FDEP is making arrangement to have water samples collected inside and outside
of the Mississippi River Plume (as defined through satellite imagery) and has
collected samples immediately south of the dispersal area.  The results of
the HAB counts for the samples south of the dispersal area are available
through FMRI's red tide website (no HABs present; most recent samples July
29), additional analyses are being performed and will be reported through the
web.  Two drifter buoys (Argo tracked) were deployed on July 29 and 30th, the
position and path data are in the first Piney Point Report of satellite
imagery interpretation available at http://imars.marine.usf.edu/ updates will
be posted to the web.  The latest position of the buoy travelling around
south Florida is: 2003-08-07 11:50:10 (GMT) lat. 24.496, long. 279.369.

Re: Algal bloom supplemental:

Without intensive sampling in and out of the water and south of the 
dispersal site, one will never know what the components of the 
elevated radiance are.  We believe that the water was seen Tuesday 
off of Sebastian Inlet (27°30'N Lat) along the east coast of Florida.

I had previously responded to Stumpf:

The Mississippi River water passed through the DEP/EPA dispersal area 
and produced the dominant signal in the MODIS imagery. However, east 
of the Mississippi River water (see enclosed image from Friday) there 
are areas where the chlorophyll +CDOM readings are elevated that 
appear to be unrelated to the Mississippi River water. One of the 
reasons we wanted DEP, EPA, and NOAA to put surface drifting buoys in 
the Piney Point water was to be able to track and hopefully 
differentiate  the different water masses. Do you have access to 
surface drifting buoys that we may use to do this?"
