Coral colony bleaching scores were determined visually on a 5-point scale from photographs with 1 being fully pigmented and 5 being fully bleached as in McClanahan 2004.

Photosynthetic and respiration rates were calculated from volumetric oxygen production and consumption rates (i.e., micromole oxygen per minute per liter: µmol O2 L-1 min-1) by multiplying the oxygen concentration changes and volume of water in each chamber (chamber volume – coral volume in liters) and accounting for background oxygen flux rates by subtracting the rate of the corresponding seawater-only control chamber. Photosynthesis-irradiance (PI) curves were generated by curve fitting to the Platt model (Platt, Gallegos, and Harrison 1980) in order to extract alpha, Ik, and Pmax. Respiration was calculated from the dark period following the PI curve maximum step. Gross photosynthetic rates were determined by subtracting the oxygen consumption rates from oxygen production for each fragment.

Chlorophyll content was calculated from the equations in (Jeffrey and Humphrey 1975) for dinoflagellates in 100% acetone, correcting for the 0.6 centimeters path length of the 96-well quartz plate:
Chl a = (11.43(A663 - A750/PL) – 0.64(A630 – A750/PL))/(mL homogenate)

The difference between the ash weight and the dry weight was calculated to determine the AFDW of each fragment.

The difference between initial and final readings of antioxidant capacity was used to calculate TAC in micromoles (µM) against the uric acid standard curve. Uric acid equivalents were converted to copper reducing equivalents (CRE).

BCO-DMO processing description:
- Converted dates to ISO date format (yyyy-mm-dd);
- Adjusted field/parameter names to comply with BCO-DMO naming conventions;
- Added the "Site", "Pair", "Bleach", "Latitude", and "Longitude" columns from the "CollectionSummary" data file to the "SummaryData" file;
- Changed longitude from degrees West (positive values) to degrees East (negative values);
- Added a conventional header with dataset name, PI names, version date.
