In addition to the famous impacts of atmospheric carbon on global warming, there is an equally worrisome effect of carbon dioxide on the oceans: ocean acidification (or OA for short). Here at I2SEA we have a series of resources about OA, including Our Acidifying Ocean, which is an introductory activity and virtual lab (note: now mobile compatible!).
A student suggested that we start a conversation topic about OA, and here it is! Have you heard about Ocean Acidification? If so, are you worried about it? How do you think we can best raise awareness about it among your fellow students and the general public? Have you seen particularly good links or films about OA that you would like to share? What are you doing to address the problem?

What is Ocean Acidification
Ocean acidification is when the ocean has a reduction of pH over a period which is caused by an intake of co2 from the atmosphere. Ocean acidification affects all of the world's oceans and their sea life, even smaller bodies of water like estuaries and waterways. Ocean acidification reduces the amount of carbonate which is a very important part of seawater. With the reduced about of carbonates in the water, it makes it harder for marine animals to form their shells. For example, animals such as mollusks, corals, and some plankton. The shells and even skeletons of these animals become less and less strong and dense. Coral reefs even become weaker and more susceptible to damage from storms which causes them to have a slower recovery time.
