Corals and climate change

Using two Caribbean coral species as its study subjects, Montastraea faveolata (mountainous star coral) and Porites furcata (finger coral), the research team will study how the world’s increasingly acidic oceans (caused by increasing atmospheric carbon dioxide) affect these corals when accompanied with increasing ocean temperatures as well.

“I was interested in stressing corals at differing levels of carbon dioxide and temperatures much like they would experience in the next 50 to 100 years to see if skeletal development is affected,” said Dr. Chris Langdon, one of the lab’s creators and the scientist who developed a similar lab at the University of Hawaii studying corals at varying carbon dioxide changes alone.

Dr. Andrew Baker, co-creator and also a Rosenstiel School faculty, has spent much of his career looking at climate change impacts on corals and has geared his perspective towards understanding whether corals can adapt to any of these changes. “It’s clear that corals of the future will see much warmer, more acidic oceans than we have now,” Baker said. “By mimicking these same changes in the laboratory we get a much clearer idea of how these corals will respond.”
