[Coral-List] Cold Water Bleaching

[Alan E Strong]

Hi James,

This is a more recent paper....for those interested.

Hoegh-Guldberg, Ove, Maoz Fine, William Skirving, Ron Johnstone, Sophie 
Dove, and Alan Strong (2005). Coral bleaching following wintry weather. 
Limnol. Oceanogr. 50: 265-271

Cheers,
Al
