A video plankton recorder (VPR) is towed underwater video microscope system, which photographs small to fine-scale structure of plankton, from 50 micrometers and up to a few centimeters in size. A VPR consists of five general components: cameras (with magnifying optics), strobe, additive sensor and flight control, underwater platform and interface software for plankton identification.
