Water quality monitoring programs typically rely on intrusive spot-sampling, an appraoch that excludes most of the high-frequency variability in aquatic ecosystems. To address this deficiency, many programs now incorporate continuously recording instrumentation to supplement their conventional sampling. 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, Fl. The natural variability and multiple anthropogenic influences within this ecosystem produce an array of acute stresses that require high-frequency sampling. In order to address these issues, we have deployed MARVIN, 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, nutrients, 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.
