Near-Surface Dynamics of a Separated Jet in the Coastal Transition Zone off Oregon

Abstract

Three-dimensional circulation in the coastal transition zone (CTZ) off Oregon is studied using a 3-km resolution model based on the Regional Ocean Modeling System (ROMS). The study period is spring-summer 2002, when extensive observations are available from the North Eastern Pacific Component of the Global Ocean Ecosystems Dynamics (GLOBEC-NEP) project. Our main focus is on near-surface transports, particularly in an area off Cape Blanco where an energetic coastal current is separated in the CTZ. Comparisons with available observations (velocities from mid-shelf moorings, surface velocities from high-frequency radars, satellite SST maps, along-track SSH altimetry, and SeaSoar hydrography) show that the model reproduces qualitatively correctly the flow structure and variability in the study area.
