Summary

Description

Shipboard acoustic Doppler current profiler data collected during the Integrated Acoustic and Trawl Surveys of Pacific Hake. Processing by: Stephen Pierce, Oregon State University (P. M. Kosro also performed some processing steps in the 1998 case) Date: 16 August 2006 Data quality: Good in general Missing or poor-quality data have been omitted. This dataset has a simple simple version of observed velocities, useful for most purposes. The complete data sets with all configuration and processing details and diagnostic data (e.g. error velocity, AGC, spectral width) are available from the NODC Joint Archive for Shipboard ADCP, or by request from S. Pierce. Processing steps included: editing of the data using various diagnostics, calibration of the phase and amplitude errors of the ADCP/navigation/gyrocompass system by covariability analysis between currents and ship velocity, reference layer velocity smoothing, and final production of earth-referenced velocities.
