Seasonal Variations in the Circulation over the Middle Atlantic Bight Continental Shelf
Publisher: American Meteorological Society
Abstract: Fits of an annual harmonic to depth-average along-shelf current time series longer than 200 days from 27 sites over the Middle Atlantic Bight (MAB) continental shelf have amplitudes of a few centimeters per second. These ...
Current Dynamics over the Northern California Inner Shelf
Publisher: American Meteorological Society
Abstract: Subtidal current dynamics at a northern California inner-shelf site are analysed using moored current observations in 30 m of water, in conjunction with wind and bottom pressure measurements acquired during the summer of ...
The Mean Along-Isobath Heat and Salt Balances over the Middle Atlantic Bight Continental Shelf
Publisher: American Meteorological Society
Abstract: The mean heat and salt balances over the Middle Atlantic Bight continental shelf are investigated by testing the hypothesis that surface fluxes of heat or freshwater are balanced by along-isobath fluxes resulting from the ...
The Accuracy of Tide-Gauge Measurements at Subtidal Frequencies
Publisher: American Meteorological Society
Abstract: The accuracy of subinertial sea level, as measured by tide gauges in the Southern California Bight, is investigated. Sea level differences formed from tide gauges separated by less than 50 km are examined. The observed ...
Sensitivity of the Inner-Shelf Circulation to the Form of the Eddy Viscosity Profile
Publisher: American Meteorological Society
Abstract: The sensitivity of the inner-shelf circulation to the form of the vertical mixing is examined using a steady, linear, two-dimensional, eddy viscosity model. For both alongshelf wind stress and pressure gradient forcing, ...
Observations and a Model of the Mean Circulation over the Middle Atlantic Bight Continental Shelf
Publisher: American Meteorological Society
Abstract: Analyses of current time series longer than 200 days from 33 sites over the Middle Atlantic Bight continental shelf reveal a consistent mean circulation pattern. The mean depth-averaged flow is equatorward, alongshelf, and ...
The Influence of Stratification on the Wind-Driven Cross-Shelf Circulation over the North Carolina Shelf
Publisher: American Meteorological Society
Abstract: Wind-driven, cross-shelf circulation is studied using current observations spanning the 90 km wide North Carolina shelf. Most of the shelf is less than 40 m deep. Current measurements were made at five sites within 16 km ...
The Surface Boundary Layer in Coastal Upwelling Regions
Publisher: American Meteorological Society
Abstract: Observations from the Oregon, northwest Africa, Peru, and northern California shelves are used to examine the characteristics of the surface boundary layer in coastal regions during the upwelling season. The observations ...
Inner-Shelf Response to Cross-Shelf Wind Stress: The Importance of the Cross-Shelf Density Gradient in an Idealized Numerical Model and Field Observations
Publisher: American Meteorological Society
Abstract: his study investigates the effects of horizontal and vertical density gradients on the inner-shelf response to cross-shelf wind stress by using an idealized numerical model and observations from a moored array deployed ...
The Influence of Wind Forcing on the Chesapeake Bay Buoyant Coastal Current
Publisher: American Meteorological Society
Abstract: Observations of the buoyant coastal current that flows southward from Chesapeake Bay are used to describe how the thickness, width, and propagation speed vary in response to changes in the along-shelf wind stress. Three ...
