As the world's largest reservoir of exchangeable carbon on millennial timescales, the oceans play a dominant role in global change. Indeed, the oceans currently act as a major sink for anthropogenic carbon (1), partially moderating increases in atmospheric CO_2 at the expense of a more acidic ocean. One of the great challenges for the next century is understanding how this shift in seawater chemistry will affect marine systems. Serving as a vivid microcosm for the ocean as whole, coral reefs display the beauty, diversity, and complexity of the ocean, while also exhibiting the ocean's sensitivity to environmental perturbations.
