Field Calibration of Mixed-Layer Drifters
Publisher: American Meteorological Society
Abstract: A set of field experiments was conducted to determine the water-following characteristics of mixed-layer drifters with ?holey-sock? drogues. Through the use of a drifting current meter array, direct estimates of slip ...
The Role of Advection, Straining, and Mixing on the Tidal Variability of Estuarine Stratification
Publisher: American Meteorological Society
Abstract: ata from the Hudson River estuary demonstrate that the tidal variations in vertical salinity stratification are not consistent with the patterns associated with along-channel tidal straining. These observations result from ...
Shear Instability in a Highly Stratified Estuary
Publisher: American Meteorological Society
Abstract: Shear instability is found to be the principal mechanism of vertical exchange within the pycnocline of a salt wedge estuary. A field program involving high-resolution velocity and density measurements, as well as high-frequency ...
The Alongshore Transport of Freshwater in a Surface-Trapped River Plume
Publisher: American Meteorological Society
Abstract: The alongshore transport of a surface-trapped river plume is studied using a three-dimensional model. Model simulations exhibit the previously observed rightward veering (in the Northern Hemisphere) of the freshwater and ...
An Idealized Study of the Structure of Long, Partially Mixed Estuaries
Publisher: American Meteorological Society
Abstract: Classic models of estuarine circulation are reexamined using a three-dimensional, primitive equation numerical ocean model. The model is configured using an idealized estuary/shelf domain with rectangular cross section, ...
Tide-Induced Variation of the Dynamics of a Salt Wedge Estuary
Publisher: American Meteorological Society
Abstract: The time variations of the salt wedge intrusion in the Fraser estuary, British Columbia, were monitored during a variety of tidal and run-off conditions using instruments and sampling methods that provided high resolution ...
Hydraulic Control of a Highly Stratified Estuarine Front
Publisher: American Meteorological Society
Abstract: Observations at the mouth of the Fraser River (British Columbia, Canada) indicate an abrupt frontal transition between unstratified river outflow and a highly stratified river plume with differences in salinity greater ...
Sources of Drag in Estuarine Meanders: Momentum Redistribution, Bottom Stress Enhancement, and Bend-Scale Form Drag
Publisher: American Meteorological Society
Subtidal Salinity and Velocity in the Hudson River Estuary: Observations and Modeling
Publisher: American Meteorological Society
Abstract: A tidally and cross-sectionally averaged model based on the temporal evolution of the quasi-steady Hansen and Rattray equations is applied to simulate the salinity distribution and vertical exchange flow along the Hudson ...
The Temporal Response of the Length of a Partially Stratified Estuary to Changes in River Flow and Tidal Amplitude
Publisher: American Meteorological Society
Abstract: The temporal response of the length of a partially mixed estuary to changes in freshwater discharge Qf and tidal amplitude UT is studied using a 108-day time series collected along the length of the Hudson River estuary ...
