Find answers to your questions about waves and wave measurement.

• My instrument is set up to measure in XYZ, but the waves are presented in ENU?
• What is the Wave Velocity Cell and how is it used?
• What is the effect of temperature gradients when estimating the surface level?
• What effect does the "mounting height" selection have in the deployment planning?
• Does White capping cause problems for the AST beam?
• What should I put in the "Waves - static mode" edit boxes (AWAC deployment planning panel)
• Is there a lag between the sampling time of pressure and velocity measurements in the Aquadopp/AquaPro when used in wave mode?
• What is the longest average interval possible on AWAC without skipping a measurement?
• Why does my AWAC AST appear to miss the surface and have bad/missing detects?
• What do the AWAC Error Codes mean?
• Why is there a minimum average interval on AWAC?
• How long can we measure waves?
• How is wave direction defined?
• The velocity for each beam is given in m/s, but what is the direction?
• What is the difference between Hm0 and Hs?
• Timing of wave burst – Conflict or not between waves and currents?
• What types of quality criteria are made when checking the AST data?
• How can I identify reflected waves in my processed data?
• What is the difference between AST Distance 1 and AST Distance 2 (.WAD)?
• Why is there a difference between mean pressure and the mean AST?
• Does the AST measure distance from effectively the same point on the instrument as the pressure sensor?
• Should we use 1024 or 1200 number of wave samples?
• What is the minimum deployment depth for an AWAC?
