Dear Dr. Hendee

I am a Brazilian marine biologist who is currently involved in a coral
reef monitoring exercise in Brazil. We have been monitoring the effect
of a dredging operation on a reef. We have data on TSS, Turbidity,
temperature, salinity, dissolved oxygen and other physico-chemical
parameters, and we are also monitoring individual coral heads on a
monthly basis to spot bleaching. 

Using the data obtained before the dredging started, we attempted to
establish "safe" turbidity and TSS levels, that should not be surpassed.
We also designed a protection plan destined to avoid major damage to the
reef. The measures involved:

a) establishing "dredging exclusion zones" around the reef;
b) establishing maximum acceptable levels for both TSS and turbidity;
c) establishing tolerance levels for "natural" (ie, El Nino derived) and
"anthropogenic" bleaching (a difficult task). 

My question refers to whehter there are any data concering the
environmental levels of both TSS and turbidity thay may be correlated to
bleaching episodes (or on the other hand, "safe" levels). If you are
aware of any source that I may have access, could you please let me
know.

In addition, if you have any interest on my data I would be pleased to
share them with you.

Sincerely

Pablo Alejandro Cotsifis
Salvador - Bahia / Brazil.
