water. Carbon is
located in calcium carbonate (CaCO3) in coral reefs and animal
shells. Ocean organic carbon Why is ocean acidification
harmful?
Increased levels of CO2 turn the ocean acidic. Acidic oceans mean
that coral reefs cannot take carbon from the water to build their
bodies. Acidic water also means that animals with shells (krill,
crabs, shrimp, etc) cannot make their shells, which impacts the
entire marine ecosystem. This graph is part of the 2013 National
Climate Assessment, which can be found at This graph shows that as
atmospheric CO2 levels go up (red line), oceanic CO2 levels go up
(dark blue line), and ocean pH goes down (light blue line). How
does climate change affect the oceans?
Melting ice caps cause water levels to rise Increased ocean
temperatures affect ecosystems and living things in the oceans
Increase in carbon is absorbed by the water Ocean organic carbon
How do unhealthy oceans impact people?
Rising water levels impact people who live near oceans and on
islands. Acidic water and temperature rise harms animals, which
hurts the fishing industry. Rising ocean temperatures lead to more
extreme weather events (hurricanes, heavy precipitation, etc).

no oceans?
