Electromagnetic current meter. Figure 3-6 shows the spectrum for the 

 raw signal and the raw and low-pass time series for Channel 36 (CM5, cross- 

 shore component, located approximately 1.7 ft below the mean water eleva- 

 tion) for Run A301 1A. Note that the general appearance of the raw time 

 series is inverted from the wave time series in Figure 3-3. Because the 

 SUPERTANK coordinate system defines the cross-shore coordinate as positive
