Scientific echosounder

A scientific echosounder is a device which uses sonar technology for the measurement of underwater physical and biological components—this device is also known as scientific sonar. Applications include bathymetry, substrate classification, studies of aquatic vegetation, fish, and plankton, and differentation of water masses.

Applications include bathymetry, substrate classification, studies of aquatic vegetation, fish, and plankton, and differentation of water masses. Scientific echosounder equipment is built to exacting standards and tested to be stable and reliable in the transmission and receiving of sound energy under the water. Recent advances have led to the development of the digital scientific echosounder, further enhancing the reliability and precision with which these systems operate. Modern scientific echosounders are reliable, portable, and relatively easy to use. Collected acoustic data is 'stamped' with geographic information for precise positional information (coordinates and time). This enables analysis and incorporation of the results into a Geographic Information System (GIS) for further analysis, correlation with other variables, mapping, and display.
