Experimental design and measured response variables across the experiment. (a) Treatments based on the current in situ conditions (white, control) and the IPCC SSP5-8.5 scenario for temperature (12 vs. 15 °C, red), pHT (~ 7.99 vs. 7.69, total scale at in situ temperature, yellow) and Dissolved Oxygen (DO) concentration (~ 6.4 vs. 4.7 mL L−1, blue). Treatments are depicted from left to right: Control, elevated temperature, low pH, low oxygen, combined elevated temperature and low pH, combined elevated temperature and low oxygen, combined low pH and low oxygen, and combined elevated temperature, low pH and low oxygen. Water parameters for each treatment were modified in their corresponding header tank that supplied to (b) three replicated experimental aquaria, holding three coral nubbins each (c) Measured response variables and time of the analyses over the duration of the experiment: filled circles represent conducted analyses on a specific response variable at the corresponding experimental time (0, 2, 4, 6 and 9 months); blank circles indicate periods when analyses for that response variable were not conducted.
