A small hand- held unit is also available for use on small boats, docks, piers, and in laboratory tanks. The processor and software automatically identifies plankton based on a training set of hand-classified images obtained from archives or collected during the beginning of a field study. The VPR system allows for rapid and accurate assessment of the plankton community in freshwater and marine environments. Since the data are in digital form, they may be easily incorporated into existing data bases for statistical analysis. Paged plots are produced as requested for time dependent variables, correlation plots, 2D distributional plots, and 3D volume rendering.
Programmable video sampling protocol allows unattended sampling for months.
Required for moored VPR system.
