Principles of operation
- Which assumptions are made during measurements with ADCP instruments?
- What are the different coordinate systems and how are they defined?
- Where can I find instrument software and firmware?
- Do you have any information about the Signature AHRS?
- How does the AquaPro HR measure currents?
- Can you use the AquaPro HR Amplitude to estimate Suspended Sediment Concentration? What about bottom distance check?
- What is the HR mode on the Aquadopp Profiler? What should I use the Aquadopp Profiler HR for?
- What is a pre-Midlife/Midlife/AD2CP instrument?
- Will my ADCP negatively affect marine animals?
- How do I find the equivalent two-way beam angle Ψ for my echo sounder?
- How do I calculate current speed and direction from three beam ADCP velocity components?
- What is the wave velocity cell and how is it used?
- What is the effect of temperature gradients when estimating the surface level?
- Can you get velocity measurements from the fourth beam on the AWAC?
- What is the difference between Z and Up?
- What is sidelobe interference? Why does it occur?
- How is wave direction defined?
- What factors affect maximum profiling range?
- Does the Signature series have full 3D compass and tilt readings?
- What is the minimum velocity an ADCP can measure?
- What are the different Doppler measurement techniques? How do they compare?
