Grace Klinges just finished a diving expedition off the Coast of Papua New Guinea where a natural CO2 seep acidifies the reef and changes the ecosystem so much that fish avoid the area. Less than 60meters away the ocean chemistry returns to normal conditions and there is an incredible amount of reef diversity shows by colorful corals. Using this relatively small area that mimics future ocean acidification scenarios, Grace is able to examine which organisms are the most robust to the rapidly changing ocean chemistry and hopefully find out how they interact and save our coral ecosystems!
