b'HEADLINETECHNICAL TIPSAccurate Wave MeasurementHow to select the best method for measuring ocean & coastal waves.INGER GRAVES,Ocean & Coastal Product Management Leader Aanderaa, a Xylem brandAccurate Wave measurements are critical in applications such as offshore wind farm development,Three Wave Measurement Methodsnavigation, cable laying, breakwater building, and bridge construction. Waves also result in continuous loads on marine structures, including docks, moorings, and offshore platforms. 1 Accelerometer on a buoy at the surface to Waves are challenging to measure. Variables to considercalculate wave height.when collecting wave data include the depth of the measuring device, proximity to shore, wave types, and available infrastructure from which to measure. Several methods for measuring waves are available, andMeasuring careful selection of the best approach is needed to getorbital the optimal result.movement at a given depth to calculate Measurement MethoDswave height.There are three different methods available tomeasure wave characteristics:1.) Surface buoys can be equipped with sensorsthat measure the buoys movement.2.) Acoustic profilers can measure orbitalcurrents in the water column.Pressure SensorMeasuringpressure 3.) Pressure sensors can be placed in uctuation at a given depth to the water column.calculate wave height.
