Look at this paper:
Kobluk, D.R., and M.A. Lysenko. 1994. "Ring" bleaching in southern
Caribbean Agaricia agaricites during rapid water cooling. Bulletin of
Marine Science 54(1): 142-150.
Would be interesting to know where you are seeing this, and whether any
upwelling or cooled water might be associated with it.
"Ring" shaped bleached areas on Acropora palmata might be caused by
damselfish, see Fig. 39 in:
Williams, D.E., M.W. Miller, and K.L. Kramer. 2006. Demographic
monitoring protocols for threatened Caribbean Acropora spp. corals. NOAA

> I have recently been documenting a strange appearence on coral species in the Caribbean. Particularly on acropora sp, but also on some others....small rings of what looks like bleaching (not dead polyps, and not patches) that are approximately 2-3cm in diameter. Does anyone have any suggestions as to what or why this is?
