 The Tara Pacific Expedition, 2016 to 2018, investigated the impact of climate change on two species of coral, porites and diploastria. Both species showed increased aragonite saturation states at higher temperatures, but porites also increased its aragonite saturation state at lower temperatures. This suggests that porites may be better able to cope with rising temperatures than diploastria. This article was authored by Marine Kinesi, Eric Duvile, Paolo Montagna, and others.
