Temperature regimes and Coral response parameters of the artificial upwelling experiment

The following treatments were applied over a period of 3 weeks: (i) control at 28°C (ii) heat at 31°C, (iii) heat at 31°C deep water from 50 m depth, and (iv) heat at 31°C deep water from 100 m depth.

Artificial upwelling was simulated over a period of 25 min on a daily basis resulting in a reduction of temperature for 2 h per day. A total of 4 data sets are available: 2 data sets comprise the coral response parameters (i) zooxanthellae densities, chlorophyll-a concentration and (ii) net photosynthetic rates of each replicate, and the other 2 data sets include the temperature data measured throughout the experiment (iii) in all treatments and (iv) in the artificial upwelling treatment only.
