Seafloor Organisms and Changing Ocean Conditions in Antarctic
This project studies the effects of rising ocean acidification and temperatures on seafloor dwelling animals in the shallow waters of Antarctica. Carbon moves around the earth, between land, atmosphere, and water in the carbon cycle. The ocean absorbs Carbon Dioxide (CO2) from the Earth’s atmosphere. As increasing amounts of Carbon Dioxide are absorbed, the pH of the water is decreasing or becoming more acidic. This is called ocean acidification. Several marine animals, such as mussels, snails, sea urchins, and more use the naturally occurring calcium (Ca) and carbonate (CO3) in seawater to construct their shells or skeletons. As seawater becomes more acidic carbonate becomes less available, which makes it more difficult for these organisms to form their skeletal material. This negatively affects the health of the animal in many different ways.
