	Ocean Acidification Impacts Coral Reefs The ocean is absorbing large amounts of carbon dioxide—a natural process. However, as carbon dioxide enters the ocean, it reacts with water to form acid. Subsequent chemical reactions that try to maintain a normal pH level in the ocean end up reducing the amount of calcium carbonate—a component in the skeletons of many organisms such as corals, lobsters, clams, and pteropods. Without calcium carbonate, these organisms cannot properly grown and reproduce. In this animation, we show model data of how the availability of calcium ca (more...)
	Humans Impact the Ocean Human activities, both knowingly and unknowingly, affect the ocean. A team of 19 scientists, including one from NOAA, undertook the task of mapping how humans have impacted the ocean over time. This animation takes a tour of this marine impact map and identifies some of the sources of negative impacts on the ocean.
	Coral Science from Outer Space to Inner Space Coral bleaching is a threat to reefs around the world. This production, created for the Science on a Sphere, details the science behind why corals bleach, what NOAA is doing to monitor and prevent coral bleaching, and also what you can do to help. Audio is included.
