Wave height spectra are measured by a bottom-mounted, upward looking Acoustic Doppler Current Profiler (ADCP) using three independent methods: (1) Surface tracking (SSpec), (2) Pressure gage (PSpec), and (3) Wave orbital velocities (VSpec). The surface track-derived spectrum can become unreliable under smooth, glassy surface conditions. This typically corresponds to times when the wave height reported by the velocity-based spectrum is less than 10cm. The ADCP is located several hundred yards off the Gloucester Point fishing pier in about 10-11m water depth. It should be noted that wave parameters derived from the pressure sensor have little meaning given the significant depth-attenuation of the pressure signal for short-period waves.
