|AN AUTONOMOUS INSTRUMENTATION PLATFORM IN THE ST. JOHNS RIVER, FLORIDA|
|The St. Johns River in northeast Florida has historically been plagued with fish kills and fish with lesions. We have begun a project to determine the relationships among water/sediment quality variables and the presence of Pfiesteria-like organisms (PLOs) and fish disease events in the Lower St. Johns River basin area.|
Seven fixed sites are sampled 3 times per year. Water column and sediment samples are analyzed for various physical, chemical, and biological parameters. However, the natural variability and multiple anthropogenic influences within this ecosystem produces an array of acute stressors which may remain undetected. To establish the extent of daily temporal variability, a need exists for continuous in situ monitoring.
One of the stations has a floating platform with continuously recording instrumentation. A datalogger/control module provides control of sampling events as well as data storage and transmission via cell phone or GOES-satellite. Flow-through instrumentation samples water for relative fluorescence, nutirent, and physical/chemical parameters. A volumetric water sampler obtains samples for analyses and verification. A meteorological package, PAR sensors and an underwater current meter are also included on this monitoring platform.
