Comparison of PEGASUS and Combined CTD/ADCP (Acoustic Doppler Current Profiler) Current Profiles off the California Coast.

摘要

Vertical profiles of alongshore and cross-shore velocities obtained by PEGASUS, free-falling, acoustically tracked current profiler, and an Acoustic Doppler Current Profiler (ADCP) are compared. Data was collected during November, 1988 near Point Sur, California. Processing of data for both instruments is discussed in some detail. Velocity profiles and contours show good correlation in feature location but often differed significantly in intensity. ALongshore velocity components from the two instruments were more highly correlated than were cross-shore components. Alongshore velocities also agreed well with both geostrophy and historical data.
