An Adaptive Approach to Derive Sea Ice Draft from Upward-Looking Acoustic Doppler Current Profilers (ADCPs), Validated by Upward-Looking Sonar (ULS) Data

Estimation of Surface Winds From Upward Looking Acoustic Doppler Current Profilers

Three upward looking acoustic Doppler current profilers (ADCP) were deployed beneath meteorological buoys in the Gulf of Tehuantepec, Mexico, during winter 1988-1989. Hourly averaged wind speed data from the buoys and from ship when in the vicinity were compared with surface acoustic backscatter intensity recorded at the ADCPs. The backscatter was found to be a significant predictor of wind spe...

Wave Measurements Using Upward Looking Sonars in Marginal and Polar Sea Ice Regimes

“wavesonar” - an Upward-looking Sonar for Wave Measurements on the Continental Shelf

An upward-looking sonar instrument, the Ice Profiling Sonar (IPS), has been developed, and successfully used for obtaining time series measurements of ice keel depths over the continental shelves of the Arctic in support of scientific research. The IPS instrument capabilities have since been expanded to provide accurate measurement of ocean waves. This new instrument, the WaveSonar, uses a high...
