[Coral-List] Request for field observations: Flower Garden Banks National Marine Sanctuary

    Of the many sites we monitor for conditions theoretically conducive
to mass coral bleaching (e.g., high sea temperature, low winds, and high
irradiance, through in situ or satellite data) at
http://ecoforecast.coral.noaa.gov, four sites are in the Flower Garden
Banks National Marine Sanctuary in the northern Gulf of Mexico.  Since a
whole armada of various government, industry and private vessels have
been in that region, due to the Deepwater Horizon Oil Spill, we here at
AOML/CHAMP are wondering if there have been any observations of
bleaching at the following four virtual station sites, where conditions
appear to be possibly conducive to such an event:

    Sonnier Banks  (28.353 ° latitude, -92.483 ° longitude)
    West Flower Garden Bank  (27.883 ° latitude, -93.84 ° longitude)
    East Flower Garden Bank  (27.927 ° latitude, -93.626 ° longitude)
    Stetson Bank  (28.179 ° latitude, -94.312 ° longitude)

    Feedback helps us to fine-tune our forecasting and modeling efforts,
so any direct observations  as to species, dates, environmental
conditions, location, etc. would be helpful.  An example report is shown
at the bottom, and please note that we consider these reports as
research mode only, not operational.

Ecological Forecast: 'Mass bleaching of hard corals'
Station/Site: East Flower Garden Bank 'virtual monitoring site', FGB National Marine Sanctuary (EBFG1)
Forecast/diagnostic generated on 7 Aug 2010  10:29:56 p.m.

Forecast as of Friday, 2010-Aug-06 (Day 218)

Model Rule:
    'Mass coral bleaching (high SST + high light + low wind)'

    Stimulus/Response Index (S/RI) = 51, because:
            Photosynthetically Active Radiation at ocean surface (Parsurf) was High (1718.697) during period Mid Day
            hourly average wind speed (Windsp) was Low (5.26) during period All Day
            REMSS 'MISST' blended microwave/infrared SST (Sst) was High (31.123) during period All Day

Cumulative Stimulus/Response Index: 51
