In contrast, sounds had no effect when participants searched for names rather than pictures of objects. For example, finding a cat was faster when participants heard a meow sound. Using a visual search paradigm, we demonstrated that characteristic sounds facilitated visual localization of objects, even when the sounds carried no location information. A hiding cat may meow, or the keys in the cluttered drawer may jingle when moved. In a natural environment, objects that we look for often make characteristic sounds. Iordanescu, Lucica Guzman-Martinez, Emmanuel Grabowecky, Marcia Suzuki, Satoru Visually the waves appear in fair weather as a strong foam front, which is less visible the farther they propagate.Ĭharacteristic sounds facilitate visual search. Their eventual dissipation may contribute significantly to surface mixing locally, particularly in comparison with the local dissipation due to the tides. The waves appear to be generated with the ebb flow along the tidal flats of the Stillaguamish River, and the speed and width of the resulting waves can be predicted from second-order KdV theory. Acoustic Doppler current profiler (ADCP) measurements were attempted, but unsuccessful. Intermittent large amplitude internal waves observed in Port Susan, Puget SoundĪ previously unreported internal tidal bore, which evolves into solitary internal wave packets, was observed in Port Susan, Puget Sound, and the timing, speed, and amplitude of the waves were measured by CTD and visual observation. The user interface was based on the IDL widget concept. The data set was visualized using IDL image tools overlayed with contour routines. A graphical user interface, WASAT ( WAve Spectrogram Analysis Tool), using the Interactive Data Language was created. The data set was decoded from its original data format which was the NASA DITES I/II format. A specific application for the visualization of three dimensional wave HF FFT spectra obtained from the SCIFER sounding rocket launched January 25, 1995, is made. The report describes a technique for the decoding and visualization of sounding rocket data sets.
