>> Dear Ed,
>>  Nice work!
>>  You are completely right  that Meandrina is a particularly 
>> strong and predictable bleacher, but this is long known.  That is why 
>> my parents used it to experimentally determine the physiological, 
>> cellular, and biochemical  effects of bleaching on corals 50 years 
>> go. Since those days we have noticed it to undergo regular seasonal 
>> paling in warm seasons. This, like so much else,  has been ignored by 
>> the current generation of reef  "scientists" who do not know or 
>> respect the old knowledge. so that  they can "discover" it.
>>  For 15 years now we've been able to predict when, where, and 
>> how bad bleaching will be in almost all cases worldwide  from 
>> satellite data alone, before it can be seen in the field, using our 
>> HotSpot method (Goreau, 1989, Goreau et al. 1991, Goreau &Hayes, 
>> 1994, and much more).
>>  The Southeast  Florida area had  a well developed HotSpot 
>> this year, and Dan Clark noticed marked bleaching underway in Broward 
>> County over  a month ago, coincident with your observations. This 
>> HotSpot was completely dissipated by the reduced sunshine and strong 
>> vertical mixing that accompanied the hurricane, so we are predicting 
>> rapid recovery except for Palythoa, which will linger, as usual.
>>  Best wishes,
>>  Tom
