Tidal And Subtidal Lateral Structures Of Density And Velocity In The Chesapeake Bay Entrance, Austreberto Cristobal Reyes-Hernandez

OES Theses and Dissertations

Hydrographic and velocity data collected along the Chesapeake Bay Entrance during seven 25-hours cruises centered around neap or spring tides, were used to assess the fortnightly variability in the transverse structure of the tidal and subtidal density and velocity fields. Amplitude and phase of the semidiurnal and diurnal harmonics reflected the influence of bathymetry, buoyancy conditions and fortnightly variability. Tidal amplitudes were almost twice as large in springs than in neaps. Both Chesapeake and North Channels had similar along-channel amplitudes, which suggested a higher vertically integrated mixing energy in North Channel. Tidal velocity convergences were more intense for springs than …
