definition: A Video Plankton Recorder consists of a single video camera and synchronized strobe that photographs a volume of water at a rate of 60 Hz. Images are transmitted to the surface via fiber-optic cable where time-code from a GPS system is added and data are archived on S-VHS videotape. The video signal is also routed through a real-time image processing system. Additional information available at "http://zooplankton.lsu.edu/vpr.htm" [Source: Louisiana State University]
