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?

Ocean acidification
Ocean acidification is a process that refers to the ongoing decrease in the pH levels of the Earth's oceans. According to the National Oceanic and Atmospheric Administration (NOAA), ocean acidification is caused by the rise in (CO2)into the atmosphere, which dissolves in seawater and forms carbonic acid. This process can lead to the acidification of the ocean, which can have negative impacts on marine life. Such as shellfish to build and maintain their shells and skeletons or coral bleaching. Additionally, ocean acidification can disrupt the food web and alter marine ecosystems, leading to potentially significant economic and environmental consequences.

With the ocean's acidification levels rising are there long-term effects we can see that we could reverse? According to Smithsonian's ocean research articles, the main source of CO2 in the ocean is coming from gas particles in the air produced by motor vehicles and factories. Over the last 200 years, carbon dioxide levels have risen 30 percent when measured by scientists. The excess acid in the water causes the decomposition of shells, reefs, and even fish living in this ecosystem. If enough carbon dioxide gets into the ocean we will be seeing irreversible changes to our environment, and the food we get from the ocean.
