Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

Creator:: Osborne, John J.
Abstract:: Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

Spatial and Temporal Variability of the M2 Internal Tide Generation and Propagation on the Oregon Shelf

Creator:: Osborne, J. J., Kurapov, A. L., Egbert, G. D., and Kosro, P. M.
Abstract:: A 1-km-horizontal-resolution model based on the Regional Ocean Modeling System is implemented along the Oregon coast to study average characteristics and intermittency of the M₂ internal tide during summer upwelling. Wind-driven and tidally driven flows are simulated in combination, using realistic bathymetry, atmospheric forcing, and boundary conditions. The study period...

Combined Effects of Wind-Driven Upwelling and Internal Tide on the Continental Shelf

Creator:: Kurapov, A. L., Allen, J. S., and Egbert, G. D.
Abstract:: Internal tides on the continental shelf can be intermittent as a result of changing hydrographic conditions associated with wind-driven upwelling. In turn, the internal tide can affect transports associated with upwelling. To study these processes, simulations in an idealized, alongshore uniform setup are performed utilizing the hydrostatic Regional Ocean Modeling...

Seasonal Cross-Shelf Flow Structure, Upwelling Relaxation, and the Alongshelf Pressure Gradient in the Northern California Current System

Creator:: McCabe, Ryan M., Hickey, Barbara M., Dever, Edward P., and MacCready, Parker
Abstract:: Moored 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 is employed to eliminate meander- and eddy-induced biases in the cross-shelf flow that are unaccounted for with an alternative, commonly...

Optics, structure and variability of the offshore Columbia River plume

Creator:: Saldías, Gonzalo
Abstract:: The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...

Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

Creator:: Pasmans, Ivo
Abstract:: Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...
