Description
Summary: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 frequency acoustic transducer (420 kHz), with a very narrow conical beam (2 width at-3 dB) to minimize the spatial smoothing of
