Calcification is not the Achilles' heel of cold-water corals in an acidifying ocean
Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO 2 seep research has shown adverse effects on many coral species, although a few are resilient. There are concerns that cold-water corals are even more vulnerable as they live in areas where aragonite satur...

We transplanted D. dianthus to 350 m depth (pH T 8.02; pCO 2 448 μatm, Ω ara 2.58) and to a 3 m depth CO 2 seep in oligotrophic waters (pH T 7.35; pCO 2 2879 μatm, Ω ara 0.76) and found that the transplants calcified at the same rates regardless of the pCO 2 confirming their resilience to acidification, but at significantly lower rates than corals that were fed in aquaria.

Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO 2 seep research has shown adverse effects on many coral species, although a few are resilient. There are concerns that cold-water corals are even more vulnerable as they live in areas where aragonite saturation (Ω ara ) is lower than in the tropics and is falling rapidly due to CO 2 emissions. Here, we provide laboratory evidence that net (gross calcification minus dissolution) and gross calcification rates of three common cold-water corals, Caryophyllia smithii, Dendrophyllia cornigera, and Desmophyllum dianthus, are not affected by pCO 2 levels expected for 2100 (pCO 2 1058 μatm, Ω ara 1.29), and nor are the rates of skeletal dissolution in D. dianthus. We transplanted D. dianthus to 350 m depth (pH T 8.02; pCO 2 448 μatm, Ω ara 2.58) and to a 3 m depth CO 2 seep in oligotrophic waters (pH T 7.35; pCO 2 2879 μatm, Ω ara 0.76) and found that the transplants calcified at the same rates regardless of the pCO 2 confirming their resilience to acidification, but at significantly lower rates than corals that were fed in aquaria.
