Thanks again, Scubaman for following up on this. To me, it still sounds like stoney coral bleaching caused by a combination of warming sea temperatures and high nutrient levels in the water. I would like to see them identify or name the pathogen responsible, but they may not know precisely what this is. Several years ago coral reefs in the Indo-Pacific were being attacked and decimated by the Crown of Thorns Starfish, but that's obviously not the case here. I'll have to dig into this further to see what I can find out. I hope they can get this turned around soon.
