Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

Creator:

Pierce, Stephen D.

Abstract:

We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

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...

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...
