Abstract: To extract the maximum quality results from shipborne acoustic Doppler current profiler data, it is necessary to know how the beams are aligned with respect to the earth. Individual beam velocities, relative to the water ...

Abstract: Current-meter measurements indicate the presence of a mean Ekman spiral imposed upon the dominant tidal oscillation of the St. Lawrence estuary. Estimates of vertical eddy coefficients are consistent with previous estimates. ...

Abstract: An array of three current meters were anchored on the continental shelf of the East China Sea during the last half of February 1975 as part of the Japanese Air Mass Transformation Experiment, AMTEX-75. The results indicate ...

Abstract: A new approach is proposed for the processing of acoustic Doppler current profiler (ADCP) data that has the potential to better resolve the structure of small-scale dynamical features such as strongly convergent current ...

Abstract: A shipboard acoustic Doppler current profiler, in its bottom-track mode, estimates the radial velocity of the transducer relative to the bottom and the range from the transducer to the bottom for each beam of each ping. ...

Abstract: Accurate values of ship?s heading, usually obtained from a gyrocompass, are vital in calculating absolute currents from ship-mounted acoustic Doppler current profilers (ADCPs). This note presents a straightforward method ...

Abstract: It is demonstrated that a data set collected by the combined use of a Doppler shear profiler and a towed thermistor chain can provide a detailed description of a midocean near-surface front. The front described was encountered ...

Abstract: An experiment was performed to measure the near-surface current by aiming horizontally two of the beams from an acoustic Doppler current profiler (ADCP) deployed at 0.6-m depth from an anchored (but rolling) ship. The ...

Abstract: The small-scale structure of the circulation and hydrography at the frontal boundary of the Connecticut River plume in Long Island Sound has been resolved using a novel combination of instruments: a towed acoustic Doppler ...

Abstract: This work examines the presence of internal-inertial waves in a front in the North Atlantic subtropical convergence zone. Results of Doppler shear profiler and towed thermistor chain surveys are displayed to document the ...
