Acid Horizon

Climate change is changing the chemistry of the Earth's oceans. As man-made carbon dioxide causes global warming, it's also filtering down into the seas, causing Ocean Acidification. Ocean Acidification has caused mass extinctions in the Earth's past, and could destroy the largest habitat on Earth - the deep sea. Dr. Erik Cordes believes that Lophelia -- a species of deep sea coral -- is adapting to acidification and may hold secrets to survival in an acidic future. Erik embarks upon a voyage to the bottom of the Gulf of Mexico to collect valuable Lophelia samples. For the sake of future generations, Erik confronts danger on the Research Vessel Atlantis and diving in the Alvin Submersible. He's getting closer to finding the 'Supercoral'. . . But is he too late to make a difference?
