Gates,-R.D.  Seawater temperature and sublethal coral 
	bleaching in Jamaica.  CORAL-REEFS. 1990. vol. 8, no. 4, 
	pp. 193-197.

Permanent study sites were established at 6 m, 12 m and 18 m 
on the West Fore Reef at Discovery Bay, Jamaica. Colonies of 
Montastrea annularis, Porites astreoides, Porites porites  
and Agaricia  spp. were assessed for presence and extent of 
bleached tissue at two month intervals between October 1986 
and September 1987. In 98% of all corals exhibiting a 
bleaching response, less than 25% of the colony appeared 
pale. In the remaining 2%, more than 25% of the tissue 
appeared pale. M. annularis, P. astreoides  and Agaricia  
spp. showed a significant positive correlation between the 
percent of colonies exhibiting a partial bleaching response 
and seawater temperature. There was no significant difference 
in the percentage of colonies bleached between the three 
depths. M. annularis  and Agaricia  spp. exhibited a 
significantly higher percentage of colonies bleached than P. 
astreoides  and P. porites . For M. annularis  15% of coral 
colonies studied showed 1-2 cm super(2) randomly scattered 
patches of pale tissue which remained constant throughout the 
study. The partial bleaching patterns observed in this study 
were never lethal and are considered, in part, to be a 
response to seasonal variations in seawater temperature.
