23. Mooring Line “Strum” and Vortex Shedding

24. Quality Evaluation Data –Measure a profile and see SHEAR to identify if mooring line eddies, buoys or floats are causing errors in bins near transducer. –Error Velocity –Correlation

25. What is novel about the TRDI solution? Four beam (Janus) configuration –Velocity QA - error velocity to indicate flow inhomogeneity (e.g. mooring line interference) –Redundancy – reliability; allows three beam solution when one beam is blocked (e.g. by bio-growth or fish) –Fish rejection QA – iterative algorithm preventing biased velocity data by rejecting beam measurements biased by fish and strong scattering layers Relative backscatter – echo intensity to indicate signal levels

26. What is novel about the TRDI solution? Data Quality Assurance - Signal Processing –Correlation values – velocity data confidence –BroadBand Signal processing for high precision outlier rejection –HPR Sensor variability parameters – data confidence Power Savings –50-100 velocity measurements per sample to allow mm/s precision in one second –power saving
