Hi Ron

We have something that may be able to help you - we've developed colour 
charts to monitor bleaching and they include a thermometer.  The CoralWatch 
Coral Health Chart consists of a series of coloured areas representing the 
most common coral colours.  Within each area, the brightness of the colours 
is varied systematically to represent different stages of bleaching and 
recovery.  Within species, each colour corresponds to a concentration of 
symbiotic dinoflagellate.  In the field, you simply compare the colour of a 
coral with the colours on the chart and record matching codes.

If you would like me to send you a chart (free of charge) please let me know.

Cheers Kylie
