Table 1. Coral surface area, volume, and skeletal density of live and dead coral fragments as well as polyp counts of live corals.

Surface area (in mm2) and volume (in mm3) are calculated from CT scans and given for live white and orange coral fragments as average of all replicates (n = 4 white as well as orange corals at Leksa on-reef and Sula, and n = 3 white as well as orange corals at Leksa off-reef) ± standard deviation at the three deployment locations.
