[Coral-List] GCBE3 -- potential biodiversity disaster

I think it would benefit a great many of us if incidences of coral
bleaching are reported to the List, and/or that anybody tracking the
incidences also post their results to the list. This not only helps
those involved in bleach forecasting, but helps environmental managers
and policy makers know the global extent and how their regions fit into
the global picture.
ALSO, I think it is important that people who are expecting
bleaching at their locations, due to historical bleaching incidences,
current bleaching forecasts, or due to incidences of physical factors
usually being conducive to bleaching, report incidences of *NO*
bleaching. This helps to improve the bleaching ecoforecasts, and might
provide an indication of a more resilient region or area (worth
researching in the future). It's also important to record or report as
much as you can on the values of environmental parameters as you can,
e.g., not only sea temperature, but if possible light (or "sunny" or
"cloudy"), currents, turbidity, winds (e.g., "doldrums" or "stormy" if
no actual wind speeds), salinity, etc.
Finally, if you are in a position to see the progress of a bleaching
event from no bleaching to mass bleaching, knowing which species bleach
first, and at what sea temperature (and other parameters, if possible)
may be useful in the future for MPA planning. If you find that corals
near mangroves or seagrasses are not bleaching, while other areas are,
that's an important piece of information for MPA planning. Any
follow-up records on changes to the ecosystems are extremely valuable
(e.g., invasion of particular species, mass migration of species out of
the area, epizootics, etc.). If you can record the event in
photographs, that will be very helpful in the future, too.
