RISThe Response of a Steep-Sided, Narrow Canyon to Time-Variable Wind Forcing
Publisher: American Meteorological Society
Abstract: The response of a relatively narrow (?7 km wide) and deep (?450 m deep) steep-sided (up to 45° bottom slope) submarine canyon to strong wind forcing is explored using data from an 18-element moored array as well as CTD ...
Alongshore Coherence on the Pacific Northwest Continental Shelf (January–April, 1975)
Publisher: American Meteorological Society
Abstract: During the winter and spring of 1975, current observations were made simultaneously at five locations between Tofino, British Columbia, and Newport, Oregon, a distance of 480 km. Sea level and atmospheric pressure observations ...
The Fluctuating Longshore Pressure Gradient on the Pacific Northwest Shelf: A Dynamical Analysis
Publisher: American Meteorological Society
Abstract: The majority of papers on Pacific Northwest shelf dynamics have emphasized the relationship between longshore wind stress τ3, and longshore velocity v. However, attempts to illustrate a balance of momentum in the longshore ...
A Spin-Up Model as a Diagnostic Tool for Interpretation of Current and Density Measurements on the Continental Shelf of the Pacific Northwest
Publisher: American Meteorological Society
Abstract: The primary goal of this paper is to prescribe the practical limitations of the two-dimensional, baroclinic, time-dependent model of Hamilton and Rattray (1978) for the Oregon-Washington continental shelf. A unique time ...
Barotropic and Baroclinic Tides over the Continental Slope and Shelf off Oregon
Publisher: American Meteorological Society
Abstract: During the Coastal Upwelling Experiment of 1973, several current meter moorings were deployed on the Oregon continental shelf and slope. Data from 16 current meters and temperature sensors which were deployed along a line ...
Application of Remote Wind-Forced Coastal Trapped Wave Theory to the Oregon and Washington Coasts
Publisher: American Meteorological Society
Abstract: The theory of coastal trapped waves generated by remote wind forcing (Clarke) is used to calculate coastal subsurface pressure (SSP) and longshore velocity along the Oregon and Washington coasts for three two-month periods: ...
The Role of a Longshore Pressure Gradient in Pacific Northwest Coastal Dynamics
Publisher: American Meteorological Society
Abstract: In this paper we demonstrate the importance of the seasonal barotropic longshore pressure gradient force to Pacific Northwest coastal dynamics. Values of the seasonal longshore pressure gradient corrected for gauge height ...
Ebb-Tide Dynamics and Spreading of a Large River Plume
Publisher: American Meteorological Society
Abstract: Momentum balances in the near-field region of a large, tidally pulsed river plume are examined. The authors concentrate on a single ebb tide of the Columbia River plume, using the Regional Ocean Modeling System (ROMS) ...
Seasonal Cross-Shelf Flow Structure, Upwelling Relaxation, and the Alongshelf Pressure Gradient in the Northern California Current System
Publisher: American Meteorological Society
Abstract: oored observations are used to investigate the seasonal change in vertical structure of the cross-shelf circulation at a midshelf location in the northern California Current System. A streamwise?normal coordinate system ...
Coastal Trapped Waves, Alongshore Pressure Gradients, and the California Undercurrent*
Publisher: American Meteorological Society
Abstract: he California Undercurrent (CUC), a poleward-flowing feature over the continental slope, is a key transport pathway along the west coast of North America and an important component of regional upwelling dynamics. This study ...
