"Albright and her colleagues created a huge inflatable container that would rise from the ocean floor and trap 15,000 liters of seawater, “like submerging a bucket underwater and pulling it up,” she says. They then used a ring of air diffusers, much like those that send bubbles into aquarium tanks, to saturate the trapped water with carbon dioxide. This gas acidified the water, which Albright then pumped over a nearby patch of corals, simulating what these creatures will experience 100 years from now."
