Learn about research into how some coral reefs survive ocean acidification in this NOVA Next article. Environmental changes, such as rising temperatures and ocean acidification, threaten coral reefs around the world. However, some reefs are thriving despite extreme conditions. Some areas of coral reefs, such as those found off the coast of Palau's Rock Islands, seem to be natural refugia and may be less vulnerable to climate change. Researchers and conservationists are interested in learning about how these reefs are surviving seemingly hostile conditions. Explore the focus on Palau's refugia with the "Seeking Refugia" and "Picking Winners" sections (pps. 7-13) of the article. This resource is part of the NOVA Next Collection.
