An inexpensive way of obtaining reliable measures of marine environmental conditions in the water column.
The ASL Water Column Profiler™ offers a new, inexpensive way of obtaining reliable measures of marine environmental conditions in the water column. The Water Column Profiler™ can monitor the presence and location of zooplankton within the water column by measuring acoustic backscatter returns with ultrasonic frequencies. Other sonar targets realizable from the sonar backscatter data include fish and sediments.
Using onboard data storage, the Water Column Profiler™ can collect data continuously for periods of up to several months and can be operated in a upward looking orientation from the sea-bed or a subsurface mooring or in a downward looking mode from a surface buoy.
