Inertial Current in Lake Ontario, Winter 1972–73 (IFYGL)
Publisher: American Meteorological Society
Abstract: Nearly four months of continuous current and temperature data, taking during the 1972?73 winter depths of about 15 and 75 m in Lake Ontario, have been analyzed for evidence of inertial oscillations. The data, collected as ...
On Estimating Wind Velocity Using an Upward-Looking ADCP
Publisher: American Meteorological Society
Abstract: A new set of measurements made using an upward-looking broadband acoustic Doppler current profiler (ADCP) is analyzed for ?surface velocity,? which previous investigations suggest is related to wind velocity. In the present ...
Spatial Processing of Range-Bin ADCP Data to Resolve Small-Scale Frontal Features
Publisher: American Meteorological Society
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 ...
Use of Single-Ping Bottom-Track ADCP Data to Characterize Small-Scale Bathymetry
Publisher: American Meteorological Society
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. ...
Calibrating a Gyrocompass Using ADCP and DGPS Data
Publisher: American Meteorological Society
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 ...
Near-Surface Current Measurements Using a Ship-Deployed “Horizontal” ADCP
Publisher: American Meteorological Society
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 ...
Convergence and Downwelling at a River Plume Front
Publisher: American Meteorological Society
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 ...
Empirical Orthogonal Function Analysis of Ocean Surface Currents Using Complex and Real-Vector Methods
Publisher: American Meteorological Society
Abstract: Empirical orthogonal function (EOF) analysis has been widely used in meteorology and oceanography to extract dominant modes of behavior in scalar and vector datasets. For analysis of two-dimensional vector fields, such as ...
