Critical Specifications for Acoustic Doppler Current Profiler (ADCP) Research on ecologically compatible management practices for Pacific shellfish production requires collecting physical environmental conditions in estuarine habitats, which includes tidal current velocities and turbulence. Two identical Acoustic Doppler Current Profilers (ADCPs) are required to collect high resolution current velocity profiles in shallow water, in two locations and/or two habitats simultaneously. REQUIREMENTS Condition measured Current velocity, waves, and turbulence Ping rate 16 Hz Angle of beams 25° Maximum profiling range (broadband) 25 m Max number of bins 256 Memory capacity Up to 128GB (able to upgrade as needed) Firmware upgrades Wave data and fine-scale turbulence data upgrades available Minimum blanking distance 10 cm (broadband and HR mode) Minimum bin size 20 cm in broadband; 0.2 cm in HR mode Firmware upgrades as needed Wave measurements, HR using 5th beam
