Collection and Processing of Shipboard ADCP Velocities from the Barents Sea PolarFront Experiment

摘要

The Barents Sea Polar Front Experiment was a combined physical oceanography andacoustic tomography field study which took place from 6-26 August 1992. Both shipboard and moored data were collected in a 80 x 70 km experimental region on the south flank of Spitsbergen Bank about 60 km east of Bear Island. Of principal interest in this report are the data from an Acoustic Doppler Current Profiler (ADCP) which was operated continuously during the experimental period as a part of the shipboard instrumentation aboard the USNS BARTLETT. This report describes the configuration and operation of the ADCP, the space-time sampling grid on which the data were collected, the determination of absolute velocity from the ADCP measurements, and the application and results of a tide removal technique which allowed estimation of the sub-tidal flow.
