Abstract
Two common reef-building corals, Montipora capitata and Pocillopora acuta, were collected from six sites in Kāne'ohe Bay, O'ahu, Hawai'i. Fragments were allowed to acclimate in experimental tanks for two weeks prior to exposure to one of the following four treatments: Ambient Temperature Ambient pCO2 (ATAC), Ambient Temperature High pCO2 (ATHC), High Temperature Ambient pCO2 (HTAC), and High Temperature High pCO2 (HTHC). The treatment period lasted for a two month period, starting on September 22nd, 2018 and lasting through November 17th, 2018. Following the stress period, coral fragments were exposed to a two-month recovery period in ambient conditions. Throughout the entire four-month experiment, fragments were randomly sampled from each tank and treatment for the following physiology parameters: gross photosynthesis, respiration, net photosynthesis (gross photosynthesis - respiration), photosynthesis:respiration ratio, chlorophyll concentration (pigment a and c2), symbiont and host tissue biomass, symbiont:host tissue biomass ratio, host soluble protein, host total antioxidant capacity, and endosymbiont density. Net photosynthesis, chlorophyll concentration, and symbiont tissue biomass were normalized to host surface area (cm-2) and endosymbiont density (cell-1).   For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.
