Dave Ward (via Jules Craynock) reports that the large, plating Agaricia spp. in deep water (i.e., 20 m) are about 30% bleached. The Agaricids are known to be conspicuous annual 'bleachers' and the majority of this is likely sub-lethal seasonal paling (See work by our colleague Dr. William Fitt at the Univ. of Georgia).
When Dave and I dove at the end of August, these same colonies were either partially bleached or pale, so this report is not unexpected.
