HLY-04-04 ADCP Data (5-min Averages) [Muenchow, A.]



The United States Coast Guard Cutter (USCGC) Healy contains a 75-kHz phased-array Acoustic Doppler Current Profiler (ADCP) (Ocean Surveyor) mounted under the hull to transmit and receive echos of acoustic pulses from which to estimate vertical profiles of horizontal currents. Attitude information such as heading, pitch, and roll is provided by an Ashtech ADU2-3DGPS receiver while position data are provided by a Trimble Centurion p-code DGPS system. These data streams provide earth-referenced absolute horizontal currents and their vertical variations from about 20-m below the surface to the bottom or about 400-m depth.
