FIELD: physics.
SUBSTANCE: method involves installation of buoy stations united by radio channel into common measuring network on water area subject to monitoring. Stations continuously measure the density of objects of the field by hydroacoustic method, process the obtained data by echo-integration and transmit the results to the base station. Base station automatically generates, by geostatic interpolation, a visual representation of the monitoring results in the form of an animated map of the field objects which reflects the dynamics of their spatial distribution and migrations. Card is accessed via a local network or the Internet.
EFFECT: invention makes it possible to observe field conditions and to forecast direction of movements and dynamics of biomass of field objects on the monitored water area.
