Studied since the 90s, the concept of ocean acidification is fairly recent. The CO2 released by human activities acidifies the oceans and impacts the growth of corals as well as calcified organisms.
On the outskirts of Shikine Island, Japan, Taranauts scientists were able to dive on a naturally acidified site due to underwater volcanic CO2 emissions. The data collected should therefore help them better understand what is playing under the surface.
