Long-Term Observations of Turbulent Reynolds Stresses over the Inner Continental Shelf
Publisher: American Meteorological Society
Abstract: n situ observations of turbulent momentum flux, or Reynolds stresses, were estimated from a 10-yr acoustic Doppler current profiler (ADCP) record of inner-shelf velocities at the Martha?s Vineyard Coastal Observatory (MVCO) ...
Alongshelf Variability of Inner-Shelf Circulation along the Central Oregon Coast during Summer
Publisher: American Meteorological Society
Abstract: The spatial and temporal variability of inner-shelf circulation along the central Oregon coast during the 2004 upwelling season is described using a 70-km-long array of moorings along the 15-m isobath. Circulation at three ...
Time-Varying Across-Shelf Ekman Transport and Vertical Eddy Viscosity on the Inner Shelf
Publisher: American Meteorological Society
Abstract: The event-scale variability of across-shelf transport was investigated using observations made in 15 m of water on the central Oregon inner shelf. In a study area with intermittently upwelling-favorable winds and significant ...
A Comparison of Methods for Estimating Reynolds Stress from ADCP Measurements in Wavy Environments
Publisher: American Meteorological Society
Abstract: urbulent Reynolds stresses are now routinely estimated from acoustic Doppler current profiler (ADCP) measurements in estuaries and tidal channels using the variance method, yet biases due to surface gravity waves limit its ...
Wave-Driven Inner-Shelf Motions on the Oregon Coast
Publisher: American Meteorological Society
Abstract: Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes?Coriolis force). This analysis is extended using ...
Calculating Reynolds Stresses from ADCP Measurements in the Presence of Surface Gravity Waves Using the Cospectra-Fit Method
Publisher: American Meteorological Society
Abstract: Recently, the velocity observations of acoustic Doppler current profilers (ADCPs) have been successfully used to estimate turbulent Reynolds stresses in estuaries and tidal channels. However, the presence of surface gravity ...
Improving HF Radar Estimates of Surface Currents Using Signal Quality Metrics, with Application to the MVCO High-Resolution Radar System
Publisher: American Meteorological Society
Abstract: stimates of surface currents over the continental shelf are now regularly made using high-frequency radar (HFR) systems along much of the U.S. coastline. The recently deployed HFR system at the Martha?s Vineyard Coastal ...
The Spatial Structure of Tidal and Mean Circulation over the Inner Shelf South of Martha's Vineyard, Massachusetts
Publisher: American Meteorological Society
Abstract: he spatial structure of the tidal and background circulation over the inner shelf south of Martha's Vineyard, Massachusetts, was investigated using observations from a high-resolution, high-frequency coastal radar system, ...
