Pocillopora damicornis adult pCO2 x temperature experiment. This project was carried out with collaborator Dr. Hollie Putnam. We have not published the findings yet, but I can tell you this: a 15-day exposure to a pCO2 of 850 ppm did virtually nothing to adult Pocillopora damicornis samples! The question is: does this experiment, all by itself, mean that OA is not a big problem or is it, perhaps, that these corals were from upwelling environments and so already have special adaptations for all manner of environmental change? Or maybe we just didn’t exposed them to high pCO2 for long enough?
