Module 2

Module 2 - Ocean Acidification

Ocean acidification is a much lesser known effect of increased carbon dioxide in the atmosphere. Oceans absorb up to 30% of the CO2 in the atmosphere. Once in the water, CO2 reacts with water to create carbonic acid lowering the pH of oceans and affecting shellfish, fish, and corals and the balance of their associated food webs.

There is no "quick fix" for ocean acidification; knowledge of the effects of people’s carbon footprint is essential to help minimize the ongoing problem. In this unit, we'll look at the remoteness of the Antarctic region and how it highlights how the effects of ocean acidification felt all around the world, including in unpopulated areas. With a focus on solutions, the unit will also discuss present day technologies and solutions.
