Initially the corals were taken outside on a sunny, hot day to stress them. The phi2 values began to drop quickly due to the increased temperature and light. However, towards the end of the day, the light intensity began to dwindle and the corals seemed to start recovering minimally. This may be the reason that the corals did not experience irreversible effects of the high light conditions (even though they were in these stressful conditions for 40 minutes). In addition, another data set revealed that with high light (~1100 microE) and without high temperature change the corals phi2 values did not often drop below 0.2 (direct light may not have been hitting each of the samples evenly). This confirms that the coral stress is also very dependent on the water's temperature change and further data points with increased temperatures will be recorded soon.
